Well, she made an awesome return after the injury. Its kind of normal to be a little rusty. And that shows up on decisive moments. I for one think she is doing a lot better than I would expect.
Stanford (TII) - semifinal lost in 3 sets to Clijsters
San Diego (TII) - semifinal lost in 2 sets to Venus
Los Angeles (TII) - final lost in 3 sets to Rubin
She won 9 matches (including Dokic and Rubin and Sugiyama twice) and lost three, all to great players.
She´s resting this week, and probably practicing on the flaws she´s showing. She should be fine for the USOpen!
