Diamondbacks Rumors

Diamondbacks Reinstate Ketel Marte

By Connor Byrne | May 19, 2021 at 5:43pm CDT

The Diamondbacks announced that they have reinstated Ketel Marte from the 10-day injured list and optioned outfielder Nick Heath to Triple-A Reno.

Arizona has gone almost the entire season without Marte, who landed on the IL on April 8 with a right hamstring strain. The 27-year-old began the season as the Diamondbacks’ No. 1 choice in center field, and they’ve since left the position to a combination of Heath, Tim Locastro, Pavin Smith and Daulton Varsho. D-backs center fielders rank a below-average 23rd in fWAR (minus-0.2) and 24th in wRC+ (80).

Marte, 27, was red hot to begin the campaign, as he slashed .462/.500/.846 with two home runs in 28 plate appearances. That was more like the MVP-contending Marte the Diamondbacks saw in 2019, not the one who hit .287/.323/.409 with two homers in 195 PA last year.

D-backs To Promote Corbin Martin, Place Luke Weaver On Injured List

By Steve Adams | May 18, 2021 at 12:06pm CDT

The Diamondbacks will place right-hander Luke Weaver on the 10-day injured list following his recent shoulder discomfort and call up right-hander Corbin Martin to make his team debut in one of the remaining games of this four-game set against the Dodgers, John Gambadoro of Arizona Sports 98.7 FM reports (via Twitter).

Weaver, 27, exited his most recent outing with shoulder discomfort but expressed optimism after the fact that he could remedy the issue with a change to his mechanics. At the time the righty was optimistic that he’d avoid the injured list, but Gambadoro indicates that Weaver won’t make his scheduled start against the Rockies on Friday and is indeed IL-bound.

Acquired from the Cardinals as part of the Paul Goldschmidt trade, Weaver had an up-and-down season so far, sandwiching four ineffective starts between four pretty strong outings — two on either end of that rough stretch. Overall, the former first-rounder has a 4.50 ERA through 40 innings with a slightly below-average 22.8 percent strikeout rate but a better-than-average 7.8 percent walk rate. He’ll join Zac Gallen and Taylor Widener on an increasingly crowded D-backs injured list that also currently holds position players Ketel Marte, Asdrubal Cabrera, Christian Walker, Carson Kelly and Kole Calhoun.

Turning to the 25-year-old Martin, his promotion is of plenty note for the D-backs, who thought highly enough of the 2017 second-rounder to make him one of the key pieces they received from the Astros in return for Zack Greinke. Martin was on the injured list at the time, having undergone Tommy John surgery earlier in the 2019 season, but he entered that year regarded as one of the game’s 100 best prospects, ranking 78th at Baseball America and 81st at MLB.com. Eric Longenhagen of FanGraphs currently ranks Martin as the D-backs’ No. 6 prospect and the No. 114 prospect in baseball.

Martin did get his feet wet with the ’Stros before falling to that UCL injury, albeit in a small sample of 19 2/3 innings. He was roughed up for 14 runs in that time (two unearned), but his prospect pedigree and excellent minor league track record give plenty of hope that he can eventually be a big piece of the Arizona staff. He’s tossed 9 2/3 innings in Triple-A Reno this year and yielded only two runs with a 14-to-6 K/BB ratio.

The 2019 injury, the canceled 2020 minor league season and the delayed 2021 minor league campaign have all combined to limit Martin to a total of 201 2/3 innings in the minors, but he’s excelled at every level. The righty carries a career 2.54 ERA, a strong 27.8 percent strikeout rate, an 8.4 percent walk rate and a hearty 53.2 percent grounder rate in that time. He’s been as effective in Triple-A as he was in Double-A, logging a 2.87 ERA with 59 punchouts in 47 innings, although his 24 walks at that level are a bit more troubling. That’s the only level at which Martin has struggled with free passes, though, and scouting reports generally give him credit for average or above-average command.

Given last year’s lack of innings and the fact that he’s working back from major elbow surgery, Martin will probably see his workload managed rather judiciously in 2021. Still, his promotion gives the D-backs and their fans a first glimpse at a pitcher the club hopes can be a prominent contributor to the starting staff for the foreseeable future. If he sticks on the MLB roster this year, the D-backs would control him all the way through the 2025 season, but future optional assignments could push his free agency back even further.

