Angelique Kerber ended the 19-match win streak of Wimbledon and Olympic champion Serena Williams with a 6-4, 6-4 victory in the quarter-finals of the ATP and WTA Cincinnati Masters tournament on Friday.
The German fifth seed double-faulted on one match point but concluded with a winning ace on another to send the second seed out of the event, one that Williams has never won. It was the opposite story for elder Williams sister Venus, who upset defending US Open champion Samantha Stosur of Australia 6-2, 6-7 (2/7), 6-4. China’s Li Na reached the semi-finals over top seed Agnieszka Radwanska 6-1, 6-1 as the Polish favorite struggled with a shoulder injury.
Czech Republic’s Petra Kvitova beat Russian Anastasia Pavlyuchenkova 6-3, 7-6 (7/4) to book her spot in the last four. Federer, Djokovic advance Meanwhile, World No 1 Roger Federer moved closer to a fifth Cincinnati Masters crown as the Swiss star crushed American Mardy Fish 6-3, 7-6 (7/4) to reach the semi-finals.
Federer, seeking his sixth title of the year, was in regal form as he beat Fish for the eighth time in nine meetings. Federer will line up against compatriot Stanislas Wawrinka after the Swiss stormed back to beat Canadian Milos Raonic 2-6, 7-6 (7/5), 6-4, in another quarter-final. US Open champion Novak Djokovic also booked a semi-final with Olympic bronze medalist Juan Martin del Potro by beating Marin Cilic 6-3 6-2
