D-Backs Notes: Del Castillo, Thomas, Rotation
The Diamondbacks are expected to begin the year without catcher/first baseman Adrian Del Castillo. Manager Torey Lovullo said Monday that the 26-year-old is dealing with a left calf injury that’ll keep him out of game action for the bulk of Spring Training (link via Alex Weiner of Arizona Sports). He’ll be reassessed closer to Opening Day but it seems unlikely he’ll get enough exhibition reps to avoid a season-opening injured list stay.
Del Castillo is third on the catching depth chart after Gabriel Moreno and James McCann. He nevertheless had a strong chance to win a bench job if healthy. Tyler Locklear will begin the season on the IL as he rehabs elbow and shoulder surgeries. The lefty-hitting Del Castillo has a fair bit of first base and designated hitter experience. Arizona doesn’t have a ton of position player depth on the 40-man roster, leaving a couple bench jobs up for grabs.
After an encouraging 25-game debut two years ago, Del Castillo struggled last season. He struck out 47 times in 131 plate appearances (a near-36% rate) while hitting .242/.290/.392 over 44 games. The Miami product has posted strong numbers throughout his minor league career, but they’ve always come with a concerning level of swing-and-miss. He’s a below-average defensive catcher, putting more pressure on the bat if most of his work comes in the first base/DH mix.
Pavin Smith and Carlos Santana are projected for a first base platoon. They’ll also get a decent number of DH reps, while Lovullo said Ketel Marte will log some time there in addition to his primary second base work. The D-Backs are reportedly poking around the trade market for a utility piece after they dealt Blaze Alexander to Baltimore for reliever Kade Strowd and a pair of minor leaguers. They’ll ideally find someone with more offensive punch than Tim Tawa and non-roster invitees Ildemaro Vargas and Jacob Amaya to play that role.
The bottom half of the lineup would be an even bigger concern if Corbin Carroll opens the season on the IL. Arizona’s star right fielder will miss most of Spring Training following last week’s hamate surgery. The hope is for Carroll to make it back by the beginning of the regular season. Fellow outfielder Alek Thomas tells Nick Piecoro of The Arizona Republic that he’s working mostly between left and center field with the expectation that Carroll will be in his typical position on Opening Day.
Thomas has played all three outfield positions in the minor leagues. He has played exclusively center field as a big leaguer, logging more than 3000 innings up the middle. Thomas is a quality defender who shouldn’t have any issue adjusting to a corner if the D-Backs need him to move around. Arizona is trying to get Jordan Lawlar acclimated to playing center field.
Lawlar has a higher offensive ceiling than Thomas has shown over 420 MLB contests, so the latter would be best suited for a fourth outfield role if everyone’s healthy. They’ll probably need both players in the starting lineup to begin the season, as Lourdes Gurriel Jr. will also open the year on the injured list after last summer’s ACL injury. Thomas could be a stopgap left fielder until Gurriel returns and/or prospect Ryan Waldschmidt plays his way to the big leagues.
There’s a fair bit of opportunity in one of the more top-heavy lineups in MLB. Carroll, Marte, Moreno and Geraldo Perdomo make for an excellent top half of a batting order. Nolan Arenado is on the downside of his career but should still be a solid everyday third baseman. The bottom third of the lineup and most of the bench is a lot less established.
It’s not quite as extreme on the pitching side, but there are some parallels. Free agent returnees Merrill Kelly and Zac Gallen are locked into the rotation; Lovullo has already named Kelly his Opening Day starter. Ryne Nelson figures to have a mid-rotation spot secure, but the Diamondbacks aren’t making any firm commitments beyond that.
“I can’t even really make comments about any projections or what the starting rotation is going to look like,” Lovullo told reporters (including Steve Gilbert of MLB.com). Right now, it looks as if Eduardo Rodriguez, Brandon Pfaadt and Michael Soroka are battling for two spots. Rodriguez and Soroka will be on the MLB roster, but Pfaadt has a pair of minor league options and could open the season in Triple-A. Soroka has the most experience of that group in a swing role and would be the most familiar with pitching in long relief if the D-Backs want all six pitchers on the active roster with a five-man rotation. One injury might take the decision out of Lovullo’s hands, but it’s another camp battle that Arizona fans will want to follow during exhibition play.
D-backs Notes: Lawlar, Burnes, Bullpen, Santana
The Diamondbacks’ acquisition of future Hall of Famer Nolan Arenado (alongside their decision not to trade Ketel Marte) pushed longtime top prospect Jordan Lawlar out of the club’s infield mix, at least on paper. That’s led to some questions about his role moving forward, but manager Torey Lovullo revealed to reporters (including Alex Weiner of AZ Sports) yesterday where the team hopes to play Lawlar going forward: center field. That would displace incumbent center fielder Alek Thomas, who Lovullo suggested would move around the outfield amid injuries to Lourdes Gurriel Jr. and Corbin Carroll.
