Martinez has declined his $6.5 million player option with the Padres for 2023, making him a free agent.
Martinez signed with San Diego on a one-year deal in December 2021 and posted a 3.47 ERA, 1.29 WHIP and 95:41 K:BB across 106.1 innings. The right-hander opened the campaign in the rotation before he was shifted to the bullpen, and he briefly served as the team's closer until Josh Hader got back on track.
