No. 8 Juan Martin del Potro withdrew from the Sony Open with a left-wrist injury that has bothered him for weeks.

Del Potro received treatment after pulling out of the BNP Paribas Open two weeks ago and flew to Miami to test the wrist in hopes of playing this week at the Masters 1000 tournament in Miami. But the 25-year-old Argentine decided that he wasn't ready to return.

"[I] still feel pain in my left wrist and I don't feel competitive to go on court," Del Potro wrote on Facebook. "It's a pity because this is a special tournament for me since there are many Latin fans and Argentines in particular. In the next few days I will visit my doctor again to determine the following steps."