Of course, that plan to play Lawlar in center field is predicated on him proving himself capable of handling the position this spring. He played three games in center during the Dominican Winter League this offseason, but otherwise has spent his entire professional career on the dirt. His 98th percentile sprint speed in 2025 certainly suggests he has the wheels to handle the position, offering plenty of reason for optimism, but that lack of experience calls into question how effectively he’ll be able to pick up the position on the fly. It wouldn’t be the first time a team converted an infield prospect to center over the course of one Spring Training, as the division rival Padres managed to do just that with Jackson Merrill two years ago. Merrill turned in one of the best defensive seasons in the entire sport as a rookie, and should offer some optimism about Lawlar’s ability to follow suit.
Perhaps the biggest question for Lawlar isn’t whether he’s physically capable of handling center field, but whether he’s capable of staying on the field long enough to prove it. Between Triple-A and the majors, Lawlar has just 113 games played over the past two seasons due to a variety of injuries. Last season, he missed multiple months with a hamstring strain, while a thumb injury cost him most of 2024. In between those injuries, he’s struggled in brief cameos at the big league level but has managed to continue raking at Triple-A, offering some reason for optimism that he’ll figure things out offensively if given consistent playing time. He’ll now get that playing time at the expense of Thomas, who was once a former top propsect himself but has never quite managed to hit well in the majors with a career 74 wRC+ that peaked at 81 last season. Thomas figures to join Jorge Barrosa, Tim Tawa, and perhaps non-roster invitees like Ildemaro Vargas and Ryan Waldschmidt in mixing and matching in the corners while Carroll and Gurriel are out of commission.
Turning to the pitching staff, ace right-hander Corbin Burnes missed much of his first season in Arizona due to Tommy John surgery but figures to contribute after completing his rehab at some point this year. Burnes himself spoke to reporters (video link via MLB.com) about his timeline for return yesterday, and suggested that he’s expecting to return around the All-Star break. Burnes added that he plans to “try and make it [back] sooner,” though considering he went under the knife in June that could be a tall ask given the procedure’s typical recovery timeline. Adding Burnes back to the rotation would obviously be a massive boost. The former Cy Young award winner had a 2.66 ERA in 11 starts last year (albeit with less impressive peripherals) and placed in the top ten in Cy Young voting in each of the past five seasons prior to his injured 2025 campaign.
Burnes will be working towards a return alongside the team’s two highest leverage relievers, Justin Martinez and A.J. Puk. It appears his projected timeline falls in the middle of the two relief arms, as described by the players themselves in comments made to AZ Sports. Martinez suggested that he’s anticipating a return in August of this year, though he acknowledged it “could be earlier, could be later” depending on how things go from here. He underwent Tommy John surgery in June, like Burnes did. Puk also went under the knife in June, but he underwent a less-invasive internal brace procedure. The southpaw told reporters he hopes to be back by the end of May, but acknowledged that isn’t necessarily realistic. Still, he expressed confidence that he’ll be back on the mound before the second half, which indicates he could be looking at a return to action at some point in June.
Adding Puk and Martinez back to the relief staff could be majorly impactful for the Diamondbacks given their difficulties in finding high leverage relief help this year. The team figures to run back more or less the same group of relievers they finished last year with, as non-roster invitee Jonathan Loaisiga figures to be the most impactful reliever added to the roster during the offseason. Loaisiga has struggled to stay healthy over the years, and while he has a career 3.54 ERA at the big league level he struggled last year with middling results and worrisome peripherals (including a 5.83 FIP) in 30 appearances for the Yankees.
While Burnes, Puk, and Martinez all figure to spend Spring Training rehabbing their injured elbows, first baseman Carlos Santana figures to be preparing for the World Baseball Classic. Santana was one of many players who was unable to secure insurance to play in the World Baseball Classic, but Ken Rosenthal of The Athletic reports that the Diamondbacks decided to give Santana the green light to play in the tournament uninsured. He’ll represent the Dominican Republic alongside teammate Ketel Marte and Geraldo Perdomo, and Hazen indicated that giving Santana the opportunity to bond with his new teammates over the shared experience of representing their home country was a factor in the team’s decision to assume the financial risk of the soon to be 40-year-old veteran getting injured. Santana is slated to make $2MM this year on his one-year deal with Arizona, and Rosenthal notes that, according to club GM Mike Hazen, Santana’s ability to be a clubhouse leader and guide other players on the team was a big part of why he was signed.
Jordan Lawlar Taking Center Field Reps In Winter Ball
Diamondbacks rookie Jordan Lawlar is playing winter ball in the Dominican Republic this offseason. He made his first appearance with the Tigres del Licey at an unfamiliar position: center field. It’s the first professional outfield experience for Lawlar, whose minor league and MLB work has been divided between second, third and shortstop.
