Connelly Early Delivers Historic 11-Strikeout Shutout in Dazzling Red Sox MLB Debut

Boston Red Sox prospect Connelly Early made a historic MLB debut on Tuesday, September 10, 2025, pitching five scoreless innings in a 6-0 victory against the Athletics. The 23-year-old left-hander, promoted from Triple-A Worcester due to pitching depth issues, allowed just five hits and one walk while striking out an impressive 11 batters. Early's dominant performance, featuring a filthy sweeping curveball and a mid-90s fastball, saw him strike out 52 percent of the batters he faced. His 11 punch-outs tied Don Aase for the most ever by a Red Sox pitcher in a debut and placed him in elite company alongside Hall of Famer Juan Marichal as one of only three players in MLB history to allow zero runs and one or fewer walks while striking out 10 or more in their first big-league game. This outing marked a personal best for Early, surpassing his previous high of 10 strikeouts in any game since high school, securing him a spot in the Red Sox's rotation.
