NEW YORK (AP) - Cambodian-born Patricia Hy, 27, defeated Olympic gold medalist

Jennifer Capriati Sept. 4 in the third round of the U.S. Open.

Capriati swatted balls into the net almost as often as Hy, a resident of Toronto,

put away winners with deep groundstrokes and soft touch volleys in a 7-5, 6-4 victory

in the third round.

Capriati, 30 pounds lighter than last year, lacked the energy and strength to chase

down Hy's shots around the perimeter of the court.

Capriati, ranked No. 6, had just come off a victory in a tournament in San Diego

the week before and had every expectation of reaching the finals again.

But she seemed at times like a spectator on the court against Hy, No. 36, who pressed

the action. Hy had more unforced errors, 40 to 30, but nearly twice as many winners,

21 to 11.

"It's taking a little while to sink in I lost," Capriati said.

Hy broke Capriati three times in the second set, the last time to make it 5-4 with

a fine forehand drop volley that Capriati couldn't touch. She held to close out the

match 40-15 with another unreachable backhand drop volley cross court.

"She seemed to have a little problem returning my serve," Hy said. "I'm

not sure if it was she was not moving well. She usually pounds the return."

Hy had lost to Capriati in straight sets in each of three previous matches, including

in the Open the previous two years.

"I've been playing more aggressively," Hy said. "I was able to keep

her on her toes in the match. She usually runs me around on the court."
