Beckham to undergo surgery for wrist fracture

What was thought to be simple nerve irritation for White Sox second baseman Gordon Beckham turned out to be a fractured hamate bone in his left wrist, which will require surgery and sideline him for about six weeks.

Beckham injured himself swinging at a 2-1 pitch from Gio Gonzalez during the second inning of Chicago's 8-7 loss to the Nationals on Tuesday. He left the game and was not expected to even pick up a bat until Friday.

Beckham said Wednesday that he woke up and didn't feel much better, but was taking anti-inflammatories. At that point, Friday was the best-case scenario. He had been going through hot-and-cold contrast treatment and working with White Sox head athletic trainer Herm Schneider the last few days.

In the meantime, White Sox manager Robin Ventura said he intends to use a mix of Conor Gillaspie, Angel Sanchez and Jeff Keppinger between second and third base.

Beckham was hitting .316 with a run, an RBI, a walk and five strikeouts this season.
