Wimbledon champion Petra Kvitova became the highest seed to exit the Indian Wells WTA tournament after a 2-6, 6-2, 6-3 loss to American teenager Christina McHale in the third round.
The third-seeded Czech breezed through the opening set at the Indian Wells Tennis Garden but errors began creeping into her game and her 19-year-old opponent took control.
McHale, making her third appearance in the elite event, broke Kvitova in the fourth game of the final set and again in the eighth when the Czech finished with successive double faults.
Serving for the match at 5-3, McHale burst into a 40-0 lead and then sealed victory at the first opportunity, ending a lengthy rally with a delicate sliced backhand into the front court.
Meanwhile, Men's third seed Roger Federer defeated wild card Denis Kudla 6-4, 6-1 in the second round of the ATP/WTA Indian Wells tournament on Sunday.
Federer hammered eight aces and won 79 percent of his first serve points in the 57 minute night match on centre court.
Federer advances to the third round where he will face Canadian Milos Raonic, who beat Carlos Berlocq in straight sets 6-4, 6-2.
