Zvonareva is the player to beat this weekend having remained unbeaten throughout the round-robin stages to top the White Group. She scored an impressive 6-4, 7-5 win over Kim Clijsters, her third win over the Belgian this year, and in doing so, secured the world number two ranking.
"I definitely produced some good tennis today," Zvonareva said. "Every tournament I go to I'm trying to do my best to win it. But I have to take it one match at a time."
Wozniacki recovered well from her shock straight sets defeat to Sam Stosur, to battle past Francesca Schiavone 3-6, 6-1, 6-1, sealing her place in the last four. The match was far closer than the scoreline suggested but it was Wozniacki's sheer grit and determination on the big points which made the difference in the end.
Wozniacki and Zvonareva are 3-3 on head-to-heads. They have enjoyed a burgeoning rivalry in 2010, they have already played four times with each player winning two apiece.
Zvonareva triumphed 6-4, 6-3 in the US Open semi-finals but Wozniacki won their matches in the Montreal and Beijing finals.
Prediction: Zvonareva to come through in three sets
