Alison Riske of the USA celebrates beating Petra Kvitova at the US Open
American wildcard Alison Riske produced the biggest match of her career to dump former Wimbledon champion Petra Kvitova out of the US Open third round.
The 23-year-old Riske had never won a match at a grand slam heading to Flushing Meadows, but the world No 81 produced a storming effort to beat the seventh seed 6-3 6-0 to make the fourth round in New York.
Czech star Kvitova had spent the previous day in bed with a fever, and did call for the trainer before the final game of the match, but has never enjoyed Flushing Meadows as it is the only major she has failed to reach the semi-finals of.
Kvitova was broken five times by Riske - who once ahead really pushed home her advantage by winning the last eight games of the match to secure the upset victory.
"I've got a new confidence in myself," Riske said in her emotional courtside interview. "I believe that I belong here.
"It was really emotional for me. It's cool because I feel like I'm playing within myself and not doing anything too crazy. It's just really comfortable for me out there."
Kvitova insisted she was not in the best of health - saying she went for every shot trying to keep the rallies short - after making 27 unforced errors and seven double faults.
"My body wouldn't let me fight," Kvitova said. "She moved quite well. She pushed me to the back. That was tough for me."
Second seed Victoria Azarenka almost suffered a shock as she had to come from a set down to progress into the fourth round with victory over Alize Cornet.
The pair played out a ding-dong first set, which Cornet took on a tie-break, before last year's runner-up hit back to claim victory 6-7 (2/7) 6-3 6-2 in a little under two hours and 40 minutes.
Azarenka fought off break points before breaking Cornet to go 4-2 up in the second set, after that provided the shift in momentum needed for her to go on and battle through.
"In the first set, Alize played really well and I made too many mistakes," Azarenka said. "I wasn't patient enough. I had a lot of chances and I didn't convert them.
"The difference in the second and third sets was I played a bit more aggressive and when I got my chances I did convert them."
Azarenka, the two-time Australian Open winner, will now face Ana Ivanovic for a place in the quarter-finals after the Serb also fought back from a set down.
Ivanovic was heading out of the tournament when American Christina McHale served at 5-4 and a set up, but the 13th seed broke serve before claiming the set herself.
From there, the 2008 French Open champion broke again late in the deciding set to seal a 4-6 7-5 6-4 victory in two hours, 26 minutes.
