Serena feels the pain of ace display Czech out

SERENA WILLIAMS revealed her record-breaking ace count is giving some cause for concern after out-muscling gutsy Czech Petra Kvitova to advance to her sixth Wimbledon final on Centre Court yesterday.

Williams has sent down what in the women’s game is an unprecedented 80 untouched serves in the tournament so far and her booming assaults ultimately made the difference against Kvitova as she recovered an early break to win 7-6 (7/5) 6-2.

But that power has come at a price after Williams needed her shoulder taping during a doubles defeat alongside sister Venus on Wednesday. Williams joked: “I hit too many aces so my shoulder was done.”
