I was at this match and Mary played great again. It was a real shame that they couldn't win the second set. Mary served for the match once, as did Tatiana. The real difference was that the others started playing as a team a lot more - Tatiana was staying back on her first and second serves which left Mary vulnerable at the net.
I wonder what this means for the Olympic doubles teams. I think Mary is a great doubles player, some of her volleys were outstanding but she needs a partner who is also confident at the net. Amelie would be the prefered choice but Mary and Tatiana were so great to watch I wouldn't mind seeing them play together again.
