Eric Thames Announces Retirement

Veteran first baseman and outfielder Eric Thames took to Instagram yesterday to announce his retirement. “The day has finally come,” he says in the post. “In the year of our lord, twenty, twenty-three…HE GONE! I’ve been so blessed over these last 14 years to call baseball my job. The friendships that will last a lifetime, the memories that I’ll never shut up about (and those that I’m sworn to secrecy to take to my grave ).”

This announcement officially ends one of the more unique baseball careers, as Thames has spent the past few decades crisscrossing the globe. His professional baseball life began when the Blue Jays drafted him in 2008 out of Pepperdine University. He made his major league debut with the Jays in 2011 and performed well, hitting 12 home runs in 95 games. His batting line on the year was .262/.313/.456 for a wRC+ of 107, indicating he was 7% better than the league average hitter.

Things didn’t go as well the following year, as Thames hit .243/.288/.365 for the Jays and was optioned to the minors for a time. He was then traded to the Mariners in July for Steve Delabar, getting into 40 games with Seattle after that deal. In 2013, the Mariners kept Thames in the minors and eventually designated him for assignment. He was traded to the Orioles and then went to the Astros on a waiver claim, though neither team called him up to the big leagues.

Thames signed with the NC Dinos of the Korea Baseball Organization for 2014, which transformed his career. After years of being on roster bubbles in North America, he emerged as a star in Korea. He hit 37 home runs for the Dinos that year and followed that up by hitting 47 and 40 in the next two seasons. His 2015 season stands out as being exceptionally impressive, as he also stole 40 bases and walked in 17.3% of his trips to the plate. His .381/.497/.790 batting line amounted to a 216 wRC+. He was crowned as the Most Valuable Player in the league that year.

After that strong three-year stretch with the Dinos, Thames returned to Major League Baseball, signing a three-year, $16MM deal with the Brewers. He was able to transfer a decent amount of his success from Korea to North America, as he hit 31 homers in 2017 while walking in 13.6% of his trips to the plate. His .247/.359/.518 batting line led to a 125 wRC+. Thumb surgery kept him out of action for a while in the following year, but he was still able to add another 16 home runs in 96 games, then hit another 25 in 2019. His three-year stretch in Milwaukee resulted in 72 long balls and a .241/.343/.504 batting line for a 118 wRC+. That last year saw the Brewers qualify for the Wild Card game against the Nationals. Thames went 2-4 in that game, including hitting a solo home run off Max Scherzer. But the Brewers ultimately lost 4-3 to the Nats, who would go on to win the World Series later that year, and that now goes down as the only MLB playoff game in which Thames played.

Despite that solid stretch, the Brewers surprisingly turned down a $7.5MM option on Thames for 2020 and went for the $1MM buyout instead. The Nationals scooped him up on a $4MM guarantee but he struggled in the pandemic-shortened season, hitting .203/.300/.317 with just three homers in 41 games. He signed with the Yomiuri Giants of Japan’s Nippon Professional Baseball for 2021 but suffered a ruptured Achilles tendon after just one game with the club. He tried another return to the majors in 2022 by signing a minor league deal with the A’s, but struck out in 38% of his plate appearances in Triple-A and got released after 22 games.

In the end, it makes for quite a journey, with Thames having played for baseball teams all over the world. His major league career resulted in 96 home runs, 18 stolen bases, 451 hits, 286 runs scored and 235 driven in. But he’ll perhaps be best remembered by some fans for that magical three-year run in the KBO wherein he hit 124 home runs, stole 64 bases, scored 343 runs and drove in 382.

We at MLB Trade Rumors congratulate Thames on a fascinating and distinctive career, and wish him the best in his future endeavors.

Taylor Trammell To Miss Seven-Plus Weeks Due To Hamate Surgery

Mariners outfielder Taylor Trammell will have surgery on his right hand to repair a broken hamate bone, reports Ryan Divish of The Seattle Times. Trammell will be out of action for seven or more weeks, per Corey Brock of The Athletic. Mariners president of baseball operations Jerry Dipoto tells Divish that Trammell was struck on the hand during a workout.

