Previewing the MLB 2024-25 first base free-agent class

With the regular season winding down, a number of teams (and their fanbases) are already starting to turn their attention towards the offseason. Identifying free agent targets is a big part of that prep work, so it’s worth taking an early look at the players who’ll be available on the open market.

MLBTR’s Steve Adams kicked things off with a look at a generally weak catching class. There’s a stronger group at first base, even if age is an issue for a lot of these players. 

A quick note on eligibility: we’re looking only at players who have appeared in the majors this season and are either primary first baseman or have logged 100+ innings at the position. Utility players like Enrique Hernández and Brandon Drury can play first base but will be covered in future positional previews. Ages are for the 2025 season. Stats are through play on Sept. 18.

Top of the class

• Pete Alonso (30)

Alonso is in a tier of his own in this year’s first base class. He is one of the sport’s preeminent power bats. Even in a relative down year, he has drilled 33 homers while slugging .472. Alonso has topped 30 longballs in all five full seasons of his career and was on a 43-homer pace during the shortened schedule. 

His .246/.331/.472 batting line is 26 points better than league average, according to wRC+. That’s tied for fifth among first basemen (min. 400 PAs) and feels like Alonso’s floor for the next few years.

The Mets will make him a qualifying offer, which he’ll reject. Alonso reportedly declined a $158M extension offer in 2023 — made under former GM Billy Eppler. 

He’ll probably take aim at $200M, though it has been more than a decade since any first basemen hit that mark. The more recent Matt Olson ($168M) and Freddie Freeman ($162M) guarantees may be more realistic benchmarks.

Everyday players

• Christian Walker (34)

Walker didn’t get a real MLB look until his age-28 season. He seized the opportunity once it finally presented itself and is one of the best all-around first basemen in the sport. Walker won consecutive Gold Gloves between 2022-23 while posting an OPS above .800 in three straight years. 

He has 26 homers — including seven in just 29 plate appearances as a visitor at Dodger Stadium — with an excellent .257/.342/.485 slash line. An oblique strain that shelved him through August is the main reason he might not get to 30 homers for a third straight year.

Arizona has an easy call to tag Walker with a qualifying offer. He’s likely to decline in search of a three- or four-year contract. Multi-year deals for first basemen in their mid-30s are rare, but Walker should be in high enough demand to merit it.

• Paul Goldschmidt (37)

Goldschmidt had one of the worst stretches of his career early in the season. As Steve Adams explored this week, the 2022 NL MVP has kicked things into gear in recent weeks. This will be Goldy’s worst season overall, as he has career lows in all three slash stats (.242/.302/.412). 

His .270/.322/.485 line since the All-Star break is more in line with what the Cardinals were expecting. Goldschmidt has never hit free agency — he signed extensions with both Arizona and St. Louis — and therefore has never received a qualifying offer. 

It seems unlikely that St. Louis would risk him accepting a salary exceeding $21M for next year, but that’d be an alright investment if the Cards expect him to carry his second-half form into 2025.

• Carlos Santana (39)

The Twins signed Santana for $5.25M in February. He had a terrible April but has been a steady, productive player over the past few months. Since the start of May, the switch-hitter owns a strong .253/.339/.446 line with 18 homers across 446 plate appearances. He remains one of the three to five best defensive first basemen in the game despite his age. 

The ultra-durable Santana has again avoided the injured list and has reached 140 games for the 12th time in his career. He certainly doesn’t carry the upside of Alonso or Walker, but he has easily outperformed Minnesota’s modest investment.

• Justin Turner (40)

Turner is more of a designated hitter than a full-time first baseman, but he has gotten 35 starts at the position between the Blue Jays and Mariners. Turner had a fairly modest .256/.350/.372 showing over 91 games with Toronto. It looked as if he might be slowing down at age 39, but he has found another gear since being traded at the deadline. Turner owns a .260/.361/.420 slash with five home runs in 39 games with Seattle — impressive power output in a home park that has stymied a lot of the M’s offensive acquisitions. 

By measure of wRC+, Turner has been 17 percentage points above league average at the plate. That’s slightly better than last year’s .276/.345/.455 showing with the Red Sox. Turner got $13M last offseason and still hasn’t dropped off.

Platoon and part-time bats

• Josh Bell (32)

Bell had a rough first few months, hitting .239/.305/.394 in 104 games with the Marlins. He has found his stride after a deadline trade to Arizona, where he carries a .278/.364/.421 slash with four homers through 154 trips to the plate. The aggregate production is still middling — a league average .249/.320/.401 line with very poor defensive grades — but Bell is finishing the season on a high note. He has been a streaky hitter throughout his career who can hit in the middle third of a lineup when he’s at his best.

• Mark Canha (36)

Canha has logged a career-high 356 1/3 innings at first base, a bit more time than he has played in the outfield. That’s probably a sign of things to come as he gets into his late-30s. The affable veteran has a .238/.341/.342 slash over 451 plate appearances between the Tigers and Giants on the season. He won’t match this year’s $11.5MM salary but should have no trouble finding another big league deal.

• Donovan Solano (37)

Late-career Solano just hits. The righty-swinging infielder has been an average or better hitter in six straight seasons. Solano has carried that over in stints between the Giants, Reds, Twins and Padres. He’s sporting a .286/.340/.412 slash with seven homers through 285 plate appearances for San Diego this season. The market doesn’t value Solano’s skillset highly — he had to settle for a minor league deal last offseason — but he’s a nice player to have in a bat-first role off the bench.

