Polish teen stuns Sharapova at US Open

The Russian glamour girl had won her opening two games, both played at night for the loss of just two games and had spent just 101 minutes on court.
She got off to a smooth start pushing the 18-year-old Pole onto the backfoot with her big groundstrokes and breaking her serve to lead 2-1.
But Radwanska, a top world junior last year playing in just her sixth Grand Slam, event refused to be cowed and she broke back immediately to level at 2-2.
In the blustery conditions Sharapova started to wobble on her serve and Radwanska broke again to lead 5-3.
Sharapova broke back immediately, but once again she struggled on her serve and a double fault gave the Pole set point which she converted with a crisp backhand won the line.
Radwanska took a 1-0 lead in the second set but Sharapova promptly reeled off eight games in a row to stand 2-0 up in the third.
It looked like she was back in command, but another sloppy service game allowed the teenager to claw her way back into the game.
She levelled at 2-2 and then stunned Sharapova and the crowd by breaking again thanks to an 11th double fault from the Russian.
The defending champion was on the ropes and Radwanska provided the coup de grace by converting her fourth break point for a 5-2 lead thanks to a Sharapova forehand drive that died at the bottom of the net.
The Pole then served out confidently, a netcord going against Sharapova on match point.
"It wasn't nice losing eight games in a row, but I had nothing to lose by hitting every ball and I did it," Radwanska said.
The 30th seed will play either Shahar Peer of Israel or Nicole Vaidisova of the Czech Republic for a place in the quarter-finals.
