Meanwhile Serena Williams, still looked rusty and error-prone in her 6-4 6-1 win against Angelique Kerber on Tuesday and repeated the sketchy performance on Wednesday in her 7-6(1) 6-3 win against Li Na. In both matches, the "best serve in women's tennis" was nowhere to be seen, with Serena barely placing half of her first serves into the court.
Serena's next match will be against World #1 Victoria Azarenka who won a classic barn burner against Kerber, saving two match points in a 6-7(11) 7-6(2) 6-4. Azarenka served for the 2012 U.S. Open championship against Serena at 5-4 in the 3rd set but ended up losing that match. Since then Serena has been off the tour entirely while Vika is on an 11-match, two tournament winning streak.
Serena was asked about the match-up with Azarenka and said:
It should be a great match on Thursday, even though Serena has nothing to lose because she has already qualified for the semifinal round. Azarenka needs one more round-robin win to clinch the year-end #1 ranking, and if she also reaches the semifinals, the two would meet again this week in the final, the very last official WTA tour match of the year.
