Wimbledon: Russian struggling against world number one
Another Russian – number eight seed Anna Chakvetadze – is playing Michaella Krajicek of the Netherlands.
In today's other game, Ukranian Alona Bondarenko is a break down against Swiss Patty Schnyder.
Meanwhile Marat Safin will take on Roger Federer a little later on, on Centre Court.
The World number one is ahead 7-2 on previous head-to-head meetings, but Safin is looking forward to the challenge.
“Well, for me it is an opportunity to play a great match,” said Marat Safin.
Roger Federer is chasing his fifth successive Wimbledon title.
