- Mariners star Julio Rodriguez moved down to the sixth spot in the batting order in yesterday’s game against the Rangers, marking the first time this season the young outfielder batted outside of the leadoff spot. Manager Scott Servais told reporters, including The Athletic’s Corey Brock, that the move was designed to take pressure off of last year’s AL Rookie of the Year, who has scuffled to a .205/.270/.384 slash line, good for a wRC+ of just 85. Rodriguez, for his part, expressed support for the decision, noting that he believed it was the best thing for the team.
Mariners Rumors
Mariners’ Offseason Trade Acquisitions Off To Slow Starts
The Mariners mostly shied away from the free agent market on the heels of their drought-ending playoff berth. Instead, Seattle turned to trade to add to a lineup that had been a bit top-heavy in 2022. Their two most notable transactions took place within the first few weeks of the offseason: reliever Erik Swanson and pitching prospect Adam Macko were shipped to Toronto for slugger Teoscar Hernández, while the M’s dealt Jesse Winker and Abraham Toro to the Brewers for second baseman Kolten Wong.
Both Hernández and Wong are in their final seasons before free agency. Milwaukee had exercised a $10MM club option on Wong before trading him in what amounted to a roughly cash-neutral deal considering they took back Winker’s salary. Seattle took on a decent chunk of 2023 money to accommodate Hernández, who’d earn $14MM for his final season of arbitration eligibility (compared to the $1.25MM Swanson is making in his first of three arbitration years).
Hernández, in particular, could eventually net the club a compensatory draft choice by rejecting a qualifying offer and signing elsewhere next offseason. Yet both trades were primarily about bolstering the lineup in 2023 while avoiding the longer-term downside associated with a multi-year free agent deal.
To this point, neither player has met Seattle’s expectations. Hernández is sitting on a .215/.260/.396 batting line over 154 plate appearances. That’s nowhere close to the .283/.333/.519 line he’d compiled between 2020-22 to pick up a pair of Silver Slugger awards and down-ballot MVP finishes. His raw slash stats always seemed likely to dip somewhat with the move from Rogers Centre to T-Mobile Park. This has been a far more significant drop-off than is solely attributable to park factors and Hernández is performing worse on the road than he is in Seattle.
Hernández has popped seven home runs, putting him on a 27-homer pace over 600 plate appearances. He’s still barreling the ball up and making hard contact when he puts the ball in play. The middle-of-the-order form he’d shown for years in Toronto still looks to be there. Yet his plate discipline has been rough thus far, resulting in a career-worst 3.2% walk rate and a massive 35.1% strikeout percentage.
Selectivity has never been Hernández’s specialty. He’s always been an aggressive hitter, one who’s willing to trade some walks for power impact. He has pushed that too far to the extreme through his first few weeks in Seattle, though, as he’s chased nearly 40% of pitches outside the strike zone. It’s the 23rd-highest rate among 204 hitters with 100+ plate appearances; Hernández was closer to league average in that regard during his last few seasons in Toronto.
Wong, meanwhile, has been one of the least effective hitters in the majors to this point. He’s yet to connect on a homer in 94 trips to the plate, posting a .195/.287/.220 line overall. He has played well through his first five games in May after carrying a .171/.263/.186 slash through the end of April. The Mariners weren’t counting on Wong to be an impact bat but surely hoped for something approximating the solid .262/.337/.439 showing he put together over two years in Milwaukee.
The lefty-hitting Wong has long been a quality, well-rounded regular. He’s typically hit around a league average level, compensating for fringe power with plus contact skills. At his peak, he’s been a Gold Glove second baseman and a plus baserunner. His typically stellar defensive marks dropped off during his last season with the Brewers, as both Defensive Runs Saved and Statcast’s Outs Above Average gave him subpar grades in 2022.
Wong attributed his defensive drop to playing through leg injuries, offering some hope he’d turn things around after an offseason of rest. The early returns haven’t been promising, however. DRS has pegged Wong as an MLB-worst eight runs below average through 226 2/3 innings of second base work; Statcast has him one run worse than expected. Public defensive metrics can be wildly variable in small samples, but it’s a discouraging start for the 32-year-old’s efforts to recapture his formerly excellent form with the glove.