Steve Gilbert of MLB.com wrote earlier this month that the D-Backs wanted Lawlar to get center field work alongside his usual infield responsibilities. The Diamondbacks haven’t made any decisions about a position change, but it behooves them to get a look at him in the outfield for a few reasons.
Lawlar’s defense was a significant issue late this year. The Diamondbacks finally opened everyday playing time for him at third base with the Eugenio Suárez deadline deal. Lawlar was on the minor league injured list for a couple weeks but was recalled at the end of August. His third base audition didn’t last long. Lawlar committed four errors in 76 innings, two apiece on September 7 and 14. Three of those were of the throwing variety. One of Lawlar’s errant throws led to a collision at first base that injured Tyler Locklear, who required surgeries on both his shoulder and elbow.
Scouting reports on Lawlar have generally praised his defensive ability. He was drafted as a shortstop and only moved to third base in deference to Geraldo Perdomo. It’s possible this year’s issues were a blip that’ll be corrected with a mechanical tweak or simply an offseason mental reset. The D-Backs didn’t want him in the field while they were chasing down a Wild Card berth, though. Manager Torey Lovullo kept Lawlar at DH or as a pinch-hitter after his game on September 14. Blaze Alexander played third base until the last game of the season — once the Snakes had been eliminated from contention.
The third base job should be open going into 2026. Alexander is a steady defender but doesn’t have huge upside at the plate. He’s better suited for a utility role. Lawlar, a career .298/.395/.515 hitter in the minors, has a higher ceiling. That wouldn’t matter much if the Diamondbacks don’t trust him defensively. They’re not going to lock him into full-time DH work at 23, but they probably wouldn’t feel great about handing him the starting third base job out of camp. He does still have an option remaining, yet they’re not going to learn much by sending him back to Triple-A Reno and letting him feast on Pacific Coast League pitching for another season.
John Gambadoro of Arizona Sports 98.7 FM writes that the D-Backs aren’t inclined to play Lawlar at second base. Ketel Marte might benefit from a few more DH at-bats but remains the primary second baseman. The two outfield spots to the left of Corbin Carroll could be up for grabs.
Center fielder Alek Thomas is a .234/.277/.362 hitter in almost 1400 career plate appearances. The Diamondbacks will eventually need some kind of offense from that spot. Left field is in worse shape. Lourdes Gurriel Jr. tore his ACL in September. Jake McCarthy is coming off a .204/.247/.345 season. Prospect Ryan Waldschmidt may already be their best internal option, and he hasn’t played a game above Double-A.
McCarthy could be non-tendered, while Thomas is a potential change-of-scenery candidate. If Lawlar takes to center field in winter ball, that could allow the Diamondbacks to feel a little more comfortable entertaining Thomas trade talks. Lawlar himself could also be a trade chip, as he’d be their best bet at getting a controllable starting pitcher in return. The Diamondbacks are going to need at least one outfielder via free agency or trade either way, making this an interesting offseason storyline in the desert.
D-backs Have Listened To Offers On Outfield Depth
The Diamondbacks remain on the fringes of the NL postseason picture, sitting five and a half games out in the Wild Card chase. General manager Mike Hazen has said he hopes the team performs well enough to position itself as a late buyer, but the GM has also at least been listening to offers on some of his outfielders, Jon Heyman of the New York Post reports. That does not include star Corbin Carroll, unsurprisingly, but Heyman suggests names like Alek Thomas, Jake McCarthy, Lourdes Gurriel Jr. and Randal Grichuk have likely been discussed.
Of the four outfielders, Grichuk is the most obvious trade candidate. He’s playing the 2025 season on a one-year, $5MM contract. He’ll unlock a $250K bonus when he reaches his 200th plate appearance — he’s currently at 174 — and another $250K if he reaches 275 plate appearances.
Grichuk’s contract is structured such that Grichuk is owed a $2MM salary and a $3MM buyout on a $5MM mutual option for next year. That makes him a bit more expensive for the rest of the season than a standard one-year, $5MM contract would imply; he’d have about $634K in salary remaining at the time of the trade deadline but also that $3MM buyout and some potential incentive pay. Of course, the D-backs could make a trade more appealing by including cash to offset some of that backloaded 2025 salary.
The 2025 season hasn’t been Grichuk’s best, but he’s still hitting for power. The 33-year-old is batting .242/.282/.466 with seven homers, 13 doubles and a triple in his 174 trips to the plate. His 5.7% walk rate is right in line with his career mark. His 21.6% strikeout rate is down from his career level of about 25% but noticeably higher than the personal-best 16.5% clip he turned in last year in a more productive season with the Snakes.
