The two punched and counterpunched their way to the brink of a first-set tiebreaker, but two loose errors from Kerber gave Williams two set points. A majestic backhand, deep and in the corner, was too good for Kerber to return. That unleashed a screaming Serena, who suddenly seemed to want this very much.With Williams serving the seventh game of the second, a break point -- the first of the match -- suddenly appeared. Serena's response was a 117-mph ace, followed by a 124-mph ace -- a quick end to any thoughts of giving in to Kerber.
Serena finished in a blur, winning the last eight points.
"I think I played what I could today," Kerber said in her postmatch interview. "I can just say, I mean, Serena was serving unbelievable today. At the end I was trying everything, but she deserved it today.
"Yeah, I mean, I think I was not the one who [lost] the match. I think she won the match."
