The Chicago White Sox and left-handed starting pitcher Martin Perez finalized a one-year, $5 million contract on Tuesday.
The deal includes a mutual option for 2026.
Perez, 33, joins his fourth team in three seasons after splitting 2024 between the Pittsburgh Pirates and San Diego Padres. Pittsburgh dealt him to San Diego at the trade deadline.
Perez was a first-time All-Star in 2022 with the Texas Rangers, when he pitched to a career-best 2.89 ERA with a 12-8 record and one shutout in 32 starts. He went 10-4 the next year as a part-time starter and helped Texas win the World Series.
In 314 career appearances (269 starts) with the Rangers (2012-18, 2022-23), Minnesota Twins (2019), Boston Red Sox (2020-21), Pirates and Padres, Perez is 90-87 with a 4.44 ERA, 1,109 strikeouts and 568 walks across 1,575 2/3 innings.
To make room on their 40-man roster, the White Sox designated right-handed reliever Ron Marinaccio for assignment. Chicago claimed Marinaccio off waivers from the New York Yankees in late September but he did not appear in a game for the White Sox.