Gurriel, 31, is a tougher sell from a trade standpoint. He’s being paid $14MM this season and is guaranteed $13MM in 2026 plus at least a $5MM buyout on a $14MM club option for the 2027 season. His .251/.299/.421 batting line (98 wRC+) already represents a down year, and any team to acquire him would know Gurriel will either opt into the remaining $18MM he’s guaranteed beyond the current season or go on a second-half tear and opt out. It’s not an appealing structure, and the Diamondbacks would probably need to eat a significant portion of the remaining money he’s owed to facilitate a trade.
Thomas and McCarthy are both controllable lefty-swinging outfielders, but neither is having a good season at the plate. Thomas, once touted as one of the top outfield prospects in baseball, has yet to hit in parts of four major league seasons. He’s an above-average runner and strong defensive center fielder, but this year’s .245/.295/.366 batting line (84 wRC+) is actually the best of the 25-year-old’s young career. He’s a lifetime .230/.276/.360 hitter in just under 1200 big league plate appearances.
McCarthy, on the other hand, has had plenty of big league success at the plate — just not in 2025. He hit .283/.342/.427 in 99 games back in 2022 (116 wRC+) and slashed .285/.349/.400 (110 wRC+) as recently as last season. He had a down year in 2023, however, and the 27-year-old has struggled to a career-worst .144/.228/.244 line (33 wRC+) in 102 trips to the plate this season.
That’s a relatively small sample, of course, and McCarthy has had some demonstrably poor luck. He’s hitting just .151 on balls in play — less than half the .328 career mark he carried into the season and some 130 points lower than the league average. McCarthy isn’t hitting the ball hard at all (83.9 mph average exit velocity, 23.7% hard-hit rate), but he also had poor batted-ball metrics even in his more productive 2022 and 2024 seasons. His 15.7% strikeout rate remains excellent, and McCarthy has walked at a solid 8.8% rate.
The D-backs optioned McCarthy to Triple-A after a rough three-week start and only recalled him back in late June. He batted .314/.401/.440 in 237 plate appearances with the Diamondbacks’ top affiliate in Reno and has put together an improved (albeit still diminished) .222/.300/.400 slash in his past 51 major league plate appearances.
Both Thomas and McCarthy are controllable for an additional three seasons. Both are eligible for arbitration for the first time this offseason. The Diamondbacks burned McCarthy’s final option year when they sent him down to Triple-A back in April. He’ll be out of minor league options next year. Thomas also entered 2025 with one option year remaining, but his is still intact, as he hasn’t been sent down at any point this season.
Diamondbacks’ Outfielders Drawing Trade Interest
The Diamondbacks are no stranger to dealing from their perennial outfield depth, and GM Mike Hazen tells Nick Piecoro of the Arizona Republic that his stock of center fielders is again drawing interest. Hazen wouldn’t rule out a trade eventually coming together. It doesn’t sound as though Arizona is actively shopping any of its outfield options but rather listening to fairly robust interest, given the lack of center field options in free agency and elsewhere on the trade market. Diamondbacks fans, in particular, will want to check out Piecoro’s piece for a full slate of quotes and insight from Hazen.
The Snakes have Corbin Carroll, Alek Thomas and Jake McCarthy lined up as their likely outfield heading into the 2025 season, with Lourdes Gurriel Jr. mixing into left field as well. There’ll likely be some rotation of that bunch through the outfield and DH spots throughout the season. (Gurriel, it should be noted, is not a center fielder and is not seemingly among the players most heavily inquired about at this time.)
Of the D-backs’ trio of center field-capable outfielders, only Thomas and McCarthy stand as feasible trade candidates. Carroll, the 2023 NL Rookie of the Year, had a slow start in 2024 but bounced back to form as the season went on, slashing .256/.348/.522 (136 wRC+) over his final 425 plate appearances. He signed an eight-year, $111MM extension after a brief but excellent 32-game cup of coffee late in the 2022 season. He’s a cornerstone player in Arizona. Other clubs have probably inquired all the same, but Carroll is staying put.
Thomas and McCarthy, however, are at least a bit more plausible as trade candidates. The former ranked as one of the game’s top prospects for years but has yet to solidify himself as a viable everyday player in the majors. He’s a plus defender and runner when healthy but has mustered only a .226/.271/.359 batting line in 916 trips to the plate in the majors.
Thomas, 24, doesn’t strike out at an alarming clip (19.3%) but also ranks third among 251 big league hitters (min. 900 plate appearances) with a 57.2% ground-ball rate dating back to 2022. That penchant for grounders has undercut what scouting reports tabbed as above-average raw power. Thomas did pop 18 homers between Double-A and Triple-A a couple seasons back, but he has only 20 homers in his 916 big league plate appearances. Without elevating the ball more regularly, he’s unlikely to hit for much power in the majors. That said, he did make plenty of hard contact this past season (91.6 mph average exit velocity, 48.6% hard-hit rate). Even if much of that happens on the ground, a player with Thomas’ speed should see a far better average on balls in play than both the .200 he posted in 2024 and the .260 he’s notched in his career. There’s plenty to like about Thomas, and there are surely teams in need of a center fielder who are hoping they can buy low.
