Top extension candidates heading into the 2025 season

February 14th, 2025

Alex Bregman and Nick Pivetta became the latest free agents to find new teams, agreeing to deals Wednesday with the Red Sox and Padres, respectively.

A number of free agents remain available, but now that MLB.com’s entire Top 25 free agent list has been taken off the board, it’s time to look at players who could be candidates to sign contract extensions with their current clubs.

Keep in mind, extensions can happen for a number of reasons. Some clubs look to lock up young talent years in advance of free agency, while others could try to sign their players headed for free agency next offseason.

Here’s a look at 15 players who could be candidates for the next notable extension.

(Players are listed alphabetically with 2025 season age as of July 1.)

Luis Arraez, INF, Padres, age 28
Eligible for free agency after the 2025 season

Arraez will earn $14 million in his final year before free agency, and while the three-time batting champion has played for three teams since the start of 2022, he’s put himself in position to cash in with a nice multi-year deal thanks to a .323 lifetime batting average and two straight 200-hit seasons. San Diego appears interested in keeping Arraez in a Padres uniform, so perhaps the club will try to extend him before he becomes a free agent next fall. Despite a number of sizable financial commitments already in place beyond 2025, the Padres will have roughly $35 million coming off the books with Arraez, Michael King and Dylan Cease headed for free agency.

Hunter Brown, RHP, Astros, age 26
Eligible for free agency after the 2028 season

Brown won’t even begin his arbitration years until next offseason, but the Astros have been known to sign pre-arb players to extensions in the past. General manager Dana Brown was also part of a Braves front office that had great success locking up young players well in advance of free agency, so he’s no stranger to the process. Brown had an uneven year in his first full season as a big league starter (5.09 ERA in 155 2/3 innings in 2023), but he performed much better in 2024, posting a 3.49 ERA over 170 innings.

Lawrence Butler, OF, Athletics, age 24
Eligible for free agency after the 2029 season

Butler won’t be eligible for arbitration until the end of the 2026 season, but after his breakout 2024 campaign, he might be the type of player the Athletics would want to build around as they enter the Las Vegas era in 2028. Butler hit 22 home runs with 18 stolen bases and an .807 OPS in 125 games last season, though his second half -- 13 homers, 12 steals and an .898 OPS in 61 games -- showed the type of offensive force he can be. The Athletics opened the checkbook this winter to sign Luis Severino (three years, $67 million) and José Leclerc (one year, $10 million) while also trading for Jeffrey Springs, who is guaranteed $21.75 million over the next two years. Perhaps locking in an emerging young star could be in the cards for the Athletics, with Butler being an obvious candidate.

Garrett Crochet, LHP, Red Sox, age 26
Eligible for free agency after the 2026 season

The Red Sox dealt four prospects -- including a pair on MLB Pipeline’s Top 100 list -- to the White Sox for the talented left-hander, who agreed to a $3.8 million contract to avoid arbitration. Crochet is arbitration-eligible for the final time next season, after which he is slated to become a free agent. After giving up a huge haul to acquire the 25-year-old, it would make sense for Boston to try locking up Crochet on a long-term deal. The tricky part? Crochet will surely be seeking a deal commensurate with other top starting pitchers, though with only one season as a starter on his résumé, the Red Sox may want to see him repeat his breakout 2024 performance before spending big to extend him.

Oneil Cruz, SS/CF, Pirates, age 26
Eligible for free agency after the 2028 season

Over the past three years, the Pirates have locked up Ke’Bryan Hayes, Bryan Reynolds and Mitch Keller, showing a willingness to keep their young players in Pittsburgh. While extending Paul Skenes would be a dream, that’s unlikely to happen -- but what about Cruz? The shortstop-turned-center fielder had a bounce-back season in 2024, posting a 20-homer, 20-stolen base campaign after playing only nine games in 2023 thanks to a leg fracture. Pittsburgh doesn’t have any top outfield prospects, so extending Cruz would make sense.

Brenton Doyle, CF, Rockies, age 27
Eligible for free agency after the 2029 season

Doyle has won Gold Gloves in each of his first two seasons, showing the type of value he provides in the field. The Rockies have been aggressive when it comes to locking up their young players, signing Ezequiel Tovar to a pre-arb extension last year while also recently extending Ryan McMahon, Kyle Freeland and Antonio Senzatela during their arbitration years; could Doyle be next? Doyle -- who hit 23 home runs with 72 RBIs and 30 stolen bases in 149 games last season -- will likely be a Super Two next offseason, giving him four years of arbitration eligibility, but he won’t be a free agent until the end of 2029, when he’ll be entering his age-32 campaign.

Logan Gilbert, RHP, Mariners, age 28
Eligible for free agency after the 2027 season

The Mariners have a number of young starting pitchers who could be extension candidates, but Gilbert is the most experienced of the group and therefore the closest to free agency. The 27-year-old made his first All-Star team last season and led the league in innings pitched (208 2/3) and WHIP (0.887), earning down-ballot Cy Young votes despite a 9-12 record. Gilbert settled on a $7.625 million deal to avoid arbitration this season, but with two years of arbitration eligibility remaining, his salary should rise considerably in 2026 and ’27 if he continues to perform the way he has during his first three full seasons. It’s unlikely that Gilbert and the Mariners will work out an extension this season, but he could be a priority next offseason if he continues his current trajectory.