Trammell, 25, was once one of the most highly-touted prospects in baseball but has yet to deliver on his promise in the big leagues thus far. Originally drafted by the Reds, he has twice switched organizations in significant trades. He went to the Padres in the 2019 deal that sent Trevor Bauer to the Reds and Yasiel Puig to Cleveland, then went to the Mariners in the 2020 trade that also sent Ty France and Andrés Muñoz to Seattle.

Trammell was able to make his MLB debut in 2021 but wasn’t able to hit the ground running, striking out in 42.1% of his plate appearances. Last year, he dealt with a hamstring strain for much of the time, only getting into 43 major league contests and 22 more in Triple-A. There were some signs of optimism, as his 28.2% strikeout rate was still above average but a noticeable improvement from the year prior. He also walked in a strong 11.1% of his trips to the plate. In those Triple-A games, he only struck out 17.3% of the time and hit .333/.408/.575 for a wRC+ of 144.

The outfield in Seattle figures to be different this year compared to last. Jesse Winker was traded to the Brewers, Mitch Haniger departed via free agency and Teoscar Hernández was acquired in a trade with the Blue Jays. Hernandez and Julio Rodríguez figure to be in right and center field, respectively, but left field was open for someone like Trammell. AJ Pollock was brought signed to be the short side of a platoon but Trammell and Jarred Kelenic, who both hit left-handed, were going to be competing to be on the strong side.

Opening Day is now about six weeks away, so Trammell now seems destined to miss at least some of the regular season. That opens the possibility that Kelenic gets another stretch of time in the club’s lineup, though he has faced similar struggles. Despite hitting .302/.372/.574 in 537 Triple-A plate appearances for a wRC+ of 128, his major league batting line is .168/.251/.338 for a wRC+ of 68 in 558 trips to the plate.

Should Kelenic continue to struggle against major league pitching, it seems he’ll face another competitor in Cade Marlowe. Dipoto tells Daniel Kramer of MLB.com that Marlowe could now figure more prominently in the competition. The young outfielder, 26 in June, had a solid year at the plate last year in the minors, hitting .287/.377/.487. That amounted to a 120 wRC+ and he added 42 stolen bases to boot. Most of that came at Double-A with a 13-game stint at Triple-A to finish the season. He was added to the club’s 40-man roster in November to protect him from selection in the Rule 5 draft.

Though it’s possible Trammell doesn’t miss much of the regular season, it’s surely a frustrating start to his 2023 on a personal level after he missed so much time last year. For the club, their outfield competition has lost one option, but they will hope that one of Kelenic or Marlowe can step up.

AL Notes: Mahomes, Haggerty, Vogt, Rays

Patrick Mahomes’ ties to baseball are well known, as the NFL superstar is the son of longtime big league reliever Pat Mahomes.  However, the future Chiefs quarterback was himself a standout high school baseball player, and was even a 37th-round pick for the Tigers in the 2014 draft.  As Tigers scout Tim Grieve told 12Up’s Mark Powell in an interview in 2020, there was no doubt Mahomes was going to play college football at Texas Tech, but the Tigers figured “let’s be that team that started to build the relationship so that if he wants to play baseball 2-4 years down the road, we’ve got our foot in the door.”

Mahomes would likely have been picked in the third or fourth round of the MLB draft if he hadn’t been committed to football, and his father initially felt baseball might be his son’s sport.  “He was going to get drafted as an outfielder, and I have no doubt he would’ve made it and been successful,” the elder Mahomes told USA Today’s Bob Nightengale this week. “He loved baseball.  But when he went out for football, and saw all of the nuances and things you had to learn to be a quarterback, I think it really intrigued him to see what he could do.”  Speaking to Patrick Mahomes’ overall athletic ability, his godfather LaTroy Hawkins thought basketball would end up being his sport of choice.

