The Miami Marlins claimed right-hander Seth Martinez off waivers from the Arizona Diamondbacks on Thursday.
The Diamondbacks designated Martinez, 30, for assignment on Monday when they agreed to terms with right-handed reliever Kendall Graveman to a one-year contract.
Martinez has pitched parts of four seasons for the Houston Astros (2021-24), including a career-high 44 games in relief last season when he went 3-2 with one save, a 3.59 ERA, 18 walks and 36 strikeouts in 52 2/3 innings.
He is a career 6-6 with two saves, a 3.93 ERA, 54 walks and 122 strikeouts in 137 1/3 innings in 111 relief appearances.
The Astros waived him and the Diamondbacks claimed him on Nov. 4.
