Connor Wong had a carpal boss excision surgery performed on his right hand Thursday.

According to the Cleveland Clinic, a carpal boss is a bony overgrowth or lump on the back of the hand or wrist. The problem might have contributed to Wong’s downfall this season, as he went homerless while batting .190//262/.238 in 188 plate appearances. Although he’ll be relatively inexpensive as a first-time arbitration-eligible player, here’s a good chance the Red Sox will move on from him this winter.
