Jamie Hampton and Laura Robson express disappointment over their third-round losses at the U.S. Open. Hampton fell to fellow American Sloane Stephens, 6-1, 6-3, while Robson lost to Li Na, whom she had beaten in New York last year, 6-2, 7-5.

“I’ve had tendencies, shown tendencies to play really bad in big moments,” said the No. 23 seed Hampton. “Kind of sucks. I’m incredibly, incredibly disappointed in the way I played today…[Sloane] ‘s had a lot more experience on the big stage. I think personality-wise she embraces it a little better than I do. With my personality, I tend to shy away from it a little bit.”

Robson, who came into a major seeded for the first time at No. 30, said she wasn’t that pleased with her season overall.

“I would say I set my expectations quite high, so for me it’s still quite disappointing,” the 19-year-old said. “I would love to be more consistent at the smaller tournaments. So that’s what the plan is for Asia. But I think I have a lot to work on, and I think I can improve a lot more. Hopefully in the next few months I won’t still be around 30.”
