Former World No 1 and sixth seeded Caroline Woznaicki of Denmark takes on Russian Anastasia Pavlyuchenkova in the pre-quarterfinal clash of the Cincinnati Open.

World No.8 Caroline Wozniacki has not had the best year so far with a win-loss record of 28-15. She is still in the hunt for her first title of 2012. With some really bad losses to her lower ranked opponents, Wozniacki has seen a dip in her ranking, which was No.1 when this year started. Her performance at Wimbledon recently was nothing great as she lost in the opening round. But since then she has bounced back strongly as he reached the quarter-finals in Olympics and last week reached the semis of Rogers Cup.

Her opponent: Pavlyuchenkova has poor 16-20 win loss record this year and has failed to progress beyond quarter-finals in all the tournaments she has played in except for Eastbourne and Bastad

Both the players have met five times before and Wozniacki has won each of them.