Now that Mahomes has led the Chiefs to another Super Bowl title, the sports world can turn its attention to the start of Spring Training this week.  Since every season is baseball season here at MLBTR, here are some notes from around the American League…

  • “There are indications” that Mariners utilityman Sam Haggerty had to undergo surgery to fix a grade 2 adductor strain suffered at the end of last season, Ryan Divish of The Seattle Times writes.  The team hasn’t officially confirmed Haggerty’s status, and GM Jerry Dipoto that Haggerty is “a little behind” in his offseason work.  However, Dipoto also noted that Haggerty has started full baseball activity and has “been hitting for quite some time.  So he’s in a good place.”  In his fourth MLB season, Haggerty got an extended look in a utility role with Seattle last season and delivered, hitting .256/.335/.403 (good for a 114 wRC+) over 201 plate appearances while playing in the field at second base and all three outfield spots.  Haggerty looks to continue to play a key role on the Mariners’ bench this season, especially since fellow utilityman Dylan Moore might be a little more impacted during camp while recovering from core surgery.
  • Stephen Vogt weighed two other “serious baseball job offers” before becoming the Mariners‘ new bullpen and quality control coach in January.  As Vogt told NBC Sports Bay Area’s Brodie Brazil, “the Mariners were the best situation, the best offer, and being close to home — we did the best we could to make it not be a factor in our decision making.  The cherry on top is that I get to be with my family more in a season than I ever have.”  2022 was the last of Vogt’s 10 Major League seasons, and given that he has long been considered a future managerial candidate, it isn’t surprising that several teams were interested in being the first stop in Vogt’s post-playing career.
  • After a pretty quiet winter on the transactional front, the Rays are now viewing their slower offseason as an opportunity for their core players to enjoy some relatively rare stability, given how Tampa so often shuffles up its roster.  “Generally, we’re always trying to build that next year’s team to be as strong as we possibly can,” general manager Peter Bendix told Marc Topkin of the Tampa Bay Times.  “And this year, that led to us having this continuity and banking on some of this continuity, allowing our young players to grow and develop together and see if we can kind of gain from the experience that they’ve had up until this point.”  The Rays did part ways with several players in trades, free agency, or non-tenders, yet most of those holes were filled internally.  As Topkin notes, Zach Eflin (signed to a three-year, $40MM contract) and Rule 5 Draft selection Kevin Kelly are the only new players on Tampa Bay’s 40-man roster.  Of course, there is still plenty of time in the offseason for the Rays to make some more additions, plus one of the team’s many non-roster invitees could win a job in Spring Training.

Mariners Sign Carson Fulmer To Minor League Contract

The Mariners have signed Carson Fulmer to a minor league pact, according to the right-hander’s MLB.com profile page.  Fulmer has been assigned to Triple-A Tacoma.

After pitching 130 2/3 innings and appearing in every season from 2016-21, Fulmer didn’t see any big league action in 2022.  The Dodgers acquired Fulmer on a waiver claim last winter and briefly selected him to their active roster at the end of April, but Fulmer was designated for assignment a few days later without appearing in a game.  Los Angeles then outrighted Fulmer to Triple-A, where he spent the rest of the season before electing minor league free agency in October.

The year at Triple-A had mixed results, as while Fulmer had a 2.86 ERA over 56 2/3 innings for Oklahoma City, his 25.6% strikeout rate was only decent, and his 14.5% walk rate was well below average.  A .230 BABIP seems to have greatly aided Fulmer in limiting damage, which could partially be why the Dodgers didn’t give him another call-up despite that quality ERA.

The White Sox selected Fulmer with the eighth overall pick of the 2015 draft, and he made his MLB debut just a year later.  However, the righty didn’t live up to high expectations, posting a 6.56 ERA over 94 2/3 innings with Chicago before being designated for assignment in July 2020.  This move sparked a flurry of transactions for the out-of-options Fulmer, who went to the Tigers, Pirates, Orioles, again to the Pirates, then to the Reds on a series of waiver claims in a span of under eight months.  Cincinnati’s claim in March 2021 ended the carousel to some extent, as Fulmer spent the entire 2021 season in the Reds organization, though he struggled to a 6.66 ERA over 25 2/3 MLB innings.