• Rowdy Tellez (30)

Tellez started the season horribly, went on an absolute tear midway through the summer, and has crashed back to earth in September. In aggregate, he has a .245/.302/.395 slash with 13 homers over 410 plate appearances for the Pirates. It’s slightly below-average offense and sub-replacement production overall considering his lack of defensive value. Tellez has decent career numbers against right-handed pitching (.235/.302/.450) and is a better fit as a lefty bench bat than a regular at first base.

Depth types

• José Abreu (38)

Abreu was one of the worst players in the league in the season’s first half. The former MVP hit .124/.167/.195 over 35 games. The Astros released him midway through the second season of his ill-fated $58.5M free agent deal. 

Reporter Francys Romero tweeted in June that Abreu would sit out the rest of the season but could make a comeback effort next year. It’d be on a minor league deal, but if he gets back to the majors, he’d only make the league minimum with his new team. Houston still owes him the rest of his $19.5M salary.

• Garrett Cooper (34)

Cooper appeared in 36 games between the Cubs and Red Sox, hitting .206/.267/.299 while striking out 30% of the time. He has been far better over a 19-game stint in Triple-A with the Orioles, where he sports a .299/.388/.493 slash with four homers.

• J.D. Davis (32)

Davis is in Triple-A with the Orioles, his fourth organization of the year. After being cut loose by the Giants in a late spring cost-saving move, he has slumped to a career-worst .218/.293/.338 line between the A’s and Yankees. 

Davis hasn’t hit at all in the minors either, striking out at a 44.4% clip while batting .150 in 30 games. He was a solid regular for San Francisco just last season and should be able to find a minor league deal somewhere.

• Joey Gallo (31)

Gallo is hitting .152/.276/.305 across 67 games with the Nationals on a $5M free agent deal. Washington is going to decline its end of a 2025 mutual option. Gallo is striking out as much as ever and hasn’t hit for anywhere near the level of power necessary to offset that.

• Yuli Gurriel (41)

Gurriel spent most of the season in Triple-A with the Braves. He had an impressive .292/.378/.485 showing. While that didn’t earn him a look in Atlanta, the Royals acquired him in a minor trade after losing Vinnie Pasquantino to injury. Gurriel is hitting .385 over 10 games with Kansas City.

• Dom Smith (30)

Smith got a decent run as the Red Sox’s fill-in while Triston Casas was injured. The former Met took 278 plate appearances and posted a slightly below-average .237/.317/.390 line with six home runs. He briefly caught on with the Reds after Boston let him go. 

Smith didn’t hit over a minuscule nine-game sample in Cincinnati and has been a free agent since the Reds removed him from the 40-man roster earlier this month.

• Gio Urshela (33)

Urshela is primarily a third baseman, but he logged 15 starts at first base for Detroit this year. Between the Tigers and Braves, he owns a mediocre .241/.280/.335 slash with six homers across 422 plate appearances. It’s his least productive year since he broke out as an everyday player with the Yankees in 2019.

• Jared Walsh (31)

The former All-Star hasn’t been the same since a bout with thoracic outlet syndrome. Walsh hit .226/.317/.321 in 17 games for the Rangers while Nathaniel Lowe was on the injured list early this season. He subsequently hit .185 with a 37% strikeout rate in Triple-A for the White Sox and was released a couple weeks before the deadline.

Player options

• Cody Bellinger (29)

Bellinger can opt out of his three-year, $80M deal with the Cubs. He’d be leaving $50M on the table to do so and has another opt-out chance after next season. 

Bellinger has had a nice season but hasn’t answered teams’ questions about his subpar exit velocities. He’s hitting .268/.330/.435 with 18 homers while striking out at just a 16% clip. He’s still capable of playing center field but has also gotten decent run in right field and at first base. 

Bellinger could probably beat $50M if he simply wanted to maximize his guarantee, but he’s not likely to match next year’s $27.5M salary on a multi-year pact. He could bet on himself and view the 2025-26 offseason as the right time to opt out.

• Rhys Hoskins (32)

Hoskins signed with the Brewers on a two-year, $34M deal that allowed him to opt out after the first season. It’s a net $18M call. He’d collect a $4M buyout if he opts out or could secure an $18M salary for next season (plus a matching $4M buyout on a 2026 mutual option). 

This isn’t a great time to retest the market. FanGraphs and Baseball Reference have each graded the typically consistent Hoskins as a replacement level player this year. He has 25 homers but personal lows in batting average (.212) and on-base percentage (.299) while striking out a career-high 28% rate. 

If he goes on a tear in the playoffs, maybe the calculus changes, but this looks like an option that’ll be exercised.

• Wilmer Flores (33)

Flores holds a $3.5M option on his deal with the Giants. San Francisco would have an $8.5M option if the veteran infielder declined his end. 

That won’t be necessary, as Flores looks like a lock to take the $3.5M salary. He hit .206/.277/.318 across 242 plate appearances and suffered a season-ending right knee injury in July.

Club options

• Ryan O’Hearn (31)

The Orioles hold an $8M option for next season. O’Hearn’s strong first half made that look like a clear bargain. The left-handed hitter went into the All-Star break with a .274/.335/.456 line with nearly as many walks as strikeouts. His plate discipline is still strong but his power has dissipated in the second half. 

O’Hearn only has two homers with a .224/.317/.340 line since the Break, including a .163/.226/.245 showing this month. Baltimore should have a lot of payroll flexibility and could bet on O’Hearn to bounce back, but this is more of a borderline call than it seemed six weeks ago.

• Anthony Rizzo (35)

The Yankees are going to opt for a $6M buyout in lieu of a $17M option on Rizzo. The three-time All-Star is hitting .219/.285/.330 over 347 plate appearances. He missed a couple months earlier in the season after breaking his arm in a collision with Boston reliever Brennan Bernardino. This has been Rizzo’s toughest year since his rookie campaign.