NL West Notes: Dickerson, Belt, Taylor, Weaver, Marte

By Mark Polishuk | May 16, 2021 at 7:46pm CDT

The Giants activated outfielder Alex Dickerson off the 10-day injured list prior to today’s game with the Pirates, and Dickerson went 1-for-5 with a single in the 4-1 San Francisco victory. Dickerson only missed the minimum 10 days while recovering from a right shoulder impingement, and he’ll look to get on track at the plate after hitting only .213/.276/.338 over his first 87 plate appearances. Dickerson was a much more productive hitter in 2019-20, batting a somewhat under-the-radar .286/.350/.529 in 360 PA, all but 19 of which came in a Giants uniform.

Dickerson’s return could help a lineup hampered by the continued absence of Brandon Belt, who was a late scratch for today’s game. Belt left Tuesday’s game due to left side tightness and has made only two appearances since (one as a starter, and one as a pinch-hitter). It’s possible an IL stint might be necessary for Belt, who has impressed with a .233/.360/.495 slash line and eight home runs in his first 125 PA of the season.

Rays Acquire Wyatt Mathisen From Diamondbacks

By Mark Polishuk | May 16, 2021 at 5:06pm CDT

The Rays have acquired utilityman Wyatt Mathisen from the Diamondbacks, with cash considerations heading back Arizona’s way. Mathisen was designated for assignment by the D’Backs earlier this week, and he will report to Tampa Bay’s Triple-A affiliate.

The 29-year-old Mathisen made his MLB debut last season with Arizona, and over 32 games and 84 plate appearances in 2020-21, Mathisen has hit .159/.298/.290. He has also seen time at both corner infield positions and in left field.

Third base has been Mathisen’s primary position over 649 games in his minor league career. Initially breaking into the pros as a catcher when he was a second-round pick for the Pirates in the 2012 draft, Mathisen hasn’t been behind the plate since 2013, moving on to play mostly third base but also a lot of time at first and second. The outfield work is a relatively new part of his defensive arsenal, as Mathisen hadn’t played outside the infield until 2019.

With a .272/.360/.396 slash line over 2507 PA in the minors, Mathisen has shown some decent on-base skill, and he’ll add yet another multi-position weapon to the Rays’ stash of versatile players. Yandy Diaz, Mike Brosseau, and Kevin Padlo are all on the big league roster and are all right-handed hitters who can play corner infield roles, so Mathisen may have to wait until circumstances change for his next call-up to the Show.

Diamondbacks Place Kelly, Bukauskas, Devenski On Injured List

By Mark Polishuk | May 16, 2021 at 4:07pm CDT

MAY 16: “All options,” including surgery, are a possibility for Devenski, Lovullo said this afternoon (via Zach Buchanan of the Athletic).

MAY 15, 7:05PM: Right-hander Chris Devenski has also been sidelined, as the D’Backs announced that Devenski is headed to the 60-day injured list due to a sprained right UCL. Left-hander Joe Mantiply’s contract has been selected from Triple-A to take Devenski’s place on both the active roster and 40-man roster.

MAY 15, 6:49PM: Both Kelly and manager Torey Lovullo told reporters (including MLB.com’s Jake Rill) that they’re hopeful Kelly will be able to return shortly after his 10-day minimum absence.

MAY 15, 5:48PM: The Diamondbacks announced that catcher Carson Kelly and righty J.B. Bukauskas have been placed on the 10-day injured list. Kelly is suffering from a tuft fracture in his big left toe, while Bukauskas has a right elbow flexor strain. In corresponding moves, right-hander Yoan Lopez was called up from Triple-A and infielder Domingo Leyba’s contract was selected from Triple-A. To create a 40-man roster spot for Leyba, Kole Calhoun was moved to the 60-day IL.

It’s another damaging injury blow to an Arizona team that has placed Zac Gallen, Christian Walker, and Asdrubal Cabrera on the IL just in the last few days, and the D’Backs have already been without Calhoun and Ketel Marte for the majority of the season.

