Red Sox Expected to Debut Kyle Harrison from Rafael Devers Trade

The Boston Red Sox are set to call up left-handed pitcher Kyle Harrison, a key player acquired in the June trade that sent Rafael Devers to the San Francisco Giants, to make his Major League debut in Wednesday's series finale against the Cleveland Guardians. Harrison has performed well at Triple-A Worcester with a 3.65 ERA in 11 starts and has recently improved his stats, making him the top candidate to start in place of rookie Payton Tolle, who is being given extra rest. Manager Alex Cora has not confirmed the move but acknowledged multiple options are being considered for the start, including a bullpen game. Harrison, who had a challenging start to the 2025 season with the Giants but was their No. 1 prospect prior to his MLB debut in 2023, has shown potential to provide a boost for the Red Sox rotation. Meanwhile, other players from the Devers trade, like reliever Jordan Hicks, have struggled, highlighting the importance of Harrison's upcoming performance. The Red Sox are managing their young pitching talent carefully, with Harrison potentially making more than one start to help ease the workload on Tolle as they push toward the season's end.
