Cespedes recently underwent surgery to repair a hamate bone fracture in his left hand and will miss the rest of the season, Chris Hatfield of SoxProspects.com reports.
Cespedes had been expected to make his full-season debut with Single-A Salem in late June, but he suffered the hamate bone fracture while playing in the rookie-level Florida Complex League. The outfielder should be back to full health for the start of spring training.