McCarthy, 27, is another solid defender — perhaps not quite to the extent of a healthy Thomas — who turned in a sharp .285/.349/.400 batting line in 2024. He smacked eight homers, swiped 25 bags (in 31 tries) and showed very strong contact skills (15.8% strikeout rate). He doesn’t have much power but also doesn’t possess glaring platoon splits. McCarthy doesn’t walk as much as one would prefer from a prototypical leadoff hitter (6.3% in 2024, 7.1% career), but he makes enough contact and runs well enough to profile as a table-setter who can handle all three outfield spots.
Both Thomas and McCarthy have one minor league option remaining and are controllable for another four seasons, which only adds to their appeal for win-now and rebuilding clubs alike. The Royals, Phillies, Pirates, Reds, Mets and Yankees are just some of the teams that could be in the market for outfield help this winter (though some of those obviously depend on the outcome of more pressing free agent pursuits).
As notably, Hazen indicated that any trades from his big league roster would be made with an eye toward improving another area of the MLB squad. The D-backs could lose Christian Walker to free agency, for instance, leaving a potential void at first base. Hazen has already publicly indicated that he hopes to add another high-leverage reliever/closer, though Piecoro specifically calls out the fact that the D-backs aren’t likely to move multiple years of a controllable outfielder in a straight-up swap for a reliever.
Fans may speculate on the potential to effectively purchase someone like Thomas or McCarthy by taking on some or even all of the remaining $22.5MM on Jordan Montgomery‘s contract. That seems overwhelmingly unlikely. Four years of either Thomas or McCarthy would surely be valued at more than the remaining $22.5MM on that contract, and even Montgomery himself would probably still command several million dollars on a bounceback deal in free agency. Taking on his contract probably amounts to somewhere in the vicinity of $15MM in underwater money, and that sum isn’t nearly enough to persuade a team to part with a controllable big league outfielder.
Diamondbacks Activate Ryne Nelson, Recall Alek Thomas
The D-Backs made a handful of moves on tonight’s off day. Arizona activated Ryne Nelson from the 15-day injured list and recalled outfielder Alek Thomas from Triple-A Reno. The Snakes optioned Yilber Diaz and Blake Walston to open spots on the active roster.
Nelson’s return is the biggest development. The right-hander has had a strong second half, working to a 3.39 ERA while striking out more than 27% of opponents since the All-Star Break. Nelson outpitched Jordan Montgomery to solidify his rotation spot. He held that job until the middle of September, when a bout of shoulder inflammation sent him to the injured list.
That temporarily drew Montgomery back into the starting five. Arizona could use both Nelson and Montgomery out of the bullpen this weekend. The D-Backs will start Merrill Kelly tomorrow to kick off their weekend series with the Padres. They haven’t announced starters for their final two games. Eduardo Rodriguez and Brandon Pfaadt would be on schedule. They’re the third and fourth starters on paper, although Nelson had been handily outperforming both in the weeks leading to his IL placement. Zac Gallen tossed 97 pitches over six innings against the Giants yesterday. He’s potentially an option for Sunday on three days rest if the D-Backs are playing a must-win game.
Thomas returns to the outfield mix as a speed and defense option off the bench. The D-Backs optioned him to Triple-A in the middle of August. He suffered an injury within a week and was out of action until September 17. Thomas has only appeared in 37 MLB contests this year. He’s hitting .191/.248/.362 across 102 plate appearances. Jake McCarthy has surpassed him as the primary center fielder.
At 88-71, the Diamondbacks currently hold the final Wild Card spot. They’re percentage points behind the #5 seed Mets. Arizona is technically one game up on the 86-71 Braves, but the teams have an equal number of losses with Atlanta holding the tiebreaker. If the Braves were to win out, they’d leapfrog the D-Backs.
Atlanta’s final two games — scheduled for next Monday after this week’s hurricane-related postponements — are against the Mets. That means the Diamondbacks control their destiny. If Arizona wins out, they’d hang onto the sixth seed over the Mets even if the Braves passed them by also finishing 91-71.
There’s a lot at play. The Atlanta-New York postponement means there’s a good chance the D-Backs won’t know their fate until Monday, even though Arizona’s regular season ends on Sunday. The Mets are headed to Milwaukee this weekend, while the Braves host a Royals team that only needs one win (or a Twins loss) to punch its ticket to October.
