DEL POTRO 6-2 6-7(5) 6-2 6-1 - GAME, SET & MATCH - Impressive will from Del Potro as he forces himself through to the second round despite that knee injury (how bad it is, we just don't know). He comes up with an ace and a cracking serve out wide that Montanes can only return wide to seal the match and will face either Edouard Roger-Vasselin next, the Frenchman coming past Vasek Pospisil 3-6 6-3 6-2 6-2
