### Day 4

The 1st match of the last day of the round robin stage featured Jelena Janković and Caroline Wozniacki. The result had several implications on the outcome of the group. A Janković win and she topped it with Wozniacki in 2nd with Azerenka having a chance to leap frog the pair of them later. This would squeeze Wozniacki out of the tournament. However a Wozniacki win would see her top with Azerenka going through, without having to play.
The first set saw Janković only lose 5 points on serve, and broke Wozniacki twice to take the set 6–2. The second set was much the same with Janković breaking 3 times. Wozniacki did offer some resistance breaking once, but could not prevent herself losing the set, 6–2. For a 6–2, 6–2 win for Janković and top place in the group.
The next match featured Russians Elena Dementieva and Svetlana Kuznetsova. Dementieva needed to win the match to clinch a berth or Venus Williams and Kuznetsova would end up level with her. With the American going through on the tie break situation, unless Dementieva won in straight sets. Kutznetsova was looking to end her 8 match losing streak at the Championships. With nothing left to play for but pride, Kuznetsova re-discovered the kind of form that took her to the Beijing title at the beginning of October. Dementieva, looked tense from the start and was forced to save a break point in the second game. It didn't take long for another opportunity to go Kutznetsova's way when in the sixth game when her opponent double faulted twice. Dementieva saved two set points in the eighth game but Kuznetsova made no mistake behind her own serve, sealing the set 6–2. The second set followed much the same pattern, with Kuznetsova breaking in the opening game. The French Open champion secured a second break of serve in the fifth game when Dementieva went wide, before serving the match out. This win ended Kuznetsova's 10 match-losing streak, since her first win at the 2006 championship. Venus advanced to the semifinals following this result.
The last match in the round robin stage featured Agnieszka Radwańska who replaced co-alternate Vera Zvonareva and Victoria Azarenka. Azarenka needed to win to clinch the last semifinal place or it would go to Wozniacki. Azarenka appeared to be cruising to the straight sets win that would have seen her top the white group when she took a 6-4 5–2 lead over Radwańska. After Azarenka broke in the opening game and although Radwańska broke back in the second game, the opening game set the tone as the Belarusian broke again in the 5th and 6th games to race out to a 5–2 lead. Azarenka did suffer a minor blip in concentration towards the end of the first set as she allowed Radwańska one of the breaks back, it was only a temporary lapse as the Belarusian served it out at the second attempt. Azarenka ran away with match in the early stages of the second set, breaking in the first and third games. But the Pole, refused to give up and was rewarded for her patience when she broke back in the sixth game. Azarenka recovered her composure by immediately breaking back and setting up a chance to serve out the match. But the Belarusian undid all her good work with consecutive double faults to hand momentum back to Radwańska. The Pole raced through the next five games to seal the second set and level the match. The match was just one game into the third set when Azarenka was forced to take a medical timeout to have her left thigh heavily strapped. Three games later Azarenka was break points down and in tears after trying to race up the court to a drop shot. The Belarusian saved the first break point, but again she was left sobbing and kneeling on the ground next before going on to double fault and hand her opponent the break. One more medical timeout and one and a half games later and Azarenka decided she could not continue. Radwańska won 4-6 7-5 4–1, Azarenka retired due to cramp. The result meant that Janković topped the group with Wozniacki the runner up.
