The Boston Red Sox have signed 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, where he has maintained a 2.63 ERA since 2010.

In 2024, Chapman posted a 3.79 ERA with the Pittsburgh Pirates, showcasing his signature fastball with speeds over 100 mph. The Red Sox are looking to improve their struggling bullpen, which ranked 24th in the majors last season.
