While the current free agent market for position players has generally been seen as one of the weaker ones in recent memory, there is one area where this winter’s crop has notable depth: right-handed sluggers. That market, at which Teoscar Hernandez resides as the clear top option this winter, is typically deepest at the lower levels of free agency. This season’s crop certainly has some depth at that level as well, with the likes of Adam Duvall and Tommy Pham currently available. The middle of the free agent market is where this group stands out, however. Mitch Garver has already landed with the Mariners on a two-year deal, with first baseman Rhys Hoskins and veteran infielder Justin Turner among the other options still available.
Two of the best regarded players in this part of the market are sluggers Jorge Soler and J.D. Martinez. Both are primarily used as designated hitters and are coming off strong platform campaigns that saw them rebound from down performances in the previous three campaigns. Both have flashed 40-homer power in their careers previously, and both project for a similar guarantee this offseason: in our annual Top 50 MLB free agents list, MLBTR projected Soler for three years and $45MM guaranteed while Martinez projected for two years and $40MM.
Martinez sports the stronger platform campaign, having slugged 33 home runs in just 479 trips to the plate while slashing .271/.321/.572 with a wRC+ of 135. The veteran slugger also has the more prestigious track record as a six-time All Star who finished fourth in AL MVP voting back in 2018. Since Martinez broke out as a member of the Tigers back in 2014, he’s slashed an impressive .293/.359/.550 while never posting a below-average wRC+ in a full season. During that time, only Manny Machado, Mike Trout, and Nolan Arenado have slugged more homers than Martinez among active players, and his 140 wRC+ during that time ranks 12th among all active players. By contrast, Soler’s career-high wRC+ falls short of that impressive 140 mark and Soler has often interspersed seasons closer to league average between his All Star-caliber peaks.
That being said, Soler has some notable advantages of his own. Most obviously, he’s entering his age-32 campaign, while Martinez turned 36 back in August. That four year age gap also leaves Soler as less of a risk to suffer age-related decline over the course of his next contract. Teams could be particularly concerned about Martinez’s durability after he missed over a month with back and groin issues in 2023, causing him to appear in just 113 games for the Dodgers last season. On the other hand, of course, Soler missed the entire second half of the 2022 season due to a pelvis injury, though he was largely healthy this past season.
Aside from his relative youth and better health in 2023, Soler is among the most reliable players in the game when it comes to drawing walks, as demonstrated by his 11% walk rate since the start of the 2016 season. In fact, Soler is one of just 13 players to post a walk rate over 10% in each of the past eight seasons. That’s a list that does not include Martinez, who last posted a walk rate at that level back in 2019. That steady demonstration of plate discipline also highlights the fact that Soler’s strikeout rate has steadily improved in recent years, even as Martinez’s has begun to balloon.
While Soler’s career strikeout rate of 26.7% is two points higher than Martinez’s own career mark of 24.7%, they’ve been trending in opposite directions. Soler struck out at a career 27.9% clip through the end of the shortened 2020 season, while Martinez sported a strikeout rate of 24.2%. Over the past three seasons, however, Martinez has actually struck out more often than Soler with a 26% strikeout rate against Soler’s 25.1% figure.
Much of that has to do with the 2023 campaign, where Martinez struck out in a career-high 31.1% of plate appearances while Soler’s own 24.3% rate was the second-lowest of his career. While that shift toward whiffs has allowed Martinez to access more of his previous prodigious power after a down season in 2022 that saw him slug just 16 home runs, it’s fair to wonder if some clubs may prefer Soler’s more balanced approach to Martinez’s pure power profile, even as the veteran slugger outperformed Soler by nine points of wRC+ in 2023.
While that may not be enough to make Soler a more attractive target than Martinez, one elephant in the room that has not yet been addressed is defense. Soler’s glove leaves much to be desired, as demonstrated by his -5 Outs Above Average in right field this year and his -29 figure in the outfield since the start of the 2016 season. While Soler’s defense doesn’t offer much value to teams, it can’t be ignored that he is at least capable of playing a corner outfield spot on a semi-regular basis, something that cannot be said for Martinez.
The veteran slugger last appeared regularly on the grass back in 2017, when he was a member of the Diamondbacks before NL teams had access to the DH. By contrast, Soler has made 182 starts in the outfield corners over the past three seasons, more than half of the games he’s appeared in during that time. Even as Soler is far from a quality defender in the outfield, Martinez lacks the ability to play the outfield on more than an emergency basis at this stage of his career, complicating his fit for teams that already have a player on the roster who receives semi-frequent starts at DH or even simply prefer to use the DH as a way to rest regulars throughout the season.
Given the pair’s many similarities, it’s hardly a surprise that the two sluggers have somewhat overlapping markets this winter. Both have been directly to connected to the Mariners and Diamondbacks this offseason, while the Mets, Angels, and Blue Jays are all also known to have at least some interest in adding a bat-first slugger to their lineups this offseason. Martinez has generally been connected to those latter teams more frequently than Soler, though both players figure to be fits for each of the aforementioned teams this offseason to say nothing of clubs like the Marlins and Brewers who have not yet been connected to this area of the market but would surely benefit from another bat-first player in the lineup.
So, which one do you think teams should prioritize? Is Martinez’s lengthy track record and unparalleled power potential too enticing to pass up, or does Soler’s youth, ability to play defense, and more balanced approach in recent years outweigh those considerations?