Without many early contributions from Hernández or Wong, Seattle’s position player group hasn’t been especially good. They’re 22nd in runs scored (157) and 25th in both on-base percentage (.302) and slugging (.372). After accounting for their pitcher-friendly ballpark, they’re 19th in offensive production as measured by wRC+. Their pitching and defense has kept them around average overall — they’re in fourth place in the AL West at 18-19 with a +14 run differential — but they’ll need more out of the lineup to earn a repeat playoff berth in an American League playoff mix that has 10 to 12 teams with realistic aspirations.
There’s certainly time for Seattle’s top offseason acquisitions to get things back on track. The M’s have by no means played themselves out of contention. Whether they make a serious run for the division and/or a Wild Card spot could be determined in large part by how quickly Hernández and Wong find their previous levels. With both players headed to the open market six months from now, their free agent outlooks are also to be determined based on their performances this summer.
Evan White To Undergo Hip Surgery
Mariners first baseman Evan White will undergo another procedure on his left hip, the team informed reporters (including Ryan Divish of the Seattle Times). The recovery estimate is three months.
White is already on the 60-day injured list. He suffered an adductor strain two games into his Triple-A season and was initially expected to miss two months. That won’t come to be, as White unfortunately is headed under the knife yet again. His 2021 campaign was cut short by the first surgery he underwent on his left hip. The former first round draftee then missed the bulk of last season due to a sports hernia surgery.
For a third consecutive year, White is now going to be sidelined by a notable procedure. The initial estimate suggests he could return sometime in August, though the organization would surely be cautious with his ramp-up based on his extensive injury history. Even in the best case scenario, he’s now set to miss the majority of the year.
White hasn’t played a big league game since 2021. A well-regarded prospect during his time climbing the minor league ranks, he stumbled to a .165/.235/.308 line in 306 MLB plate appearances between 2020-21. He’s spent the bulk of the past couple years on the injured list and has only gotten Triple-A reps when healthy enough to take the field.
The Mariners signed White to a $24MM extension before he made his big league debut. He’s making $3MM this season and due successive salaries of $7MM and $8MM over the next two years. The Mariners have a pair of club options thereafter but they’re certainly trending towards declining those given White’s various health issues.
Seattle also got unfortunate news on star reliever Andrés Muñoz. The hard-throwing righty has been out since April 8 with a deltoid strain. He’d been nearing a rehab assignment but suffered a minor setback. Divish tweets that he experienced some shoulder soreness during a recent bullpen session. The M’s sent Muñoz for an MRI, which revealed some inflammation. He received a platelet-rich plasma injection and isn’t expected to begin a minor league stint until the end of the month.
Muñoz was one of the game’s best relievers in 2022. He worked to a 2.49 ERA through 65 innings, striking out an incredible 38.7% of batters faced while keeping his walks to a solid 6% rate. That understandably earned him plenty of high-leverage looks as the season wore on, as he saved four games and held 22 more leads.
Mariners Place Penn Murfee On 15-Day Injured List
The Mariners have placed right-hander Penn Murfee on the 15-day injured list due to right elbow inflammation, according to Ryan Divish of the Seattle Times (Twitter link). Right-hander Juan Then is being called up from Double-A in the corresponding move, and Then’s first appearance will mark his MLB debut.
Murfee made his own Major League debut in 2022 and immediately contributed to Seattle’s bullpen, posting a 2.99 ERA over 69 1/3 innings. Murfee’s strikeout and walk rates were well above average, and he was one of the league’s best at inducing soft contact. The overall results have improved this season as per Murfee’s 1.38 ERA over 15 innings, except with the red flag of a drastically inflated 16.7% walk rate. A tiny .143 BABIP has certainly helped Murfee avoid much damage, though his SIERA is 4.52.
Walks have been a problem for the Mariners’ bullpen as a whole this season, even though the relief corps has still been quite solid overall. However, it isn’t good news that the M’s are now missing two notable relievers in Murfee and Andres Munoz, who has spent close to a month on the 15-day IL due to a right deltoid strain that seems to be a bit more troublesome than initially anticipated. For what it’s worth, Murfee’s elbow inflammation also seems relatively minor, as Divish tweets that the Mariners were hoping he could avoid an IL trip altogether.
