Dubai: Top seed Caroline Wozniacki went crashing out of the 2010 Barclays Dubai Tennis Championships when she fell to Israel's Shahar Peer 6-2, 7-5 at the Dubai Tennis Stadium on Wednesday.
Peer, who knocked out last year's finalist Virginie Razzano on Tuesday and 13th seed Yanina Wickmayer in the first round, was in smooth flow on Court No.1 as she broke in the second, fourth and sixth games to take the opening set 6-2.
The second set was more engrossing as the top seed and World No.3 from Denmark fought back each time she was down.
Peer broke in third, only to see Wozniacki break back for 2-2 and then again it was on par at 4-4 and 5-5.
After a hard and lasting battle, the Israeli broke in the 11th and then held to outlast the top seed and become only the second player to enter the quarterfinals here.
Earlier, seventh seeded Agnieszka Radwanska belted her way to a first-ever win in four appearances in Dubai with a 6-3, 6-0 result against Italy’s Flavia Pennetta to also become the first one to book a quarterfinal berth.
It was advantage to the Italian as she broke for a 2-0 cushion, but Radwanska came right back to wrap up the set 6-3.
The Pole started strongly in the second for a 3-0 lead when Pennetta took a medical time-out to treat a lower back sprain.
Radwanska took her chance and broke one more time and then served out for set and match 6-0 in exactly one hour.
"Just winning for the first time gives me a great feeling," the Pole admitted. "I want to stay here till Sunday," she added.