Mariners, Leonys Martin Agree To Minor League Deal

The Mariners are in agreement with outfielder Leonys Martín on a minor league contract, tweets Ryan Divish of the Seattle Times. The Wasserman client will be in MLB camp as a non-roster invitee.

It’s the second Seattle stint for Martín, who spent parts of the 2016-17 seasons in the Pacific Northwest. The former campaign was one of the best of his career, as he stole 24 bases while hitting .247/.306/.378 across 143 games. Statcast’s Outs Above Average suggested he played Gold Glove caliber defense in center field, his calling card throughout his early run in the big leagues. Martín had previously spent three years as the primary center fielder for the Rangers, where his glove represented his best asset.

The lefty-hitting Martín never made much of an offensive impact, as low walk rates and a lack of power reduced his overall upside at the plate. He posted below-average hitting numbers throughout his career and carries a .244/.301/.367 line in just under 2800 trips to the dish. When he reached base, Martín rated as a plus baserunner. He twice topped 30 steals in a season and has taken 126 bags over parts of nine years.

Martín hasn’t played in the big leagues since struggling to a .199/.276/.343 showing in 65 games for the 2019 Indians. He went to Japan midway through that season, signing on with the Chiba Lotte Marines of Nippon Professional Baseball. The Cuban outfielder has spent the last three and a half years there, combining for a .220/.350/.461 line with 75 homers, an excellent 13.7% walk percentage but a lofty 25.3% strikeout rate over 1441 plate appearances.

After putting up an OPS north of .830 in each of his first three seasons with the Marines, Martín had a disappointing year in 2022. He’s coming off a .163/.293/.317 showing in 68 games. That marked a disappointing end to what had been a generally successful tenure in Japan.

Martín returns to the affiliated ranks in hopes of an MLB comeback. He’ll be 35 next month and presumably isn’t the excellent runner or defender he was at his peak. The M’s will give him a look as a depth outfielder to see if he’s still capable of playing solid defense up the middle. Julio Rodríguez obviously has the position locked down. Sam HaggertyJarred Kelenic and Taylor Trammell can each cover center but are better suited for corner outfield work. Well-regarded prospect Cade Marlowe joins them on the 40-man roster and has yet to make his major league debut. It’s hard to envision Martín cracking the roster out of camp but he’d bring 17 years of professional experience to Triple-A Tacoma if he starts the season in the minors.

Poll: Will The Mariners Trade Chris Flexen?

Early in the offseason, it looked as though there was a good chance the Mariners would move one of their two candidates for the fifth spot in the rotation. The quartet of Luis Castillo, Robbie Ray, Logan Gilbert and George Kirby create a standout set of options in slots one through four, and Seattle has a pair of solid back-of-the-rotation options in Marco Gonzales and Chris Flexen. Behind that duo, prospects like Emerson Hancock, Bryce Miller and Taylor Dollard have all reached Double-A and enjoyed success there, placing them within reasonable proximity of MLB readiness. Miller, in particular, cracked the back of some top-100 lists this year, landing 74th on Kiley McDaniel’s list at ESPN, 98th at MLB.com and 100th at Baseball America.

It’s a strong collection of depth, and the presence of Miller, Hancock and Dollard seemed like it could be enough to sway the Mariners to move one of Flexen or Gonzales. Flexen, as a free agent next offseason* with a palatable $8MM salary — compared to the $18.5MM still owed to Gonzales through 2024 — seemed to be the likeliest candidate. That’s true not only from an on-paper standpoint, but also when considering that president of baseball operations Jerry Dipoto plainly acknowledged in November that he’d been receiving trade interest in Flexen at the annual general managers’ meetings.

