MLB Free Agents Chase October Moments to Boost Winter Value

October has a way of changing the temperature on a player’s winter. A reliever who gets three big outs, a starter who carries a club through the middle innings, or a hitter who finds one timely swing can leave a sharper final impression than a quiet September. More than three dozen impending free agents are headed into the postseason with that extra stage available, carrying everything from opt-out decisions and mutual options to comeback stories and unfinished October résumés.

October leverage for the bullpen market

The relief market has several established late-inning names, but postseason work can still determine whether a club sees a closer, a setup option or a useful depth arm.

Bryan Abreu, Astros: Abreu owns a 2.49 ERA in 21 career playoff appearances, including 10 scoreless outings during Houston’s 2022 World Series run. His strikeout ability travels, though a 15.3% walk rate remains a concern in tight games.
Jason Adam, Padres: Adam has posted a 2.13 ERA across 300 appearances with Tampa Bay and San Diego over the last five years. A shoulder strain cost him nearly three months, and his playoff record is limited to 7 1/3 innings with a 2.45 ERA over two postseasons.
José Alvarado, Phillies: Alvarado was barred from pitching last October, then endured an uneven 2026 before improving in mid-August. A couple of difficult late-September appearances complicated the finish, but this will be his fifth postseason.
Shawn Armstrong, Guardians: The 36-year-old has made one scoreless appearance in each of his two playoff trips with Tampa Bay, both Wild Card Series sweeps. Cleveland can use him in high-leverage spots, while his $8 million mutual option includes a $1.5 million buyout and likely sends him into free agency.
David Bednar, Yankees: Bednar recovered from a down 2024 with two excellent seasons and has returned to the top tier of available closers. In his first postseason last year, he recorded two saves with a 1.50 ERA, striking out nine and walking one in six innings over five outings.
Paul Blackburn, Yankees: Blackburn shifted from an ordinary starting profile into an important bridge reliever in 2026. His lone playoff appearance went poorly—four runs on six hits in 1 1/3 innings against Toronto in Game 1 of last year’s ALDS—but October offers a chance to reset that memory.
Raisel Iglesias, Braves: The 36-year-old re-signed for one year and $16 million, made his first All-Star team and again delivered a strong season. He has a 6.75 ERA in seven postseason appearances, although he blanked the Phillies in all three outings during the 2023 NLDS.
Evan Phillips, Dodgers: Since Los Angeles claimed him in August 2021, Phillips has become a dependable late-game option, logging a 2.36 ERA in 232 regular-season relief appearances across six seasons. He has thrown 15 1/3 scoreless innings in 12 playoff games from 2021-24.
Alex Vesia, Dodgers: Vesia has posted an ERA between 1.76 and 3.02 in every full season except 2023 since joining the Dodgers in 2021. His postseason ledger is a 1.86 ERA in 26 appearances over five Octobers; he missed last year’s World Series because of a family matter.
Garrett Whitlock, Red Sox: Whitlock has flourished as a full-time reliever since the beginning of 2025. He carries a 2.70 ERA across 10 playoff innings, though he was tagged for one run on three hits and two walks in 1 2/3 innings during last year’s Wild Card Series Game 2 loss to the Yankees.

Rotation questions, comeback cases and opt-out stakes

Several starters enter October with roles still unsettled. Some have been lined up for the ball, while others could work from the bullpen because their clubs have more rotation choices than games to start.