Kelly’s loss is particularly tough, as the catcher has hit a scorching .338/.491/.613 over his first 110 plate appearances of the season. While Kelly has enjoyed some BABIP luck (.344) and isn’t posting memorable hard-hit ball numbers, he is also doing an outstanding job at getting on base and making contact. Kelly’s .491 OBP leads the National League, and he has more walks (23) than strikeouts (16).

Depending on the severity of the fracture, Kelly’s absence could either be relatively short or rather lengthy. Stephen Vogt could now assume starting catching duties with Kelly out, or the D’Backs could explore giving top prospect Daulton Varsho more of a look behind the plate. Since making his MLB debut last season, Varsho has made 11 total appearances at catcher, but he has only played the position once in 2021. Given Varsho’s ability to play the outfield, the Diamondbacks could more or less split his playing time between catcher and outfield whenever Vogt needs a break.

Bukauskas made his Major League debut this season, and has posted an 8.31 ERA out of Arizona’s bullpen over his first 8 2/3 innings in the Show. While the righty has given up a lot of hard contact, his ERA isn’t quite indicative of how he has pitched — Bukauskas has a much more respectable 3.64 SIERA, as he has been hampered by an abnormally low 54.8% strand rate and an abnormally high .433 BABIP. Bukauskas the 15th overall pick of the 2017 draft, and was sent to the D’Backs from the Astros as part of the Zack Grienke trade in 2019.

Leyba was also a trade pickup for Arizona, coming to the organization from the Tigers along with Robbie Ray as part of the three-team trade in 2014 that saw Shane Greene go to Detroit and Didi Gregorius to the Yankees. Leyba made a solid accounting of him by hitting .280/.367/.440 in 30 PA during his 2019 rookie season, but missed all of 2020 due to an 80-game PED suspension.

Leyba has plenty of experience as a shortstop, second baseman, and third baseman, so he represents a versatile asset for the Diamondbacks as they figure out how to juggle their roster amidst all these injuries. Speculatively, Leyba could provide infield depth if Josh Rojas sees more time in the outfield on account of Varsho getting more catching starts.

D’Backs Prospect Corbin Carroll To Miss Rest Of 2021 Season

By Mark Polishuk | May 15, 2021 at 8:02pm CDT

Diamondbacks outfield prospect Corbin Carroll will undergo shoulder surgery that will keep him out of action for the remainder of the 2021 season, MLB Pipeline’s William Boor reports. The Athletic’s Zach Buchanan (via Twitter) adds the detail that Carroll injured his shoulder while hitting a home run — presumably the solo homer Carroll hit on May 10, in his last game with the high-A level Hillsboro Hops.

Selected with the 16th overall pick of the 2019 draft, Carroll has hit .316/.428/.542 over his first 215 plate appearances in pro ball. Between this injury and the canceled 2020 minor league season, Carroll will lose two critical years of development, though Buchanan notes that the 20-year-old Carroll was seen as being “already ahead of the curve.”

Carroll is the consensus pick as the top prospect in Arizona’s farm system, and one of the better minor leaguers in all of baseball. Fangraphs ranks him 20th on their top prospects list, and Carroll also has high finishes on top-100 rankings from Keith Law (23rd), Baseball America (34th) and MLB.com (38th).

Carroll is already considered to be big league-ready as a center field-capable defender and a baserunner with 70-grade speed, and is seen as a future leadoff man due to his on-base skills and contact-oriented approach at the plate. “So exceptional are Carroll’s hand-eye coordination and barrel accuracy, especially for his age, that he now has among the best hit tool projections in the minors,” according to Fangraphs’ scouting report.

Diamondbacks Place Zac Gallen, Christian Walker On 10-Day IL

By Connor Byrne | May 12, 2021 at 5:46pm CDT

5:46pm: Early test results on Gallen’s elbow have been “encouraging,” Bob Nightengale of USA Today tweets.

5:02pm: The Diamondbacks have placed right-hander Zac Gallen (elbow sprain) and first baseman Christian Walker (right oblique soreness) on the 10-day injured list, Nick Piecoro of the Arizona Republic reports. The team also selected righty Seth Frankoff, recalled infielder Andrew Young and designated infielder/outfielder Wyatt Mathisen for assignment.

