Even if she loses her next matches, Hingis is guaranteed a paycheck of $13,250, which brings her yearly earnings to $2,008,734. Hingis passes Lindsay Davenport, who withdrew this week for the Toyota Princess Cup in Tokyo, for second place on the prize money leaders.
Venus Williams, who also is not playing this week, leads all players with $2,030,650.
Hingis has been the WTA Tour's prize money leader for the last three years.