(*=There seems to be some continued confusion regarding this, as Flexen won’t have six years of Major League service time after the season, but MLBTR has confirmed that he will become a free agent next winter, as is the case with the vast majority of KBO/NPB signees whose free agent contracts expire.)

The Mariners, however, were never going to give Flexen away just to shed his salary, and the fact that he remains with the club is a clear indicator that another club has yet to put forth an offer Dipoto & Co. felt was commensurate with Flexen’s value. The extent of that value is subjective, but Flexen would be a clear upgrade to the back of several teams’ rotations.

Since returning from a successful one-year stint in the Korea Baseball Organization, he’s pitched to a 3.66 ERA in 317 2/3 innings. Granted, his 92.4 mph average fastball and 16.5% strikeout rate are below average, but Flexen also has sharp command (6.8% walk rate). He keeps lefties in check with the help of an above-average changeup and has generally done a good job keeping the ball in the yard since his MLB return. Flexen has benefited slightly from a pitcher-friendly home environment, but his numbers away from T-Mobile Park (3.75 ERA, 1.12 HR/9) are only slightly worse than those compiled when pitching at home in Seattle (3.57 ERA, 0.91 HR/9).

Because Flexen’s numbers were superior to those of Gonzales across the board, some argued that Gonzales should be the odd man out, despite his relatively lengthy tenure with the club. Gonzales is nearly three years older, however, has more than double the money remaining on his contract. Flexen’s trade value was and is higher, and while he alone wouldn’t have fetched a substantial upgrade to the Seattle lineup, he could certainly have been included in a package that worked toward that endgame.

Now, however, the majority of the teams around the game have exhausted the bulk of their offseason budget and filled the rotation vacancies that existed early in the winter. That ostensibly points toward both Flexen and Gonzales beginning the year with Seattle, perhaps with one in a long relief role. It’s always possible that a spring injury elsewhere on the staff would necessitate a scenario wherein both Flexen and Gonzales are part of the Opening Day rotation.

That said, the injury component still looms as a possibility for other clubs. Even teams that right now believe their rotations to be full could run into trouble over the next 50 days. Nary a spring training goes by without multiple pitchers going down to major injury; situations like the one that popped up today in Milwaukee — where Aaron Ashby is being slowed by shoulder fatigue — are commonplace this time of year. As the exhibition season wears on, more severe injuries that threaten long chunks (or the entirety) of an established pitcher’s season will arise. Many teams are in positions like the Mariners, where they have the depth to withstand such a hit. Others, however, are already looking at questionable depth beyond their top few names (e.g. White Sox, Blue Jays, Padres — to varying extents).

Injuries are an inevitability this time of year, and the Mariners’ depth will likely be attractive to other clubs as health troubles throughout the league arise. Seattle may prefer to stockpile that depth, but moving Flexen would likely free up some resources to expand the budget for in-season acquisitions. It’s also possible that they take on some salary to address another need on the big league roster by way of the Flexen trade itself.

For what it’s worth, Corey Brock of The Athletic speculated in his latest mailbag that the Mariners will ultimately find a deal for Flexen during spring training when an injury on another club creates a need, though it’s just as possible that said injury occurs on Seattle’s staff and takes Flexen out of the trade equation entirely.

Let’s put this one up to a vote for MLBTR readers to weigh in (link to poll)…

Will the Mariners trade Chris Flexen before Opening Day?

  • No, they'll keep the depth. 60% (2,566)
  • Yes, they'll find a trade partner in Spring Training. 40% (1,697)

Total votes: 4,263

Quick Hits: Muñoz, Sadler, Vavra

Mariners president of baseball operations Jerry Dipoto spoke with the media this week, including Shannon Drayer of 710 ESPN, in advance of the start of Spring Training. During those talks, Dipoto provided an update on reliever Andrés Muñoz.

