Less than a month away from pitchers and catchers reporting to spring training, the Miami Marlins pitching staff isn’t any stronger than it was when the 2025 season ended. Yes, they made a big investment in closer Pete Fairbanks, but they also found out that Ronny Henriquez would miss all of 2026 due to injury. Then they traded Edward Cabrera for a package that included only position players.

Improvement is still very possible as a wave of talented pitching prospects headlined by Thomas White and Robby Snelling gets ready to graduate to the big leagues. However, it’s risky to rely too much on rookies. Using Cabrera himself as an example, the former Top 100 MLB prospect was ineffective in his debut season—he didn’t really put it all together until his fifth season with the Marlins.

A source told Fish On First that although the Marlins would be content with their starting pitching depth, signing a veteran innings eater to a short-term deal has not been ruled out. Also, there has yet to be anything done to address the club’s left-handed reliever shortage.

With that in mind, the following free agents could be important, cost-effective pick-ups.

 

RHP Zack Littell

Littell, 30, was acquired by the Tampa Bay Rays as a waiver claim in 2023 when Peter Bendix was their general manager. Littell’s previous teams had been using him out of the bullpen, but the Rays converted him to a starter. The experiment paid off as the right-hander made 65 starts in parts of three seasons in Tampa Bay, posting a 3.68 ERA in a total of 376 ⅔ innings pitched.

Last season, Littell split his time between the Rays and the Cincinnati Reds. He handled by far the heaviest workload of his career (186.2 IP), posting a 3.81 ERA, 4.88 FIP, 6.27 K/9 and 1.54 BB/9. His walk rate ranked in the 98th percentile of MLB pitchers, per Baseball Savant.

Littell’s four-seam fastball has below-average velocity (92.1 mph). He also throws a slider, split-finger, sinker and sweeper. He pitches to contact, but ranked only in the 43rd percentile in ground ball rate. It is a weird but successful profile—he’s been worth 5.0 fWAR since the Rays helped turn his career around.

Littell allowed 36 home runs in his 32 starts last season. His ERA would probably rise in 2026 if that happens again, but the Marlins can offer him a more pitcher-friendly environment compared to his previous homes (Steinbrenner Field and Great American Ball Park).

In Miami, Littell would be the fourth or fifth starter in the rotation. Our own Louis Addeo-Weiss explained why Lucas Giolito is another potential option to fill that role.

 

LHP Martin Pérez

In 2025, Pérez pitched with the Chicago White Sox, making 10 starts (11 appearances), posting a 3.54 ERA, 4.24 FIP, 7.07 K/9, 3.54 BB/9 through 56 innings pitched. It was unusual for the southpaw to spend that much time on the injured list—he threw more innings in each of the 10 previous seasons.

Pérez’s sinker continues to be his best pitch, with a run value of plus-seven. He throws his changeup to both lefties and righties and still misses bats with it at age 34.

Having finished the season on the IL with a shoulder strain, perhaps Pérez would be available to the Marlins on a minor league deal. He would be the oldest player in camp.

 

LHP Jalen Beeks

On the reliever side of things, Jalen Beeks also crossed paths with Bendix while both were with the Rays. About two-thirds of Beeks’ career innings have come with that organization.

In 2025 with the Arizona Diamondbacks, Beeks had a 3.77 ERA, 4.01 FIP, 7.38 K/9 and 3.14 BB/9 in 61 appearances. He had a 46.3% ground ball rate this past season, the second-highest of his career. His changeup is his best pitch, generating a 35.2 whiff% and a dominant .110 wOBA against it. His arsenal also includes a four-seam fastball and cutter.

A one-year deal in the $5 million range should be enough to bring in Beeks as much-needed lefty bullpen help.
