(Reuters) - Defending champion Serena Williams cruised into the quarter-finals of the Western & Southern Open with a 6-0 6-2 win over Italy's Karin Knapp on Thursday while Swiss teenager Belinda Bencic's remarkable run came to an end.
Williams, who was upset by Bencic last week in the semi-finals of the Rogers Cup in Toronto, needed 54 minutes to get by Knapp and set up a showdown with Serbian Ana Ivanovic in what will be a rematch of last year's final.
"When you've done well somewhere it gives you confidence and also takes pressure off," said Williams, who has won 41 straight matches on U.
