Red Sox, Seth Martinez Agree To Minor League Deal

The Red Sox agreed to a minor league contract with reliever Seth Martinez, as first reported by Andrew Parker of Sox Prospects. He’ll get a non-roster invitation to MLB camp.

Martinez has pitched in the majors in five straight seasons. He got a decent amount of run in the Astros’ middle relief corps from 2022-24. He didn’t get as much big league work last year, only making it into six games for the Marlins. Martinez gave up four runs with three walks and four strikeouts across 6 2/3 innings.

The 31-year-old righty spent the majority of the year with Miami’s Triple-A club. He pitched to a 3.71 ERA behind a 29% strikeout rate over 43 2/3 frames. Martinez routinely posts strong whiff numbers in the minors and has fanned more than 30% of opponents with a sub-3.00 ERA in five Triple-A seasons. His flat 4.00 earned run average and 20.5% strikeout percentage in 117 MLB appearances are more solid than great.

Martinez only sits around 90 MPH with his fastball. He frequently relies on his breaking ball while mixing in a changeup. He’s out of options, meaning the Sox would need to keep him on the big league roster or expose him to waivers if they call him up at any point.
