The Chicago White Sox continue reshaping their roster following the high‑profile addition of Munetaka Murakami. On Tuesday, the team announced it have agreed to terms with left-handed pitcher Sean Newcomb on a one-year, $4.5 million contract, adding another experienced arm to its pitching staff.

Newcomb, a former first-round pick, brings versatility as both a starter and reliever, giving Chicago another option as it continue restructuring its pitching depth heading into the new season.

The club confirmed the move on X, writing: “The Chicago White Sox have agreed to terms with left-handed pitcher Sean Newcomb on a one-year, $4.5-million contract. To make room for Newcomb on the 40-man roster, the White Sox designated left-hander Ryan Rolison for assignment.”

Roster implications for the White Sox

Designating Ryan Rolison for assignment was a necessary move to make room for Newcomb on the 40-man roster. Rolison, who had a brief stint with the White Sox, now faces the uncertainty of waivers or potential release, highlighting the competitive nature of roster management during the offseason.