Matthew Boyd, Cubs: Chicago has not settled on Boyd’s October assignment. He has not relieved regularly since posting a 1.35 ERA in 10 bullpen outings for Seattle in 2022, when the Mariners also used him in his playoff debut. He owns a 1.69 ERA in six postseason starts over the last two years.
Walker Buehler, Padres: Buehler posted a 4.63 ERA and 88 ERA+ in his first San Diego season, but his 153 2/3 innings were his largest total since 2021. He has a 3.04 ERA over 19 playoff games, including 18 starts, and was part of Dodgers championship teams in 2020 and 2024.
Erick Fedde, White Sox: Fedde has worked as both starter and bulk reliever, starting 15 of 33 games while posting a 3.83 ERA in 141 innings. The 33-year-old is expected to be part of Chicago’s postseason rotation after a bounce-back year.
Kevin Gausman, Cubs: Gausman has discussed retirement, so October may carry a different kind of meaning. He reached Game 7 of the World Series with Toronto last year but has never won the title over 14 big-league seasons. His availability will hinge on recovery from left shoulder soreness suffered while diving for a ball.
Sonny Gray, Red Sox: Gray put together another strong 2026 season heading toward age 37 and should draw offseason interest. He owns a 3.26 ERA in six postseason starts, but has not completed more than five innings in any of his last five October starts, dating to 2013.
Foster Griffin, Guardians: Griffin went 12-3 with a 3.06 ERA in 22 Washington starts, then struggled after arriving in Cleveland, going 3-3 with a 5.19 ERA in nine starts. His first postseason appearance could be a significant part of his case for a multiyear contract.
Tyler Mahle, Braves: Mahle had a 5.13 ERA in 18 starts for the Giants, but has been outstanding since the trade to Atlanta, posting a 1.99 ERA in nine starts. He is slated to start Game 2 for the Braves.
Nick Martinez, Rays: Martinez is expected to turn down a $20 million mutual option after an excellent first Tampa Bay season. He led the Majors at 1.3 walks per nine innings, and all eight of his playoff appearances, a 3.18 ERA sample, have come in relief.
Dustin May, Brewers: Since returning from Tommy John surgery in 2025, May has a 4.82 ERA in 56 appearances, including 54 starts, after owning a 3.10 mark in 46 games before the injury. He posted a 5.65 ERA in 10 starts after Milwaukee acquired him, but could still receive a postseason rotation spot. His last October came with the 2020 champion Dodgers.
Freddy Peralta, Rays: A disastrous Mets stint hurt Peralta’s position, and his early Tampa Bay work was also rough. Since Aug. 26, however, he has looked like an ace, working to a 0.79 ERA in six starts. This will be his seventh postseason, though he has gone 1-3 with a 5.33 ERA in six appearances, five starts, since 2023.
David Peterson, Cubs: Peterson had a 6.09 ERA in 68 innings with the Mets before his June 25 move to Chicago. With the Cubs, he recorded a 3.70 ERA in 80 1/3 innings, though the club’s rotation depth could place him in the bullpen. He owns a 3.14 ERA in seven playoff appearances, one start.
Robbie Ray, Padres: Ray was dealt from Seattle to San Francisco two years into his five-year, $115 million contract, then pitched well enough in 2025-26 to become a San Diego Trade Deadline pickup. He turns 35 Thursday and reaches the market with a 7.43 ERA in six career postseason outings, including two starts.
Tarik Skubal, Dodgers: The two-time Cy Young Award winner’s market standing is already secure, but a longer October remains absent from his résumé. Skubal is 2-1 with a 2.04 ERA in six postseason starts, yet has never advanced past the Division Series.
Michael King, Padres: King set a career high in innings during a strong season and appears positioned to opt out of the final two years and $58 million on his deal. A strong postseason would reinforce that call; a rough one could prompt a different decision. He is 2-0 with a 3.00 ERA in four playoff games, two starts, and is entering his third straight October with San Diego.

Everyday players with something to prove

For position players, October can offer a short but valuable answer to questions about health, production, defense and whether a regular-season line travels into a high-pressure series.

