The Boston Red Sox and New York Yankees may have the best, most heated rivalry in all of baseball. In recent years, the San Diego Padres’ rivalry with the Los Angeles Dodgers has gained some steam, but it still doesn’t even come close to the hatred between the Rox Sox and the Yankees.

This winter, that rivalry extends into free agency as the two opposing teams have very similar targets, including Corbin Burnes and Juan Soto.

Before the Stars sign with either team, Boston has already signed a former Yankee, albeit a controversial one, to a one-year contract.

On Tuesday morning, Jon Heyman of the New York Post announced that the Red Sox had agreed to terms on a one-year deal with veteran flamethrower Aroldis Chapman. The deal is worth just over $10 million through the 2025 season.

Chapman pitched in the seventh or eighth inning for the Pittsburgh Pirates last year. He began his career with the Cincinnati Reds before moving to the Yankees, where he pitched nearly 300 innings over seven seasons. The flamethrower also played for the Texas Rangers, Kansas City Royals and Chicago Cubs during his 15 big league seasons.

Although he’s not the same arm he was in 2015, Chapman posted a respectable 3.79 ERA in 2024 while hitting triple-digit fastballs quite often.

What’s important to note here is that if Chapman gets more than $10 million per year, Kirby Yates, Blake Treinen and other candidates for one-year deals will cash in this winter.
