Stats are not that great (4 DF's, 20+ UE's), but still a huge acomplishment! It wouldn't surprise me if she'd cancel, or at least tank, her doubles match after this. She needs to preserve her energy as much as possible, and with Wimbledon scheduling it's better to be safe than sorry.
The match that was scheduled before Donna's double match is over so in 10-15 minutes Donna could start her 1st round doubles match but I don't see how could they finish it today, they have a light till cca. 9:45 PM (cet)...will they even start?
