I see Kukushkin has just beaten Delpo and that Heather has beaten Vinci.
It was an extremely close match though, so Delpo really has done very well, better than even he expected - “I didn't expect to play three matches in a row in this tournament,” he said. “I just wanted to play my first round and see what happens. But I got lucky playing three matches in this tournament against good players. I'm still here. I'm still alive. I feel tired, but okay.”
With more time delpo will be back to his best
Time, plus staying injury free, and also his wrist hasn't really been fully tested yet, something playing four or five setters at the AO will do.
