NEW YORK (AP) -- Laura Robson ran into a camera crew when she stepped outside her hotel before heading to the U.S. Open on Sunday.
''I got really excited because I thought they were waiting for someone who was actually famous,'' she said.
Turns out, that someone was her.
Though her run at Flushing Meadows came to a close with a 6-4, 6-4 fourth-round loss to defending champion Sam Stosur, the 18-year-old Robson has certainly emerged as a player to watch in Britain. She knocked off two former Grand Slam champions and became the first woman from her country to get this far in a Grand Slam since Jo Durie at the 1991 U.S. Open.
''I can definitely take the fact that, you know, I'm up there with the top girls in terms of level,'' Robson said. ''I had two really, really great wins and a tough one today.''
Seventh-seeded Stosur moves on to play top-seeded Victoria Azarenka, who defeated Anna Tatshvili 6-2, 6-2.
In another fourth-round match, No. 11 Marion Bartoli defeated No. 5 Petra Kvitova 1-6, 6-2, 6-0. Bartoli will play the winner of Sunday's late match between No. 3 Maria Sharapova and No. 19 Nadia Petrova.
Robson's loss to Stosur came four days after she defeated Kim Clijsters to end the four-time Grand Slam champion's career. Robson followed that up with a victory over 2011 French Open champion Li Na.
Stosur was the latest major champion on Robson's list and the teenager put up a good fight, saving eight match points after falling behind 5-2 in the second set. In the end, 41 unforced errors did her in.
''Sam is someone who sort of makes you feel like you're playing bad because she hits it with so much spin,'' Robson said. ''But it's been a good tournament for me.''
And a good summer, as well. Robson teamed with Andy Murray to win the silver medal in mixed doubles at the London Olympics. She was ranked 111th in singles before Wimbledon and is projected to rise to around No. 75 after the U.S. Open.
''I said the other day that I felt like the level has always been there,'' Robson said. ''It's just been putting it into the matches and managing to keep it for the whole match.''
Stosur still hasn't dropped a set at the U.S. Open in what has, so far, been a fairly low-profile tournament for the defending champion.
She said it did get a little frustrating letting all those match points slip away. Robson saved five of them by hitting shots Stosur couldn't get back.
''Sometimes, it takes a few of them to get through,'' Stosur said. ''Again, if you're not doing the wrong things on those points, you can't get too down on yourself.''
While Stosur plays on, Robson will head to stops on the tour in Asia, trying to gain more experience and nudge herself up the rankings a little. She's still got a little more time in New York, though, and plans to do some shopping.
Asked if she was looking for anything specific on the shelves, she sounded like a seasoned veteran.
''I find if you go out with an open mind,'' Robson said, ''you find a lot more.''