Muñoz, 24, had a tremendous breakout last year, posting a 2.49 earned run average over 64 appearances. That ERA probably shortchanges Munoz a bit, who struck out 38.7% of batters faced while walking just 6% of them and got ground balls at a 52.6% clip. ERA estimators all thought he actually deserved better, including a 2.04 FIP, 1.84 xERA and 1.74 SIERA. After the club was eliminated from the postseason in October, he underwent foot surgery, but he’s already out of a walking boot and began a throwing program two weeks ago.

The fireballer has emerged as a key piece of the club’s bullpen, something they seemingly anticipated when they extended him after the 2021 season. The righty had just returned from Tommy John surgery and made a single appearance that year, but the M’s had enough faith to sign him to a four-year, $7.5MM extension with three club options. That could keep him as a fixture of the club’s relief corps through the 2028 season, and his current health is surely a good sign for the club going into 2023.

Other notes from around the league…

  • Dipoto also provided an update on another reliever in 32-year-old Casey Sadler, who is coming off a season lost to shoulder surgery but is going to be ready to go for Spring Training this year. In 2021, Sadler made 42 appearances for the M’s with a ridiculous 0.67 ERA. That level of run prevention was in no way sustainable, with Sadler benefitting from a .188 batting average on balls in play and 90.9% strand rate. But his 25.5% strikeout rate, 6.9% walk rate and 62.9% ground ball rate all point to an excellent campaign nonetheless, with Sadler pegged for a 2.48 FIP, 2.41 xERA and 3.06 SIERA. Unfortunately, he required the surgery on his shoulder in March of 2022, which kept him out for all of that year. The Mariners outrighted him off the roster in November but re-signed him to a minor league deal. “If we get that ’21 version of Casey Sadler with the bullpen group we currently have, that just takes us to a different level,” Dipoto said. Despite trading Erik Swanson to the Blue Jays in the Teoscar Hernández deal, the M’s bullpen is still pretty packed. Munoz should be joined by Paul Sewald, Diego Castillo, Matt Brash, Penn Murfee, Matt Festa and Trevor Gott, as well as Rule 5 draftee Chris Clarke. If the rotation is fully healthy, Chris Flexen should be in the bullpen as well as a long reliever. Sadler was so good in 2021 that he could force his way into the picture if he looks like he’s back on track. Despite the crowding, pitcher injuries are fairly inevitable and this pile of depth should serve Seattle well as the season progress.
  • Orioles utility player Terrin Vavra, 26 in May, cracked the majors last year and managed fairly well by hitting .258/.340/.337 in his first 103 plate appearances. That production was just barely below league average, with his wRC+ coming in at 97, though he hit a much sturdier .324/.435/.451 in Triple-A. Between the two levels, he played second base, third base, shortstop, and all three outfield positions, making him a usefully versatile piece of the club’s roster. It seems he’s not satisfied with that level of versatility and has been working to add first base to his repertoire this offseason. “I don’t think until I really play a game over there, I’ll truly feel the most comfortable, but that’s what spring training’s for,” Vavra tells Nathan Ruiz of The Baltimore Sun. “I think I’ll get some opportunities to showcase that and showcase other talents and try and make my case. I want to be able to show that I can do that, and I want the coaching staff to be confident if they had to send me out there, Day 1 of spring training even.” The O’s have been looking to find left-handed bats to complement right-hander Ryan Mountcastle in the first base mix, acquiring Lewin Díaz and Ryan O’Hearn this offseason, as well as signing Franchy Cordero, Josh Lester and Nomar Mazara to minor league deals. But Vavra, who also hits left-handed, could have a leg up on that group since none of them are on the 40-man but Vavra is. On the other hand, Vavra has option years remaining and could be ticketed for some more time in the minors if he gets squeezed off the active roster.

Mariners Outright J.B. Bukauskas

The Mariners announced that reliever J.B. Bukauskas has gone unclaimed on waivers. He’s been sent outright to Triple-A Tacoma and will be in big league camp as a non-roster Spring Training invitee.

