Williams makes it 15-15 on her service game with a cross court forehand that Muchova can hardly get a racket on, never mind direct the ball back into the court.
Muchova fires a forehand well outside the baseline and Williams moves 40-15 up.
A double fault gives Muchova another opportunity at 40-30, and the game goes to deuce.
Williams takes the advantage as Muchova fires a backhand into the net, but the advantage swings the other way courtesy of a double fault.
Set point is saved by a big serve from Williams, but Muchova carves out another, and that one she does take after another double fault!
