Basically she's like Nole this year. Not playing good but keep on winning
She's played well when she's needed to up against the brink, particularly at the French.
Serena played pretty well in the 2nd week of Wimbledon.
But this match tonight is entering the danger zone.
Mattek-Sands isn't going to give it to her, she's just going to keep hitting the ball back in the middle of the court.
Start hitting with more margin Serena.
Make Mattek-Sands hit a few balls.
This is as many break points as I've seen Serena waste in a long time.
