So, it's 5-0 to Ms Muguruza in the second set. She needs her service game to win*.
And the male American member of the commentary team has only just stopped going on about how great Ms Williams is. When she lost the first set, he said that set had been hers to win, & she looked as if she'd come back.
She looks worn out. Can't keep up.
PS. Won it, so second set 6-0.
PPS. I wonder if Garbiñe Muguruza pronounces that z as if she's Venezuelan, Castilian or Basque. S, the, or funny s?
