Just before the holidays, the hot stove roared to life for the first base and DH market as a host of players all came off the board over the course of a matter of days. Josh Naylor and Nathaniel Lowe changed hands via trade, while Christian Walker, Paul Goldschmidt, Carlos Santana, Joc Pederson, Andrew McCutchen, and Josh Bell all inked deals in free agency. The boom in this corner of the market even impacted depth pieces such as Darick Hall and Matt Mervis, both of whom found new homes in minor league free agency and via trade respectively. Even after that run of deals coming together, however, plenty of interesting first base and DH options remain available. Pete Alonso is of course the top free agent first baseman available this winter, while Anthony Rizzo and Mark Canha are among the more interesting bounce-back candidates who could still be had on the open market.
Among the most notable options available at this point in the winter for those looking to fill a hole at DH are a pair of aging right-handed bats, both of whom are World Series champions with decorated resumes: Justin Turner and J.D. Martinez. Both players appear to be in the twilight of their careers but managed to put up above-average offensive results last year and are looking to extend their careers in free agency this winter. Those similarities come with noticeable differences in their overall profiles that give each certain advantages over the other, creating an interesting contrast between the pair.
Turner, who celebrated his 40th birthday back in November, is a free agent for the third consecutive offseason. The longtime Dodgers stalwart was among the game’s premier pure hitters during his time in Los Angeles, and in nine seasons with the club he slashed an excellent .296/.375/.490 (136 wRC+). No one should expect that level of production from Turner at this stage of his career, but even though his days of All-Star appearances and top-10 finishes in MVP voting appear to be behind him he’s remained a consistent and solidly above-average hitter in two seasons since departing his longtime club. He’s split time between the Red Sox, Blue Jays, and Mariners since leaving the Dodgers, and in that time has slashed .268/.349/.422 with a wRC+ of 116 while accruing 2.2 fWAR.
Digging a little deeper, Turner gets to his production in largely the same way he always has, with a high-contact approach and strong plate discipline. He’s struck out at an identical 17.6% clip in each of the last two seasons, just a hair behind Juan Soto’s 17.5% strikeout rate. In 2024, he paired that with an excellent 10.9% walk rate that placed him alongside Carlos Santana and Yordan Alvarez in a tie for the 27th-highest walk rate among qualified hitters this year. That’s not to say Turner is flawless as a hitter, of course; the veteran has never been much of a power threat, and 2024 saw him hit just 11 homers as his ISO dropped to .124. That was the 16th-lowest figure among qualified hitters last year and is Turner’s worst finish in the category since he arrived in L.A. back in 2014. His 4.6% barrel rate and 32.5% Hard-Hit rate were similarly bottom-16 figures in the majors this year.
As for Martinez, the six-time All-Star spent his peak years in Detroit and Boston with a brief sojourn to Arizona in the middle. From 2014 to 2019, only Mike Trout and Aaron Judge topped Martinez’s 151 wRC+ as he slashed an incredible .307/.373/.581 with 207 homers in 816 games. Of course, those peak years are now long behind him. Since the start of the 2021 season, Martinez has slashed .268/.334/.486 (122 wRC+) with noticeable peaks and valleys in his production based primarily on his power output. The slugger mashed more homers (33) in 2023 than he did in the 2022 and ’24 seasons combined (32), and depending on his power output can oscillate from a roughly replacement-level bat to a slugger still worthy of an All-Star appearance.
With that being said, Martinez’s plate discipline pales in comparison to that of Turner. Over the past two seasons, Martinez has struck out at a hefty 29.8% clip while walking a solid but unspectacular 8.5% of the time. It’s also worth noting that, while he’s three years younger than Turner is, he provides even less defensive value than his 40-year-old contemporary. Turner played in 139 games and started in the field for just 44 of them in 2024 (almost exclusively at first base), but you’d have to go all the way back to 2018 to find a year where Martinez started that many games in a season.
It should also be noted that Martinez’s platform season is far worse than that of Turner’s, as he hit just .235/.320/.406 (108 wRC+) in 120 games with the Mets and started losing playing time to deadline pickup Jesse Winker late in the year. While he posted a strong .417 on-base percentage in a limited role during the club’s postseason run, he hit for surprisingly little power with no extra-base hits. Turner, meanwhile finished strong down the stretch with the Mariners as he hit .264/.363/.403 (126 wRC+) in 48 games after being traded to Seattle over the summer.
On the other hand, Martinez’s underlying numbers suggest a resurgence could be in the cards for 2025. His 14.7% barrel rate last year was just a hair behind those of Austin Riley and Teoscar Hernández, while 45.5% Hard-Hit Rate places him squarely between Elly De La Cruz and Joc Pederson. That contributes to a .356 xwOBA that was nearly 40 points higher than his wOBA last year. Meanwhile, Turner’s profile is more or less maxed out, with his .327 wOBA in 2024 nearly matching his .330 xwOBA and his 2023 production actually outstripping his expected numbers noticeably.
So, if your team needed a DH, which veteran would you rather bring in for 2025? Would you value Turner’s consistency, discipline, and limited ability to play the field? Or are you more drawn to Martinez’s power, upside, and relative youth?