Gallen was supposed to start Wednesday against his former team, the Marlins, but he’ll instead be out for a while longer. He’s dealing with a “minor sprain of one section of his UCL in his right elbow,” according to manager Torey Lovullo, who added that the team will “reassess in a couple weeks” (via Piecoro). If the issue is anything but “minor,” it would be a terrible development for Gallen and the D-backs, as the 25-year-old has thrived since they acquired him from Miami for second baseman Jazz Chisholm in 2019.

Chisholm has turned into a valuable player in his own right since the deal went down, but Arizona’s surely pleased with Gallen’s output in its uniform. Gallen owns a 2.85 ERA in 142 1/3 innings as a Diamondback, including a 3.04 mark over 26 2/3 frames this year, and has posted a 28.4 percent strikeout rate against a 9.7 percent walk rate.

This is the second IL placement of the year for Walker, who has landed on the shelf both times because of his oblique. Even when healthy enough to play this season, Walker has fallen well short of the above-average numbers he registered from 2019-20, having hit a disappointing .203/.268/.313 through 71 plate appearances.

Mathisen has joined Walker in seeing time at first base for the Diamondbacks, who will have a week to trade the 27-year-old or get him through waivers. Mathisen has been tremendous at the Triple-A level, where he has slashed .267/.370/.514 with 32 home runs in 627 trips to the plate. However, that success hasn’t translated to the majors, as Mathisen has batted .159/.298/.290 over a much smaller sample size of 84 plate appearances. Mathisen has two minor league options left, so perhaps a team seeking offensive depth will take a chance on him.

Frankoff, 32, signed a minor league deal with the Diamondbacks last winter after the Mariners outrighted him. He had a productive run with the Korea Baseball Organization’s Doosan Bears from 2018-19, during which he combined for a 3.68 ERA in 266 2/3 frames. Prior to that, almost all of his career was spent in the minors with the Athletics, Dodgers and Cubs. Frankoff only has 4 2/3 big league innings under his belt.

Cubs Acquire Trayce Thompson

By Connor Byrne | May 11, 2021 at 8:37pm CDT

The Cubs have acquired outfielder Trayce Thompson from the Diamondbacks for cash considerations, per Tommy Birch of the Des Moines Register. Thompson is now with Triple-A Iowa.

Thompson began his professional career with another Chicago organization – the White Sox – who chose him in the second round of the 2009 draft. He climbed to the majors in 2015 and wowed over 135 plate appearances with a .295/.363/.533 line and five home runs, though that wasn’t enough for the White Sox to keep him in the fold. In the ensuing offseason, they traded Thompson to the Dodgers in a three-team deal that also involved the Reds and featured some other notable names (including Todd Frazier, Frankie Montas and Scott Schebler).

Now 30 years old, Thompson hasn’t been able to replicate the success he had during his initial MLB action. His time with the Dodgers ran out after two seasons, and he most recently appeared in the majors in 2018 with the Athletics and his first team, the White Sox. In all, Thompson has amassed 589 plate appearances at the game’s highest level and batted .206/.276/.389 with 22 home runs. Thompson has posted fairly similar numbers in Triple-A, where he has hit .229/.288/.417 with 50 long balls in 1,373 PA.

Health Notes: Ohtani, Mondesi, Graterol, Mikolas, D-backs,

By Connor Byrne | May 3, 2021 at 9:05pm CDT

Right-hander Shohei Ohtani was supposed to take the mound for the Angels in their game against the Rays on Monday, but the team scratched him in favor of lefty Jose Quintana because of elbow soreness. Ohtani swas hit by pitch on Sunday, and manager Joe Maddon told reporters (including Mike DiGiovanna of the Los Angeles Times) that he’s now “too sore to throw.” However, there’s still a chance he’ll start sometime during this four-game set versus Tampa Bay. Even if that doesn’t happen, Ohtani feels well enough to hit, so the DH will continue making an offensive impact. Ohtani has only made three starts and pitched 13 2/3 innings this season, but he has overcome control problems (13 walks) to log a 3.29 ERA with 23 strikeouts and a 62.5 percent groundball percentage. He has complemented his pitching performance with a power-packed .270/.318/.620 line, eight homers and six stolen bases over 107 plate appearances as a hitter.

