The Marlins announced that they have claimed right-hander Seth Martinez off waivers from the Diamondbacks. The latter club had designated him for assignment earlier this week. To open a roster spot, the Marlins transferred right-hander Eury Pérez to the 60-day injured list. Pérez is recovering from Tommy John surgery and isn’t expected back until around the All-Star break.
It’s the second waiver claim of the offseason for the 30-year-old Martinez. The Astros put him on waivers at the start of November, just as the offseason was getting going. The Snakes claimed him and kept him for a few months, but he got nudged off their roster when they signed Kendall Graveman a few days ago.
His entire big league track record has been with the Astros thus far. That club added him to their roster late in 2021. He got a cup-of-coffee MLB debut that year, then spent the past three seasons as an up-and-down depth arm for Houston. From his initial selection to the 40-man until being put on waivers, the Astros optioned him 12 times.
In between those trips to Sugar Land, he threw 137 1/3 major league innings for the Astros, allowing 3.93 earned runs per nine. He struck out 20.7% of opponents and gave out walks 9.2% of the time, marks just a bit worse than league average.
His minor league numbers have been a bit more intriguing. He logged 105 innings on the farm over the past four years with a 2.66 ERA. His 10% walk rate in that sample was still a tad high but he paired it with a strong 31.5% strikeout rate.
However, he exhausted his final option year in 2024, meaning he could no longer be freely shuttled to Triple-A and back. That’s why he has twice been put on waivers in the past few months and why he has been claimed today.
The Astros and Diamondbacks are clubs with competitive aspirations, so keeping Martinez in a big league spot would be a bit more tricky. The Marlins should find it far easier, however. As part of their rebuild, they have aggressively sent out players with big league experience, with the bullpen being no exception. Tanner Scott, A.J. Puk, Bryan Hoeing, Huascar Brazobán and JT Chargois were traded at last year’s deadline. Anthony Bender is now the only reliever on the roster with even three years of big league experience.
Before this move, Andrew Nardi was the only other guy over the two-year service mark, but Martinez now joins him in that camp. Though he’s out of options, Martinez could hang onto a spot in Miami’s bullpen if he’s pitching semi-effectively, given the lack of proven options. Most of the other guys in the relief mix are optionable. He should get a chance to post numbers more in line with his minor league track record. If he holds a spot all season, he can theoretically be retained via arbitration through 2028.
