World No. 8 Juan Martin del Potro withdrew from the Sony Open on Wednesday with a left wrist injury that has plagued him since the Australian Open in January.
The ailing wrist forced Del Potro to retire from a first-round match against Somdev Devvarman at the Dubai Duty Free Tennis Championships two weeks ago. He also did not compete at last week's BNP Paribas Open in Indian Wells, Calif.