Diamondbacks Notes: Moreno, Gurriel, Thomas, Lawlar
After a shocking run to the World Series last October, the Diamondbacks once again find themselves inching towards the playoffs with a 1.5-game lead over the Braves and Mets in the AL Wild Card race. Arizona is in the second of three spots, leaving Atlanta and New York in a tie for the third spot. While there’s still room for things to change, Fangraphs gives the Snakes a strong 86.4% chance of making the postseason for the second consecutive year when all is said and done. Even with those solid odds, the club will surely want all the help it can get to secure its positioning and head into the playoffs strong.
Fortunately, reinforcements are on the way as manager Torey Lovullo told reporters (including Alex Weiner of AZSports) that both catcher Gabriel Moreno and outfielder Lourdes Gurriel Jr. are “very close” to being activated from the injured list. The duo were scheduled to play in a game at the club’s Spring Training complex today where Moreno was set to both hit and catch while Gurriel would hit without playing the field. That leaves Moreno, who has been out for six weeks due to a groin strain, a bit closer to playing in the majors than Gurriel, who’s been out two weeks now with a strained calf.
Moreno, 24, is in his second season with the Diamondbacks after being acquired from the Blue Jays alongside Gurriel in the Daulton Varsho trade prior to the 2023 campaign. Moreno has established himself well as a solid two-way catcher and has posted a .262/.344/.385 slash line with a 105 wRC+ while playing excellent defense behind the plate. That two-way talent has left the Snakes missing Moreno dearly, as they’ve utilized a combination of the light-hitting but defensively gifted Jose Herrera alongside youngster Adrian Del Castillo, who sports a 138 wRC+ but questionable defense behind the plate.
As for Gurriel, the 30-year-old has hit .274/.316/.428 with a 105 wRC+ that’s identical to not only Moreno’s own figure from this year but also the production Gurriel posted in his first season with Arizona last year. Fortunately for Arizona, however, Gurriel’s absence hasn’t been felt as much as may have been initially expected due to an offensive explosion on the part of Pavin Smith, who has slashed an incredible .286/.385/.905 with four home runs in nine games since taking over for Gurriel in left field alongside Randal Grichuk. While Smith’s 72-homer pace is obviously not sustainable long-term, his hot streak has allowed the club to post MLB’s best offense by wRC+ (138) in September despite losing a key cog in their lineup for whom they didn’t have an obvious replacement at the ready.
Gurriel and Moreno aren’t the only two players who could be called upon to help the Diamondbacks headed into the postseason, however. According to a conversation between GM Mike Hazen and MLB.com’s Steve Gilbert, outfielder Alek Thomas and top infield prospect Jordan Lawlar are both regarded as “possible” contributors down the stretch and into the postseason. Thomas was optioned to the minors back in August and subsequently suffered an oblique strain at Triple-A but, per Gilbert, is nearly ready to return to action. Thomas has had another disappointing season offensively with a .191/.248/.362 slash line in 32 games at the big league level, but he offers excellent defense in all three outfield spots that could make him an asset in a bench role.
Lawlar, meanwhile, made it into just 13 games before the calendar flipped to September this year between thumb surgery and a hamstring strain but finally made it back into Triple-A earlier this week. Per Gilbert, Lawlar is expected to play winter ball this offseason to make up for the reps he lost to injury this year, but it’s not hard to imagine the club preferring the 22-year-old to their other bench infield options like Luis Guillorme and Kevin Newman headed into the postseason. Lawlar was similarly included on the club’s postseason roster last year, when he appeared in three games and went 0-for-1 with a walk and a run scored.
Diamondbacks Option Alek Thomas
The Diamondbacks have recalled infielder Blaze Alexander from Triple-A Reno. Going the other way in a corresponding move is outfielder Alek Thomas, who has been optioned to Reno. Prior to the official announcement, Nick Piecoro of the Arizona Republic was among those to relay on X that Alexander was in the clubhouse while Thomas’s locker was being cleared out.
Thomas, 24, gets sent to the minors for the first time in over a year, as he was last optioned in May of 2023. As of a few years ago, he was considered one of the top prospects in baseball based on his potential ability to be an all-around contributor. While he has shown some speed and some strong defense at times, he has been consistently subpar at the plate.
From his 2022 debut to the present, Thomas has now stepped to the plate 915 times at the major league level. He has 20 home runs in that time but his 5.2% walk rate is a few ticks below average and his overall batting line of .226/.271/.359 translates to a wRC+ of 71, indicating he’s been 29% worse than league average overall. That includes a .191/.248/.362 line and 67 wRC+ here in 2024.
Thomas has some encouraging signs on his Statcast page in terms of how hard he hits the ball, so it might seem like bad luck that he has a .261 batting average on balls in play, which is well below par. However, he’s also continually struggled to get underneath the ball, with a 57.2% ground ball rate in his career and a 60% rate here in 2024.
