The Boston Red Sox have made a significant move in the offseason by signing 16-year veteran reliever Justin Wilson to a one-year, $2.25 million contract for the 2025 season. Wilson, a left-handed pitcher from Clovis, California, has had a journeyman career in Major League Baseball, playing for eight different organizations. His extensive experience and versatility are expected to bolster the Red Sox bullpen in the upcoming season.
Career Overview
Justin Wilson began his MLB career in 2012 with the Pittsburgh Pirates and has since played for the Detroit Tigers, New York Yankees, Chicago Cubs, New York Mets, Cincinnati Reds, and San Francisco Giants. Throughout his career, he has accumulated a 3.52 ERA and 1.28 WHIP, with 10.1 strikeouts per nine innings. Wilson’s ability to pitch in various roles, including as a setup man and closer, has made him a valuable asset to multiple teams.
2024 Season Performance
In the 2024 season, Wilson pitched for the Cincinnati Reds, appearing in 60 games and totaling 46.2 innings. He posted a 5.59 ERA, allowing 51 strikeouts and 13 walks, with a concerning 10 home runs allowed. Despite these challenges, Wilson’s 38.8% chase rate was elite across baseball, driven by a cutter with significant vertical movement and a slider that ranked among the top 50% of relievers in Stuff+. His four-seam fastball, however, was less effective, contributing to the high home run rate. citeturn0news1
