to Somdev; I watched the match live and since Del Potro is right-handed and can still afford to play the back-hand without the left wrist, I do not know how it could have caused him any trouble. Moreover, this is the first round, no falling... He has been known to make excuses whenever he is not playing to his potential or making unforced errors. All credit to Somdev for targeting del Potro with low shots and back-hands.
