Juan Martin del Potro is preparing to undergo surgery on his left wrist by Monday, reports the Argentine press.
The Argentine has been struggling with ligament problems in the wrist, which affected him at the Australian Open and subsquent tournaments. He pulled out of singles in Indian Wells and withdrew from Miami despite receiving treatment between the two events. This lack of improvement appears to have led to the decision to have the surgery, which could keep him out for the rest of the season.
The surgery will be done by Richard Berger of the Mayo Clinic, who also performed a similar procedure when del Potro experienced problems with his right wrist in 2010.
