Fantasy Impact
Martinez will get his first action in the big leagues in 2025 after posting a 3.71 ERA and 1.26 WHIP across 43.2 innings out of the bullpen with Triple-A Jacksonville. He will likely be used in low-leverage situations early on.
The Marlins designated right-hander Seth Martinez for assignment Wednesday.
Fantasy Impact
Martinez's stint in Miami was short-lived, lasting less than two weeks after being claimed off waivers from Seattle on March 15. The Marlins cleared his roster spot to make room for newly acquired righty Tyler Phillips. Martinez appeared in 52.2 innings with the Astros last season, posting a respectable 3.59 ERA and 1.27 WHIP in a middle-relief role. Given his MLB experience and serviceable production, the 29-year-old could draw interest on waivers once again.
The Marlins claimed Seth Martinez off waivers from Seattle on Saturday, per team updates, returning him to Miami less than two weeks after his initial departure.
Fantasy Impact
Martinez, back with the Marlins Saturday, struggled this spring, yielding four runs in two-thirds of an inning, but his career 3.93 ERA offers bullpen hope. The 30-year-old righty could stick in Miami’s relief mix. Fantasy managers in deeper formats might consider him a low-risk stash for potential steady outings if he rebounds.
