KEY BISCAYNE, Florida (AP) -- Two-time Key Biscayne champion Victoria Azarenka has withdrawn from the upcoming Sony Open because of a lingering foot injury.
Azarenka, who pulled out Wednesday, missed last year's tournament because of an ankle injury. She played for the first time in more than a month Friday and lost at Indian Wells to Lauren Davis.
Aside from the No. 4-ranked Azarenka, all of the top 10 players on the men's and women's tours are scheduled to compete at Key Biscayne.
Former No. 1 Martina Hingis will be given a doubles wild card with Sabine Lisicki. Hingis last played in the tournament in 2007.
The two-week event begins Tuesday.