Then was added to Seattle’s 40-man roster back in November, protecting righty from selection in the Rule 5 Draft. Then was an international signing for the Mariners in 2016, and after being traded to the Yankees in November 2017, was re-acquired as part of the Edwin Encarnacion trade in June 2019. Once the 2019 season was complete, things started to go sideways for Then, who (like all minor leaguers) lost the 2020 season to the pandemic, and then struggled through two injury-shortened seasons at the high-A and Double-A levels in 2021 and 2022.
MLB Pipeline ranks Then 23rd on their list of the Mariners’ top 30 prospects, noting that his performance in the Arizona Fall League merited a return to the ranking and apparently indicated that his elbow problems were behind him. Back at Double-A this season, Then has a 27.5% strikeout rate and 7.5% walk rate over nine innings of work, but also a 5.00 ERA.
To this end, promoting Then to the majors and skipping Triple-A entirely seems like an aggressive move for the Mariners, based both on results and the fact that Then has pitched only 30 total innings (counting AFL and Dominican Winter League work) since the start of the 2022 season. It could be that the M’s might be viewing Then as just a short-term add before figuring out a 40-man roster opening to accommodate another pitcher.
Mariners Release Tommy La Stella
The Mariners announced Thursday afternoon that infielder Tommy La Stella has cleared waivers and been released. He’s now a free agent.
Seattle designated the 34-year-old La Stella for assignment earlier in the week when selecting the contract of top pitching prospect Bryce Miller. He’d signed on with the team back in January after being released by the Giants ahead of the third and final season of a three-year contract, but a spring elbow injury had prevented La Stella from playing the field. He’s been limited to DH and pinch-hit duties so far, taking just 24 plate appearances in 12 games over the season’s first month. It was a curious use of a roster spot in the first place, and La Stella’s .190/.292/.238 slash in that span didn’t make the decision look any better.
La Stella was a high-end, contact-oriented utilityman with the Cubs, Angels and A’s from 2016-20, batting a combined .282/.358/.435 in 1061 plate appearances and walking at nearly as high a clip as he struck out (9.6% vs. 10.6%). That strong run helped him land a three-year, $18.75MM deal with the Giants, but things didn’t pan out for La Stella either in San Francisco. His .250/.308/.405 line in 242 plate appearances in 2021 was at least passable, but a hamstring tear limited him to just 76 games. The following season saw La Stella miss time with Achilles and neck injuries, batting just .239/.282/.350 in 195 plate appearances between stints on the injured list.
Health troubles have mounted for La Stella in recent years, but given his track record, contact skills and ability to play multiple positions, another club could still show some interest. He’ll likely need to settle for a minor league deal at this point, particularly since it’s not fully clear when he might again be an option to play defense on a regular basis.
Robbie Ray Undergoes Tommy John Surgery
The Mariners provided an update today on left-hander Robbie Ray, who was reported last week to require season-ending flexor tendon surgery. “Ray, 31, had surgery today on his left elbow,” the press release reads. “The surgery was performed by Dr. Keith Meister at TMI Sports Medicine in Arlington, Texas. Dr. Meister performed a flexor tendon repair and reconstructed the Ulnar Collateral Ligament (UCL) in Ray’s left arm.” The flexor tendon surgery was already reported upon but the UCL reconstruction, also known as Tommy John surgery, wasn’t publicly known prior to today.
In the short term, this news doesn’t change much for the Mariners, as they’ve already been planning on operating without Ray for the remainder of the year. But since TJS typically requires a recovery period of 14 to 18 months, this update seems to indicate the club will be without Ray for even longer, likely a few months into the 2024 season as well.
That’s obviously unwelcome news, as Ray has been one of the better pitchers in the league in recent seasons. After some inconsistency earlier in his career, he had a tremendous season with the Blue Jays in 2021. He posted an ERA of 2.84 in 32 starts with a 32.1% strikeout rate, 6.7% walk rate and 37.2% ground ball rate. He won the American League Cy Young award and parlayed that performance into a five-year, $115MM deal with the Mariners.
His first year with Seattle was a bit of a drop-off from the previous season but still with plenty to like. He made 32 starts with a 3.71 ERA, striking out 27.4% of opponents, walking 8% and getting grounders at a 39.2% clip. That helped the Mariners break their postseason drought, making it into the playoffs for the first time since 2001. Unfortunately, he was only able to make a single start this year before landing on the injured list and likely won’t make another until midway through 2024.