Royals shortstop Adalberto Mondesi will start doing pregame work with the team this week and could begin a rehab assignment next week, per general manager Dayton Moore (via Anne Rogers of MLB.com). The Royals have gone all season without Mondesi, the reigning stolen base champion who strained his right oblique during the spring. Despite Mondesi’s absence, the Royals entered Monday with a surprising 16-10 record – the best mark in the majors. Nicky Lopez has filled in capably for Mondesi during KC’s fast start.
Dodgers reliever Brusdar Graterol will undergo an MRI on his ailing right forearm Tuesday, Jorge Castillo of the Los Angeles Times tweets. The team placed Graterol on the IL last Thursday with forearm tightness – a rather ominous-sounding injury for someone who underwent Tommy John surgery in the past – and the 22-year-old hasn’t resumed throwing since then, according to Castillo. The Dodgers lost another of their promising young hurlers, righty starter Dustin May, to the dreaded TJ diagnosis on Monday.
Cardinals righty Miles Mikolas will make a rehab start with Triple-A Memphis this week, and he’ll “likely” go four innings, Jeff Jones of the Belleville News-Democrat writes. Mikolas hasn’t pitched in the majors this year because of shoulder problems, after he sat out all of last season on account of flexor tendon surgery. His most recent MLB outing occurred Oct. 11, 2019.
The Diamondbacks have reinstated first baseman Christian Walker and outfielder Tim Locastro from the IL, Nick Piecoro of the Arizona Republic tweets. The club optioned outfielder Nick Heath and infielder Andrew Young in corresponding moves. The Diamondbacks have been without Walker since April 12 because of a right oblique strain, while Locastro suffered a dislocated finger April 17. Walker had a rough go early on with a .179/.250/.282 line and one homer in 44 trips to the plate. Locastro, meantime, took 58 PA last month and batted .269/.345/.327 with an HR and three steals.

Kole Calhoun Undergoes Hamstring Surgery

By Connor Byrne | April 30, 2021 at 5:33pm CDT

APRIL 30: Calhoun underwent surgery on his hamstring, Zach Buchanan of The Athletic tweets. He could miss six to eight weeks, general manager Mike Hazen announced (via Steve Gilbert of MLB.com).

APRIL 28: The Diamondbacks announced that they have placed outfielder Kole Calhoun and right-hander Taylor Widener on the 10-day injured list. They recalled catcher/outfielder Daulton Varsho and righty Riley Smith to fill the empty roster spots.

Calhoun suffered a left hamstring strain during the Diamondbacks’ win over the Padres on Tuesday, forcing him to leave early. This will already be the second IL stint of 2021 for Calhoun, who was unavailable to start the season after undergoing surgery on a torn right meniscus. Calhoun, who’s in the last season of a two-year, $16MM guarantee, has been one of Arizona’s top hitters since he joined the team. The ex-Angel had an impressive 2020 and has continued to fare well this season with a .292/.333/.479 line and a pair of home runs in 51 plate appearances.

Calhoun’s injury creates another opportunity for the 24-year-old Varsho, whom Baseball America ranks as the sport’s 60th-best prospect. Varsho, the 68th pick in the 2017 draft, debuted in the majors last year and batted .188/.277/.368 with three homers over 115 trips to the plate. He was far more productive during his most recent minor league action in 2019, when he slashed .301/.378/.520 with 18 HRs and 21 steals across 452 PA.

Widener’s heading to the shelf with a right groin strain, retroactive to April 25. The 26-year-old is tied for second on the Diamondbacks in starts (four) this season and has pitched to a 2.82 ERA with a 6.5 percent walk rate through 22 1/3 innings. However, Widener’s fielding-independent numbers – including a 4.52 SIERA, 4.73 FIP and 4.75 xFIP – aren’t as encouraging. Smith will start in Widener’s place Wednesday against the Padres.