Luis Arraez, Phillies: After a long trip through free agency, Arraez signed for one year and $12 million with San Francisco, made the All-Star team in the first half and was traded to Philadelphia at the Deadline. A sprained left ankle could affect his availability. He is batting .224/.246/.284 with one RBI in 17 playoff games and seeks the multiyear contract that escaped him last winter.
Jake Bauers, Brewers: Bauers set personal bests across the offensive board in his age-30 breakout. In eight postseason games with Milwaukee, he owns a .316/.350/.684 line and a 1.034 OPS, entering his third consecutive October with more expectation than before.
Alec Bohm, Phillies: Bohm drove in 88 runs, but his -0.2 bWAR was his lowest since 2021. He hit two homers and drove in 14 over 30 postseason games in 2022-23, then went without an RBI in eight games over the past two Octobers as Philadelphia exited in the NLDS both times.
Jazz Chisholm Jr., Yankees: Chisholm recently returned from a two-week injured-list stay and has not enjoyed the season he wanted before free agency. He is batting .170/.247/.295 in 24 playoff games, with three home runs and three RBIs over four October trips.
Mauricio Dubón, Braves: Dubón played 153 games while moving around Atlanta’s infield and outfield, giving manager Walt Weiss lineup flexibility. After never reaching 500 plate appearances with the Giants or Astros, he cleared 600 in his first Braves season. He is expected to play shortstop against left-handed starters and left field against right-handers.
Ty France, Padres: France’s one-year, $1.35 million agreement became one of winter’s strongest bargains. He produced 4.5 bWAR with an OPS above .850, his best all-around season since 2022. This will be his third postseason after appearances with Seattle in 2022 and Toronto in 2025, when he made the Blue Jays’ World Series roster without playing in a postseason game.
Randal Grichuk, White Sox: Released after a brief early-season Yankees stay, Grichuk joined Chicago in early May and crushed left-handed pitching for an OPS above 1.000. The 35-year-old should start against lefties and could see some right-handers as well. It is his fourth postseason and first since 2020.
Trent Grisham, Yankees: A right hamstring strain has sidelined Grisham since early September, leaving his Wild Card Series status uncertain. If New York reaches the Division Series, he could return as a center fielder or bench option. He has a .160/.275/.287 playoff line in 26 games, with three homers and seven RBIs.
Ian Happ, Cubs: The Gold Glove left fielder is headed to his fifth postseason but has advanced past the Division Series only once. Happ has batted .178/.245/.400 with three homers and five RBIs in 16 playoff games. Two of those home runs came against Milwaukee in last year’s NLDS, although he hit .105 in the five-game series.
Ha-Seong Kim, Braves: Kim’s one-year, $20 million season in Atlanta has been derailed by more than 100 games missed and negative offensive and defensive value. In his lone postseason, with San Diego in 2022, he hit .186/.286/.256 with three RBIs and 14 strikeouts in 12 games. A multiyear offer appears unlikely, but a solid October could still help him secure guaranteed money.
Nathaniel Lowe, Guardians: Lowe has not matched his Cincinnati output since the summer trade, though Rhys Hoskins’ injury pushed him into a full-time first-base role. Lowe hit three home runs and drove in six during Texas’ 2023 championship run, then went 1-for-7 while starting one game for Boston in last year’s Wild Card Series against the Yankees.
Cedric Mullins, Rays: Mullins has not recreated his 2021 30-30 breakout and .878 OPS, but he has still hit at least 15 home runs in each of the last five seasons while providing above-average center-field defense. He went 0-for-12 in the 2023 postseason and 3-for-7 with a homer in 2024. His $10 million mutual option is likely to be declined.
Seiya Suzuki, Cubs: Suzuki should be among the strongest bats in the upcoming class. He hit three homers and three doubles in eight playoff games last year, producing an .863 OPS against San Diego and Milwaukee.

Role players who can make the roster case in October

Not every free-agent decision will be made at the back of a bullpen or in the middle of an order. Versatility, matchup value and a willingness to handle unusual assignments can also become more visible in October.

Sean Newcomb, White Sox: Newcomb returns to the postseason for the first time since 2019 after appearing with Atlanta in back-to-back Octobers. The 33-year-old has filled nearly every pitching assignment for Chicago, from opener to closer, and should continue as a flexible postseason piece.
Shota Imanaga, Cubs: Imanaga reached a career-high 174 1/3 innings, while his 3.77 ERA nearly matched last year’s 3.73 figure. He could work in the Wild Card bullpen before shifting into the rotation if Chicago advances. In last year’s postseason debut, he went 0-1 with an 8.10 ERA in two appearances, including one start.

That is the October equation for this group. The regular-season record will remain the foundation of every negotiation, but the postseason supplies a final inning of evidence. For some, it is a chance to affirm a market already waiting. For others, it is a chance to leave the clubhouse with a cleaner last line than the one they carried into it.