The Mariners should still have a strong front four in the rotation between now and then as long as everyone is healthy. Luis Castillo and Marco Gonzales are both still under contract next year while both George Kirby and Logan Gilbert are still many years from qualifying for free agency. The final spot is a little less certain since Chris Flexen has been struggling and is slated for free agency after this season anyway. Prospect Bryce Miller was called up recently to start an audition and Ryan Divish of The Seattle Times reported that it wasn’t going to be just a spot start. That was before Miller debuted and tossed six innings against the A’s, allowing just one earned run on two hits and no walks while striking out 10. It’s best not to read too much into just one game, but given that the club planned on giving him a lengthy stay in the rotation anyway and he dominated his first time out, he seems to have a legitimate chance at securing a rotation spot going forward.
Mariners Designate Tommy La Stella For Assignment
The Mariners announced that infielder Tommy La Stella has been designated for assignment. His roster spot will go to pitching prospect Bryce Miller, whose promotion was reported yesterday.
Seattle signed La Stella in January. That came on the heels of his release from the Giants, with whom he’d signed a three-year free agent deal over the 2020-21 offseason. La Stella’s two seasons in San Francisco didn’t go well. He hit .245/.297/.380 and was limited to 136 games over that stretch by injuries. The Giants moved on, eating the $11.5MM he’s due in 2023.
Once La Stella cleared release waivers, other teams could add him for the league minimum salary. The Mariners jumped on the opportunity, hoping he’d add a productive left-handed bat to their infield mix. That didn’t pan out, as the 10-year MLB veteran had a tough showing in 12 games. He hit .190/.292/.238 with only one extra-base hit (a double) in 24 plate appearances. La Stella didn’t see any action on defense; he started six games at designated hitter and came off the bench to pinch hit on six more occasions.
With the club apparently reluctant to push La Stella into much or any defensive work, there was plenty of pressure on him to start well offensively. He didn’t come out of the gate strong and is now designated for assignment for the second time in five months. The M’s will have a week to trade him or put him on waivers; in all likelihood, he’ll be released and hit free agency within the next few days.
Once he gets to the open market, La Stella will again have the opportunity to explore his options around the league. The Giants remain on the hook for the bulk of his salary. He’d be an affordable pickup for another club that thinks there’s some offensive ability still in the tank. It’s possible he’s limited to minor league offers this time around but he still brings a high-contact bat with good awareness of the strike zone.
Mariners To Outright Diego Castillo, Promote Bryce Miller
The Mariners are shuffling up their pitching staff. They’re set to select the contract of top pitching prospect Bryce Miller, as first reported by Joe Doyle of Future Star Series, and they’ve also passed right-hander Diego Castillo through waivers and assigned him outright to Triple-A Tacoma, per Ryan Divish of the Seattle Times (Twitter link).
With that outright, Castillo is no longer on the 40-man roster. He has the three years of service time needed to reject the assignment in favor of free agency, but he doesn’t yet have five years of service, so rejecting the assignment would mean forfeiting the remainder of this year’s $2.95MM salary. As such, he’s sure to accept an assignment to Tacoma and remain with the organization.
It’s been a swift decline for Castillo, who was one of the top relievers moved at the 2021 deadline, going from Tampa Bay to Seattle in exchange for minor league infielder Austin Shenton and righty JT Chargois. Castillo was quite effective in his first season and a half with the Mariners, pitching to a 3.42 ERA with an above-average 25.5% strikeout rate against a slightly below-average 9.4% walk rate. He held opponents to just a .196 average, yielded only 1.06 HR/9 and kept the ball on the ground at a 48.5% clip.
The 2023 season, however, has been a disaster for the 29-year-old Castillo. In 8 2/3 innings so far, he’s walked as many batters as he’s fanned (seven) and also plunked a hitter. He’s already served up homers to two of the 41 batters he’s faced after surrendering only five in 54 1/3 innings (222 batters faced) a year ago. The 94.2 mph average on his fastball, meanwhile, is down 1.6 mph from last year’s mark of 95.8. Overall, he’s sitting on a 6.23 ERA and has allowed 15 of 41 opponents (.366) to reach base.