In previous seasons, Thomas has made up for his lack of offense by providing value in center field, but that hasn’t been the case this year. He came into 2024 with 11 Defensive Runs Saved and 11 Outs Above Average in the outfield but both of those metrics have put a mark of -1 on him this year. Perhaps he hasn’t been fully healthy, as he spent some time on the injured list due to a left hamstring strain and his sprint speed of 27.9 feet per second is down from previous years. He was at 29.3 in 2022 and 28.8 last year.
Whether his health has played a factor or not, he’s essentially been a replacement level player this year and Jake McCarthy has forced his way into more playing time. McCarthy is hitting .311/.380/.458 this year for a wRC+ of 135 while stealing 17 bases and and getting solid marks for his outfield work. Those all-around contributions have led FanGraphs to credit him with 2.7 wins above replacement on the year already.
The Snakes have an outfield mix that consists of McCarthy, Corbin Carroll and Lourdes Gurriel Jr. with Joc Pederson in the designated hitter slot most days. Randal Grichuk is often Pederson’s short-side DH platoon partner and is also capable of serving as a fourth outfielder. McCarthy has played all three outfield positions but could perhaps become the regular in center now while Thomas gets regular at-bats in Reno and tries to get in a groove down there.
He is still quite young and still has time to find himself at the plate but the Diamondbacks are trying to win now and need to put their best club on the field. They are currently 68-53 and tied with the Padres for the top National League Wild Card spot. Both clubs are also just 3.5 games behind the Dodgers in the West division.
Speaking of platoons, subbing in Alexander could help the club in that regard. Each of Thomas, Carroll, McCarthy and Pederson are lefties and all of them have notable platoon splits except for McCarthy, who has reverse splits. Alexander hits right-handed could perhaps cover third base against southpaws while Eugenio Suárez, also a righty, moves into the DH slot, allowing Grichuk to move to the outfield and perhaps shield Carroll from time to time. When Christian Walker returns from the IL and takes over at first base, the switch-hitting Josh Bell could be a factor as well. Alexander will also give the club a bit of extra cover at second while Ketel Marte is banged up with a left ankle injury.
Turning back to Thomas, the move has the potential to impact his earning power. He came into this season with one year and 132 days of service time. If he had stayed up in the majors all year, he would have gone into the offseason at 2.132 and with a very good chance at qualifying for arbitration as a Super Two player, based on past cutoffs. This year’s cutoff won’t be determined until the end of the year but each day he stays down in the minors will decrease his chances of crossing it. If he falls short of the line, he will get the usual three arbitration seasons, while getting to Super Two status would have given him a fourth chance at a salary bump.
Diamondbacks Place Jordan Montgomery On Injured List
The D-Backs shook a few things up in advance of their series with the Dodgers. Arizona reinstated catcher Gabriel Moreno from the 10-day injured list and designated backup Tucker Barnhart for assignment. (Nick Piecoro of the Arizona Republic reported those forthcoming moves over the weekend.) The Snakes placed starter Jordan Montgomery on the 15-day injured list, retroactive to June 29, on account of right knee inflammation. Arizona also optioned young infielder Blaze Alexander to Triple-A Reno. Center fielder Alek Thomas is back from the 10-day IL, while the D-Backs recalled righty Gavin Hollowell to take a spot in the bullpen.
Montgomery has had a nightmarish season. The veteran southpaw agreed to terms on a $25MM pillow contract just before Opening Day. As with fellow late signee Blake Snell, he has had significant struggles with that abbreviated ramp-up. Montgomery agreed to head to Reno for a few starts as a tune-up. He was recalled in mid-April but hasn’t found anything close to his typical form.
Over 13 starts, Montgomery carries a 6.03 ERA in 65 2/3 innings. He’s striking out a well below-average 15.1% of opposing hitters. Montgomery had punched out more than 21% of batters faced in each of the previous three seasons. He allowed fewer than four earned runs per nine in each year while combining for a 3.48 ERA over 94 starts. The average velocity on his sinker is down from its customary 93 MPH range to 91.7 MPH.
It’s impossible to know how much of Montgomery’s struggles are attributable to the unconventional start to the season. It seems fair to presume that has played some role. Whatever the primary cause, Montgomery hasn’t provided anything close to the kind of production Arizona envisioned. The D-Backs hoped he’d step in as a mid-rotation replacement after Eduardo Rodriguez suffered a Spring Training lat strain. Instead, he’s been arguably the weakest point in a starting staff that remains the team’s biggest question mark.