Bukauskas didn’t have a particularly long stay on the Seattle 40-man roster. Claimed off waivers from the Diamondbacks on January 17, he lost his spot earlier this week when the M’s grabbed Tayler Saucedo from the Mets. Seattle quickly ran Bukauskas through waivers and will now be able to retain a former first-round draftee and highly-regarded prospect without allocating a 40-man spot.

The 26-year-old was the 15th overall pick in the 2017 draft by the Astros. Houston flipped the UNC product to Arizona two summers later as part of a four-player package for Zack Greinke. A starter early in his minor league days, Bukauskas has come with questions about his ability to hold up in a rotation because of inconsistent command dating back to college. Those concerns have borne out over the past two seasons, as the Snakes moved him to relief after adding him to the roster over the 2020-21 offseason.

Bukauskas made his MLB debut in April ’21, eventually getting into 21 contests. He was hit hard for 19 runs through his first 17 1/3 big league innings despite averaging 94.5 MPH on his fastball and generating plenty of whiffs on his mid-80s slider. An elbow strain cost him a chunk of that season, and a lat injury suffered in Spring Training sidelined him for the first half of last year.

While he didn’t return to the mound until July, Bukauskas closed out the 2022 season with a nice run at Triple-A Reno. Pitching in an extraordinarily hitter-friendly park, he posted a 2.66 ERA with a solid 23.8% strikeout percentage and an excellent 5% walk rate. Nevertheless, he never got another MLB opportunity in a below-average Arizona bullpen and has found himself squeezed off two clubs’ rosters in a matter of weeks.

Bukauskas will try to pitch his way back onto the radar in spring camp and, if necessary, with Tacoma to open next season. The M’s already have a strong bullpen, with Andrés MuñozPaul SewaldDiego CastilloMatt Brash, Trevor Gott and likely Penn Murfee penciled into jobs. Matt Festa is out of minor league option years and has a strong case to hold onto a roster spot, while whomever of Marco Gonzales and Chris Flexen doesn’t win the #5 starter role could be in the bullpen. The M’s would also have to carry Rule 5 draftee Chris Clarke on the active roster or waive him and, if he clears, send him back to the Cubs. Bukauskas joins Taylor WilliamsCasey SadlerRiley O’Brien and Kyle Tyler among the non-roster depth options in the organization.

Mariners Notes: Left Field, Brash, Rotation

The Mariners’ plans in left field have looked fairly straightforward since the team signed AJ Pollock to a one-year deal last month, but president of baseball operations Jerry Dipoto nonetheless confirmed to reporters last night that the expectation is for left field to a platoon between Pollock and one of Jarred Kelenic or Taylor Trammell (Twitter link via Ryan Divish of the Seattle Times).

Both Kelenic, 23, and Trammell, 25, are recent top-100 prospects who at one point were candidates to hold down long-term spots in the Seattle outfield. Kelenic, in particular, was touted as a potential star but has struggled in the big leagues to this point despite a .302/.372/.574 output in 537 plate appearances at the Triple-A level. His struggles against fellow lefties have been particularly pronounced, but Kelenic did turn in a .249/.330/.503 slash against right-handed pitching in 2022 (Triple-A and MLB combined). Trammell, meanwhile, hit .274/.365/.527 against righties between Triple-A and MLB. There’s some understandable hope, then, that a platoon arrangement with one of Kelenic/Trammell and Pollock (.286/.316/.619 against lefties in 2022) could form a productive tandem.

Trammell was heralded as the superior defender of the pair during his prospect days, though neither he nor Kelenic has posted standout defensive grades thus far in the big leagues. Kelenic has more experience in the corners and has drawn above-average marks for his work there. He’s also been more apt to barrel the ball and has been less strikeout-prone, though his 29.9% mark in the big leagues is obviously problematic.