Any other team could’ve claimed Castillo, but it’s generally rare for other clubs to claim struggling players of this nature when they have a guaranteed contract of some note. The Mariners could’ve waited to make this move but likely saw Castillo’s struggles as a way to open a 40-man roster spot to accommodate their top pitching prospect. If another club had claimed Castillo, the Mariners would’ve been spared the remaining $2.44MM of this year’s salary, but they’ll instead hope he can round back into form with the Rainiers.
Turning to Miller, he’ll make his big league debut when he takes the mound tomorrow against the A’s. He last pitched on April 25, so he’ll be plenty rested. The 24-year-old has had a rough start to his 2023 season in Double-A, pitching to a 6.41 ERA in 19 2/3 frames, but he entered the year among the top 100 prospects at Baseball America, FanGraphs and MLB.com. He currently ranks 92nd, 89th and 85th, respectively on those three lists.
The handful of shaky outings to begin the year, it seems, won’t dissuade the Mariners from hoping he can follow Logan Gilbert and George Kirby to be the next member of the team’s vaunted farm system to step into the Major League rotation. Seattle has already lost Robbie Ray for the season and has seen Chris Flexen struggle in the fifth spot of the rotation, so it stands to reason that Miller could potentially seize a permanent job, if not tomorrow then certainly at some point this season.
Despite his rocky start to the 2023 season, Miller is seen as a potential mid-rotation starter, thanks in no small part to a heater that sits upper-90s and can bump 100 mph. He pairs that with a slider and changeup, and the former college reliever has improved his command as the Mariners have stretched him back out as a starter.
Miller split the bulk of the 2022 season between High-A and Double-A, logging a combined 3.16 ERA with a 30% strikeout rate and an 8.5% walk rate in 133 2/3 innings. He allowed just 0.67 HR/9 and kept the ball on the ground at a slightly above-average rate. And, given that sizable workload in ’22, there’s little reason to think the Mariners will feel the need to monitor his innings total too aggressively this season.
If Miller were to stick in the big leagues, he’d be on pace to qualify for arbitration as a Super Two player following the 2025 season and reach free agency at the conclusion of the 2029 season. Of course, future optional assignments could alter one or both of those timetables considerably.
Mariners Activate Taylor Trammell
The Mariners announced today that they have activated outfielder Taylor Trammell from the injured list, with right-hander Easton McGee headed for the 15-day IL with a right forearm strain in a corresponding move. Trammell had surgery to repair a fractured hamate bone in his right hand back in February.
A former top prospect, the 25-year old Trammell has struggled to this point in his big league career. During his first stint in the majors in 2021, Trammell slashed just .160/.256/.359 in 178 plate appearances, with a ghastly 42.1% strikeout rate. Both Trammell’s slash line and strikeout rate improved in 2022, however, has he pulled his wRC+ to nearly league average (97) in 117 plate appearances last season while striking out a more palatable 28.2% of the time. Unfortunately, Trammell’s 2022 campaign was cut short by a hamstring strain, leaving him with just 65 games played last year between the majors and Triple-A.
Despite his uneven MLB career to this point, Trammell has continued to demolish Triple-A pitching, with a phenomenal .285/.377/.495 slash line and a 20.6% strikeout rate in 101 games at the level. Now back with the big league club, Trammell figures to factor into the club’s outfield and DH mix, though with Jarred Kelenic off to a torrid start and Julio Rodriguez and Teoscar Hernandez both entrenched in the outfield on an everyday basis, Trammell may be left to compete with Sam Haggerty and AJ Pollock for DH at-bats.
Making room for Trammell on the active roster is McGee, who heads to the injured list with a forearm strain. The 25-year-old McGee made his big league debut with the Rays last season, posting three scoreless innings, but was designated for assignment by the club last offseason. He was then claimed on waivers by the Red Sox before being shipped to Seattle in exchange for Cash ahead of the 2023 campaign. McGee made his first appearance with the Mariners in a start against the Blue Jays yesterday, where he delivered 6 2/3 scoreless innings, allowing just a hit and a walk while striking out two.
Mariners Notes: Rodriguez, McGee, Flexen, Hernandez
Julio Rodriguez left today’s game due to lower back tightness, with manager Scott Servais telling reporters (including MLB.com’s Daniel Kramer) that Rodriguez started feeling discomfort after a stolen base in the third inning. The outfielder remained in the game until AJ Pollock replaced Rodriguez in center field before the bottom of the sixth, but the Mariners opted to be a little cautious with the young star.
