The Boston Red Sox have strengthened their bullpen by signing left-handed reliever Aroldis Chapman to a one-year deal worth $10.75 million. This marks Chapman's seventh team in his 15-year career, during which he has maintained a 2.63 ERA since his debut in 2010.

Despite a 3.79 ERA in 2024 with the Pittsburgh Pirates, Chapman's exceptional velocity and strikeout rate make him a valuable addition. The Red Sox aim to improve their bullpen, which ranked 24th in the majors last season.