Both Kelenic and Trammell were featured in a piece by Baseball America’s Kyle Glaser, wherein he polled scouts for opinions on some recent top prospects who’ve graduated to the Majors but struggled to establish themselves. Kelenic drew more praise between the two, particularly for substantial defensive improvements, but scouts who spoke to Glaser offered fairly bearish views of both players’ swings at this point. However, Mariners GM Justin Hollander said yesterday that hitting coach Jarret DeHart has been working with Kelenic and gone through a motion-capture breakdown of his swing this offseason, and the results have been “over-the-top awesome” (link via Corey Brock of The Athletic).

Both Kelenic and Trammell are still young, and it’s fairly common to see a swing change or mechanical adjustment bring about major turnarounds in a player’s outlook. The Mariners clearly aren’t giving up on either player yet, though with both entering their final minor league option year, this is a crucial season for Kelenic and Trammell. Should they falter, the M’s have another lefty-swinging outfield bat who’s nearly ready for a Major League look; 25-year-old Cade Marlowe is on the 40-man roster and turned in a combined .287/.377/.487 slash between 120 Double-A games and 13 Triple-A games in 2022.

Kelenic and Trammell aren’t the only once-vaunted Mariners prospects who’ve turned in shaky big league results to this point. Righty Matt Brash won the fifth starter’s job out of spring training in 2022 but was tagged for 17 runs while posting a 19-to-17 K/BB ratio through his first 20 innings (five starts). That prompted the team to option Brash back to Triple-A Tacoma, and when he returned in July, he was used exclusively as a reliever.

That’ll be Brash’s role in 2023 as well, Dipoto confirmed (Twitter link via Divish). It’s easy to see why the Mariners are intrigued by the switch. Brash has been a starter for most of his career, but he returned to the Majors and obliterated opposing lineups while working in short relief last summer; from July 9 through season’s end, the 24-year-old pitched to a 2.35 ERA with a huge 33.9% strikeout rate. His 12.6% walk rate still needs refinement, but Brash’s heater jumped from an average of 96.3 mph in the rotation to 97.8 mph out of the ‘pen and his 14% swinging-strike rate was excellent.

It’s always possible that there will be rotation innings for Brash down the road, but the Mariners look to have several spots locked up long-term. Ace Luis Castillo signed a five-year, $108MM extension after being acquired in a trade last summer, and left-hander Robbie Ray inked a five-year, $115MM in free agency last offseason. Young arms Logan Gilbert and George Kirby, meanwhile, are controllable for another five and six seasons, respectively.

Both Gilbert and Kirby have made good on their status as former first-rounders and top prospects, quickly cementing themselves as high-quality big league hurlers. And, as Dipoto tells it, the duo won’t be facing any hard innings limitations in 2023 (via Brock). Gilbert threw 185 2/3 innings over the life of 32 regular-season starts in 2022, while Kirby notched a combined 156 2/3 innings between Double-A, Triple-A and the big leagues. Both pitchers turned in an ERA in the low-3.00s with sharp strikeout and walk rates (Kirby, in particular). The pair might be eased into spring work, but the goal seems to be for each to make a five-inning start in the late stages of camp, setting the stage for them to work without limits once the season begins.

The group of Castillo, Ray, Gilbert and Kirby is among the best rotation quartets in baseball, but the fifth spot in the rotation remains a source of at least some uncertainty. Seattle has a pair of candidates in Marco Gonzales, a mainstay over the past five years, and KBO returnee Chris Flexen, who’s posted a 3.66 ERA in two seasons since signing in Seattle. Both pitchers have been floated as possible trade candidates throughout the winter. Gonzales is owed a combined $18.5MM from 2023-24, while Flexen will earn $8MM in 2023 before becoming a free agent in the offseason.

There’s been little indication of serious trade talks involving either in recent weeks, but it’s certainly possible that another club will show increased interest once early-spring injuries inevitably begin to arise. Then again, having both on hand gives the Mariners themselves an important safety net in the event of an in-house injury, so there’s little pressure to force a deal if the return isn’t meaningful.
