For the third match in a row 4th seed Agnieszka Radwanska had a real battle on her hands when she played the Belgian 30th seed Kirsten Flipkens. Radwanska had dropped a set in her two previous matches and on Tuesday this pattern repeated itself when Flipkens, playing her wonderfully varied game, broke the Pole twice to lead 4-1 in the first set. Radwanska fought hard, but Flipkens took this set 6-4. In the second set Radwanska took a 3-0 lead, but the Belgian battled back to level at 4-4 before the Pole went on a rampage and took the next seven games in a row to take the second set 6-4 and lead 5-0 in the decider. Flipkens then took two games, but Radwanska closed out the set at 6-2 to book her place in the semis, where she will take on Serena Williams in a repeat of the 2012 Wimbledon final.
Top seed Williams also had a tough match against Na Li, the 5th seed, in the other top half of the draw quarter final. She took the first set 6-3 in 42 minutes, an indication of how hard fought each game was. In the second set Williams broke for a 2-0 lead, but Li started to find her range and took the next five games in a row to lead 5-2, but the American surged back to level and the set went to a tie breaker which Williams took 7-5 to seal the win after almost two hours on court.
