All four quarter final matches were set for Friday at the Olympic Stadium in Moscow. First up was the defending champion Dominika Cibulkova of Slovakia against Caroline Wozniacki of Denmark, who got a wild card into this tournament. Cibulkova was seeded 5, while Wozniacki was the number 3 seed. Wozniacki’s newfound aggression, courtesy of her relatively new coach, saw her take the first set relatively easily, six games to two, but in the second set Cibulkova started to find her range and the set went all the way to a tie breaker, which the Slovak won on the trot, seven games to one. At 1-2 down in the decider, Cibulkova had a medical time out for treatment to her leg and she did not win another game in the set. Wozniacki will face off against Swede Arvidsson who took out the home favourite Kirilenko in the other bottom half of the draw semi.
Maria Kirilenko had some very raucous support from one particular fan during her match against the unseeded Sofia Arvidsson, who had an easy time defeating a lacklustre Marion Bartoli, the number 2 seed, in the second round. Throughout her match with Kirilenko she remained as cool as a cucumber, a la countryman Bjorn Borg, as the partisan spectators never applauded any of her great points. In the first round, Kirilenko came back from set point down in the first set to finally defeat Elena Vesnina in straights. In the second round she rallied from 1-5 down in the first set against Yaroslava Shvedova, to come out on top, again in straight sets. The quarter final match seemed a step too far for the Russian, as Arvidsson broke in the fifth and ninth games to take the first set 6-3. In the second set she raced to a 3-0 lead before Kirilenko got on the scoreboard and then broke the Swede to trail 2-3, but Arvidsson held her nerve and her serve and broke again before Kirilenko held for 3-5. In the final game Kirilenko lead 40-0 and advantage, but Arvidsson pulled back and took game, set and match on her 4th matchpoint.
