The Chicago White Sox agreed to terms Tuesday with left-hander Sean Newcomb on a one-year, $4.5 million contract.

Newcomb, 32, posted a 2-5 record with two saves and a 2.73 ERA in 48 games (five starts) last season split between the Boston Red Sox and Athletics. The Massachusetts native began his season in Boston before being traded to the A’s on May 27 in exchange for cash considerations.

Newcomb is 30-30 with four saves and a 4.20 ERA in 223 career appearances (65 starts) for the Atlanta Braves (2017-22), Chicago Cubs (2022), Athletics (2023-25) and Red Sox (2025).

To make room for Newcomb on the 40-man roster, the White Sox designated left-hander Ryan Rolison for assignment.

Rolison, 28, was claimed off waivers from Atlanta on Dec. 12. He went 1-0 with a 7.02 ERA in 31 appearances (one start) last season with the Colorado Rockies.
