I think Serena realizes her mistakes far more than we think she does, and I am not saying she didn't want to win this tournament of course she did. She has to get her serve back in sync that is where her confidence in her game lies, and it hasn't been there since her Wimbledon loss. It has been very hit or miss. Having said that, confident Vika or no, Serena will go into the open motivated. Last opportunity to pick up another slam. While Vika has two wins over Serena this year, they weren't easily accomplished wins over her. I don't think Serena is going to worry until Vika beats her 6-1, 6-1. The intangibles still fall in Serena's favor there.
