He looks tired (although not as tired as DelPo). Win or lose - or should I say - when he wins, I would not be surprised to see him withdraw from Cincinatti.
Am I right in thinking this is the first time anybody has defended an Olympic Gold? In singles at least?
Poor Del Potro looks completely done. What an effort from him, he deserves the plaudits too. Astonishing match really, so much drama and tension.