Riley Greene, OF, Tigers, age 24
Eligible for free agency after the 2028 season

The fifth overall pick in the 2019 Draft, Greene had his breakout season at age 23, hitting 24 home runs with 74 RBIs, an .827 OPS and 5.4 bWAR while making his first All-Star team last season. Greene won’t be eligible for arbitration until next offseason, and Detroit has shown a willingness to sign pre-arb extensions like the one Colt Keith landed prior to making his big league debut. The Tigers would love to extend Tarik Skubal, but the defending AL Cy Young winner is only two years from free agency and may choose to play those out to test the market. Greene is still under control for four years, so buying out his arbitration years and potentially a free-agent year or two might be an option for Detroit.

Vladimir Guerrero Jr., 1B, Blue Jays, age 26
Eligible for free agency after the 2025 season

The Blue Jays have already tried to extend Guerrero with a reported offer of more than $300 million, though the gap between the two sides appears to be fairly wide. Guerrero has said he won’t negotiate once Spring Training begins, leaving only a handful of days left before that self-imposed deadline arrives. Guerrero is said to be seeking a deal worth more than $400 million, which would be more than twice as much as the top first-base deals in recent years. Juan Soto’s $765 million contract with the Mets blew the roof off the market for top young hitters, with Guerrero at the top of the list of beneficiaries.

Jackson Merrill, OF, Padres, age 22
Eligible for free agency after the 2029 season

Merrill won’t be arbitration-eligible until the end of the 2026 season, but the Padres reportedly discussed an extension with him prior to last season, so it wouldn’t be a shock for the two sides to re-engage on the subject again. San Diego has done these type of deals before, with Fernando Tatis Jr. being the obvious example. Merrill’s debut season was spectacular, and if he follows up with another strong year, his price tag will only go up. The Padres could look to buy out his arb years in addition to some free-agent years, though it’s going to cost them.

Cal Raleigh, C, Mariners, age 28
Eligible for free agency after the 2027 season

Julio Rodríguez might be the face of the franchise in Seattle, but Raleigh has become the clubhouse leader and a local fan favorite. The defensive stalwart -- he won the AL Platinum Glove last season -- won’t be a free agent until his age-31 season, so perhaps locking in a long-term deal with the Mariners would be beneficial to both sides. Raleigh’s recent agent change (he left Scott Boras and hired Excel) sparked speculation that he would be open to an extension, and given his work behind the plate with Seattle’s young staff, it would make sense for the Mariners to keep him in town for the foreseeable future.

J.T. Realmuto, C, Phillies, age 34
Eligible for free agency after the 2025 season

Kyle Schwarber, DH, Phillies, age 32
Eligible for free agency after the 2025 season

Schwarber is entering the final season of his four-year, $79 million contract, having become one of the leaders of Philadelphia’s clubhouse during his time there. Ditto for Realmuto, who is in the final year of his five-year, $115.5 million pact. Entering his age-32 season, Schwarber has been very productive during his first three years with the Phillies, averaging 44 home runs and 101 RBIs while playing 155 games per season. Realmuto’s offensive numbers pale in comparison, but his work behind the plate has been stellar, and with no catching prospects close to being ready for the Majors, the Phillies could look to keep Realmuto in Philly. Whether Philadelphia will try to lock up both players -- especially since signing Schwarber would clog up the DH spot for the immediate future -- remains to be seen, but both are legitimate extension candidates.

Adley Rutschman, C, Orioles, age 27
Eligible for free agency after the 2027 season

Rutschman has helped set the tone for Baltimore’s young core since he debuted in 2022, and even with a slight decline in his offensive numbers last season, the switch-hitter remains the backbone of the young club. While fellow youngsters Gunnar Henderson and Jackson Holliday are represented by Scott Boras, who famously prefers to take his clients to free agency, Rutschman is repped by Wasserman, which has negotiated extensions for a number of prominent clients. The Orioles haven’t been overly aggressive in free agency, but if new owner David Rubenstein uses his financial wherewithal to keep the club’s core intact, Baltimore should remain competitive for years to come.

Kyle Tucker, OF, Cubs, age 28
Eligible for free agency after the 2025 season

The Cubs traded three players -- Isaac Paredes, Hayden Wesneski and Top-100 prospect Cam Smith -- for Tucker, who is slated to become a free agent at the end of the season. Chicago would love to lock up Tucker with a multi-year deal, and given the club’s payroll situation -- Dansby Swanson is the only player on the roster signed beyond 2027 -- there should be ample flexibility to pay Tucker. The biggest question is whether the three-time All-Star has his sights set on testing free agency next offseason, though the Cubs will likely try to get a deal done before he reaches that point.