The injury doesn’t appear to be serious, as Servais indicated that Rodriguez might potentially be back in the lineup tomorrow. However, the Mariners have an off-day on Monday before facing the A’s on Tuesday, so the team might opt to give Rodriguez “a couple days down, [so] he will be okay when we go over to Oakland,” Servais said.
As Kramer notes, Rodriguez also dealt with lower back problems near the end of the last season, which ultimately resulted in a 10-day IL placement. That decision was made in part to get Rodriguez healthy prior to the playoffs, and he was able to return just before the end of the regular season prior to hitting .217/.357/.435 over 28 plate appearances during Seattle’s postseason run.
Rodriguez’s presence might have made a difference late in today’s 1-0 loss to the Blue Jays in 10 innings. One bright spot for the M’s was the performance of surprise starter Easton McGee, who allowed just one hit and one walk over 6 2/3 scoreless innings. McGee held Toronto hitless until his final batter faced, when Matt Chapman lined a double to center field to end the unlikely no-hit bid.
Chris Flexen had initially been slated to start on Saturday, but the Mariners instead called McGee up from Triple-A prior to the game. Going into the season, Flexen was projected to work as a reliever, but a spot in the rotation opened up when Robbie Ray was sidelined with a flexor tendon injury that ended up requiring a season-ending surgery. Unfortunately for Flexen, he hasn’t risen to the occasion, with a 10.38 ERA over 17 1/3 innings in four starts as Ray’s replacement.
In addition to Monday’s off-day, the Mariners are also off on May 11 and May 18, giving the team some opportunity to reset their rotation multiple times. As a result, the M’s might only need a fifth starter twice within the next three-plus weeks. It would certainly seem like McGee has earned another look, but whether it’s McGee, Flexen, or another pitcher used as the fifth starter, the Mariners will get some time to evaluate and prepare for the longer-term question of how they’ll replace Ray.
McGee was making his first Major League start and just his second career appearance in the Show, after debuting with three innings of relief work (allowing four hits and one unearned run) as a member of the Rays in their 3-1 loss to the Astros on October 2, 2022. Tampa opted to designate McGee for assignment after that game, with the Red Sox quickly claiming the right-hander off waivers. The Mariners then acquired McGee in a trade for cash considerations in November.
A fourth-round pick for the Rays in the 2016 draft, McGee isn’t a hard thrower or much of a strikeout pitcher, with a modest 17.47% strikeout rate over 485 1/3 career innings in the minors. McGee worked to a 4.30 ERA over his minor league career by inducing a lot of grounders and avoiding walks, though his walk rate with Triple-A Tacoma this year has risen to a still-solid 7.6%. McGee largely struggled at Triple-A Durham in 2022, but he has done much better with the Mariners’ top affiliate, with a 3.14 ERA over 28 2/3 innings for Tacoma in 2023.
This weekend’s series marked Teoscar Hernandez’s first time in Toronto since the November trade that sent him from the Jays to the Mariners. Interestingly, M’s president of baseball operations Jerry Dipoto told The Athletic’s Kaitlyn McGrath and Corey Brock that Hernandez might have come to Seattle much earlier, as “most of the work we did on the Teoscar trade actually happened in Spring Training before the [2022] season began. We tried so hard to pick him up before the season started and talked through a lot of players.”
It makes for an interesting what-if, as Hernandez being dealt prior to the season might have greatly changed the trajectory for two teams that reached the postseason (and faced each other in the Wild Card Series). For Seattle, it could be that the M’s pivoted to the Eugenio Suarez/Jesse Winker trade with the Reds after not reaching an agreement with Toronto over Hernandez, or perhaps DiPoto’s front office might have even explored adding Hernandez in addition to the two former Cincinnati players. That would’ve made for a crowded outfield in Seattle, but it’s possible the Mariners might have sent one or two of those excess outfielders to the Blue Jays as part of a projected Hernandez swap. Erik Swanson may have still be part of such a trade but likely not as the primary piece, given how Swanson hadn’t yet had his 2022 breakout season, and Hernandez would’ve commanded a higher trade ask since he had two remaining years of arbitration control.
