ISTANBUL — When Serena Williams is serving at her best, no one stands a chance. Petra Kvitova experienced that the hard way today, when Williams put on a serving masterclass to blast past Kvitova 6-2, 6-3 to remain undefeated in round robin play and become the first woman to advance to the semifinals at the WTA Championships.
Behind 11 aces and 27 winners to just 13 unforced errors, Williams took all the air out of the highly-anticipated match-up between two of the biggest hitters in the women’s game, who also happen to be the last two winners of the WTA Championships.
Since the U.S. Open, Kvitova has lost just one match, and said she was relishing the opportunity to pit her game against the best player in the world. Aside from a few too many forehand errors, the 23-year old Czech didn’t play a bad match, hitting 17 winners to 19 unforced errors, a stable count given her low-margin game. But it seemed every time she earned a break point — she earned four for the match — Williams responded with an unreturnable serve.
