Marlins Designate Seth Martinez For Assignment

By Darragh McDonald | September 11, 2025 at 2:10pm CDT

The Marlins announced that left-hander Ryan Weathers has been reinstated from the 60-day injured list, a move which was previously reported. In a corresponding move, right-hander Seth Martinez has been designated for assignment.

Martinez, 31, had some decent run with the Astros earlier in his career. Over 2022 and 2023, he gave Houston 81 2/3 innings, allowing 3.75 earned runs per nine. His 23.7% strikeout rate and 9.4% walk rate were both close to league average. But last year, his strikeout rate dropped to 16.2%. He was sent to the minors a few times, exhausting his final option season.

He was therefore out of options heading into 2025, which gave him a tenuous hold on a roster spot. But given his past success, he still had enough appeal to bounce around the league. In the offseason, he went to the Diamondbacks, Marlins, Mariners and Marlins again via a series of waiver claims. The Fish put him on waivers again around Opening Day, when he finally cleared.

He has therefore spent most of this year pitching in Triple-A. He logged 43 2/3 innings for Jacksonville with a 3.71 ERA, 28.9% strikeout rate and 9.6% walk rate. He was called back up to the big leagues about two weeks ago. Between then and now, he tossed 6 2/3 innings for the Marlins, allowing four earned runs via four hits and three walks while striking out four. It appears that wasn’t enough to get him beyond the fringes of the roster, so he’s been bumped off today.

With the trade deadline having passed, Martinez will have to be on waivers yet again in the coming days. He won’t have much short-term appeal to clubs, since he wouldn’t be postseason eligible for any claiming team. But he can be controlled for four seasons beyond this one since he has less than three years of service time. Given the notable interest he garnered in the offseason and his recent uptick in strikeouts in the minors, perhaps there’s a team intrigued enough to make a claim. If such a team exists, they could get a close-up look at Martinez in the final few weeks of the season as they decide about putting him in their 2026 plans.

    To this point, I cannot believe that Seth Martinez, the guy that brought us Family Guy and American Dad, isn’t worthy of a single comment.

    Kind of hope the cards put in a claim. Got a couple open spots in the pen. Roycroft has been terrible
