Olympic Tennis

Serena Williams and Roger Federer are both in the Olympic tennis finals. It will be interesting to see if they both can repeat their victories at Wimbledon a few weeks ago. Roger has had some close matches, including the last one which he won 19-17 in the third set. He will also be playing Andy Murray again, so all of Great Britain will be rooting against him. Serena's opponent will be Maria Sarapova, so she'll have her hands full, too.
