A few days after officially announcing their first batch of non-roster invites to spring training, the Red Sox added another Friday.
Boston agreed to a minor league deal with veteran pitcher Seth Martinez and he will be in big league camp next month, a source confirmed Friday. SoxProspects’ Andrew Parker first reported the agreement.
Martinez, 31, has made 117 big league appearances (all in relief) since debuting in 2021 and spent much of three years in Houston’s bullpen. In total, he has a 4.00 ERA and 126 strikeouts in 144 big league innings. Martinez made at least 29 appearances for the Astros in each season from 2022 through 2024 and pitched especially well in 2022, a year in which Houston won the World Series.
Martinez’s tenure with Houston ended last November when he was exposed to waivers and he spent time in three organizations (Arizona, Miami and Seattle) during the winter. In mid-March, he was re-claimed by the Marlins, with whom he spent 2025. Martinez logged a 5.40 ERA in six big league appearances (all in the season’s final month) and pitched to a 3.71 ERA and striking out 54 batters in 43 ⅔ frames for Triple-A Jacksonville.
Martinez seems ticketed for a spot in Triple-A Worcester, where he’ll serve as bullpen depth in 2026. He joins pitchers Osvaldo Berrios, Alec Gamboa, Hobie Harris, T.J. Sikkema and Devin Sweet as pitchers who have joined the club on minor league deals in recent weeks.
