The hands of Sean O'Neill are carefully looked after by his personal table tennis coach.

O'Neill is one of more than 150 Washington, D.C., area athletes at the National Sports Festival, and so far he is perhaps the most successful. In Saturday's team competition, the 17-year-old from Vienna, Va., went unbeaten in eight matches to help the East team to the gold medal. In today's individual round-robin tournament, he won three matches without losing a game.

O'Neill, who plans to attend George Washington in the fall, does not have just any ordinary coach. Chartchai Teekaveerakit, an 18-year-old exchange student who is living with O'Neill's family, is the men's champion of Thailand.

"I think I'm a heavy favorite," he said. "I'm not afraid of anybody here. They're more afraid of me. I'd have to say I'd be disappointed if I lose."

Eleni Rossides of Washington, D.C., top-seeded in the women's tennis tournament, reached the semifinals, 6-4, 6-2, over Jana Garrison of Denham Springs, La.