Arizona recently welcomed Zac Gallen back from the injured list. They’re still without Rodriguez and Merrill Kelly. Righty Brandon Pfaadt has been solid, but the D-Backs haven’t gotten much out of Slade Cecconi and Ryne Nelson. They’ll need to find a fifth starter this week, as Arizona doesn’t have another off day until the All-Star Break. That might be righty Cristian Mena. Alex Weiner of AZ Sports tweets that Mena is with the big league club in Los Angeles, though he’s not yet on the roster. Acquired from the White Sox for Dominic Fletcher over the winter, the 21-year-old Mena has a 4.90 ERA with a 24.4% strikeout rate in 16 Triple-A starts. Joe Mantiply will kick off a bullpen game tonight; Montgomery had been slated to start tomorrow’s contest.
On the position player side, Moreno and Thomas draw back into the lineup. The former had a minimal IL stay with a thumb sprain. He’ll return to his role as the primary catcher. Barnhart’s DFA means the D-Backs will stick with José Herrera in the #2 catching role. Thomas has missed the bulk of the season because of a hamstring strain. He played in only four games before going down. That pushed Corbin Carroll into center field. Carroll should move back to right field, which could cut into the playing time for Jake McCarthy and Randal Grichuk.
It pushes Alexander off the MLB roster for the time being. The 25-year-old logged a good chunk of playing time at shortstop while Geraldo Perdomo was on the shelf. Upon Perdomo’s return, manager Torey Lovullo suggested he’d get Alexander more playing time at third base while cutting into Eugenio Suárez’s workload. Alexander got regular run for about two weeks but fell into a slump, hitting .138 without an extra-base knock in 33 plate appearances. Suárez has started five of the past six games at the hot corner. With Kevin Newman playing reasonably well as a utility option who cannot be optioned, the D-Backs send Alexander back to Reno for more consistent playing time.
NL West Notes: Rodriguez, Thomas, Musgrove, Montgomery
The Diamondbacks sent both left-hander Eduardo Rodriguez and outfielder Alek Thomas for MRI exams last week, and Torey Lovullo told reporters (per MLB.com’s Injury Tracker) that the results of Rodriguez’s MRI were “very positive,” but that there was no update on Thomas’s status as the club plans to seek second and third opinions on the youngster’s results.
It’s excellent news for the Diamondbacks that Rodriguez is making his way toward a return, with Lovullo indicating that he’s set to begin a throwing program. Rodriguez will be sidelined through at least May 24 due to his placement on the 60-day injured list but it’s at least feasible he could return to game action not long after that if he manages to avoid further setbacks. Rodriguez’s lat injury woes have prevented him from making his Dbacks debut to this point in the 2024 campaign, but he’s coming off an excellent season with the Tigers last year that saw him post a 3.30 ERA and 3.66 FIP in 152 2/3 innings of work and should provide a major boost to an Arizona rotation that’s currently relying on Ryne Nelson and Slade Cecconi in the absence of Rodriguez and veteran righty Merrill Kelly.
As for Thomas, the lack of update from the Diamondbacks is a somewhat ominous sign regarding his hamstring. The 24-year-old was initially scheduled to be activated from the IL last week but ended up exiting a rehab outing with Triple-A due to an issue with his injured hamstring on May 5 that ultimately did not improve after a day off, prompting Arizona to delay his return and send him for testing. Once a consensus top-30 prospect in the sport, Thomas has struggled at the big league level with a .230/.273/.362 slash line in 242 career games but nonetheless figured to be the club’s starting center fielder this season. Corbin Carroll has handled center field in Thomas’s absence with Jake McCarthy stepping from the bench into Thomas’s spot in the lineup while manning right field.
More from the NL West…
- Padres right-hander Joe Musgrove is making good progress in his return from right elbow inflammation, according to manager Mike Shildt (per MLB.com’s Injury Tracker). The 31-year-old’s initial worrisome diagnosis was described as “precautionary” when he was initially placed on the shelf last week, and it appears that description was an apt one as Musgrove has reportedly already begun light baseball activities, including playing catch. MLB.com writes that the right-hander is optimistic that he’ll be able to return “shortly after” the minimum 15-day stint on the IL, which would likely result in him returning to action sometime next week. San Diego is surely hoping that Musgrove will look more like the ace hurler who posted a 3.05 ERA in 459 2/3 innings in a Padres uniform entering the 2024 campaign than he has to this point in the season, as he struggled badly with a 6.37 ERA and 5.96 FIP in eight starts prior to his placement on the shelf.
- The Rockies may have lost outfield prospect Benny Montgomery for the season on Friday, as MLB.com’s Thomas Harding relays that the 21-year-old underwent shoulder surgery that Rockies director of player development Chris Forbes said will keep him out until at least “toward the end of the year” if he’s able to return this season at all. The club’s first-round pick in the 2021 draft, Montgomery turned heads during the Arizona Fall League last year with a .333/.436/.500 slash line in 19 games and was hitting a solid .283/.313/.500 in his first taste of Double-A action before being sidelined by the shoulder injury.
