Berdych thru', Wawrinka out

Czech Republic number one Tomas Berdych is one win from sealing his ticket to the World Tour Finals after easing into the quarterfinals of the Paris Masters on Thursday.

Following a first round defeat at the Valencia Open last week, the 29-year-old Berdych evened his record against Spaniard Feliciano Lopez at six wins apiece with a 7-5, 6-3 victory behind the back of a 70 per cent first serve percentage and eight aces.

Chasing an 11th ATP title, and third of the year, the Australian Open semi-finalist now plays South African 14th seed Kevin Anderson for a place in the semi-finals.

Victory for Berdych would guarantee his place in the eight man field in London which begins on November 9 although he could still qualify depending on results elsewhere.

Anderson won a marathon thriller over Swiss third seed Stan Wawrinka 6-7 (2/7), 7-5, 7-6 (7/3) in a match that lasted just under three hours.
