I feel sorry for Ai Sugiyama
If the pattern is followed Serena will be focused and come out firing. In the slams, when Venus raises her game, Serena sees this and feels threatened, and comes out focused and determined to play better than Venus. She did this after Venus played 150% better in the AO 2003 second round. I don't know if she really feels that threatened by Venus or whether she is just using Venus for motivation (I think a little of both) Ai better be afraid, very afraid.
