Venus began yesterday's final with a forehand error and finished the match with a forehand error, and I think it is all mental. Venus just needs to get more confidence when playing Serena, go more for her shots and make less tenative, silly errors. For a long time, I thought that Venus' problem was that she didn't want enough to win and that she was loosing her inensity - remember how she used to grind her teeth and grunt when she was playing for her first Grand Slam title. But today the intenisty and the will to win were definetely there but her game crumbled under pressure. I have also never seen Venus be so negative during a match. With every loss to Serena it gets harder for her to defeat her sister, but her attitude after the match seemed positive.
