Sometimes success can be a curse. Jaime Yzaga came to the U.S. Open with high hopes. He was the No. 1 seed in the boys 18-and-under singles. But he made a mistake: He entered the men's singles as a qualifier, hoping only to make the main draw.

He made the main draw, winning three qualifying matches. But that wasn't the end. Yzaga proceeded to beat Jakob Hlasek, Dan Cassidy and David Pate and reached tonight's round of 16, facing Ivan Lendl on the stadium court.

All well and good except that Yzaga had a boys match today. Since he could not play two singles matches in the same day -- much less a three-of-five-set match against the No. 2 player in the world -- he asked for a day's delay in his boys match.

Sorry, said the U.S. Tennis Association, you have to default.

"It was ridiculous, that schedule," Yzaga said after performing admirably in a four-set loss to Lendl. "This guy, the referee (Bob Howe) schedules me to play in the afternoon when I'm playing the No. 2 player in the world at night and he thinks it's a great schedule."

Yzaga was particularly disappointed because his default ruins his chances to be the No. 1 junior in the world for this year.

Players here constantly complain about the movement of fans in and out of the stadium and the grandstand. Crowd control here is about one-tenth of what it is at the French Open or Wimbledon. John McEnroe thinks there is a reason.

"The ushers here aren't really tennis fans. They're more baseball or football fans," he said. "They don't understand that they have to just get people in and out and they're all trying to give people better seats to make an extra buck.

"I don't have any problem with somebody trying to make an extra buck but it does make it hard to play and hard to concentrate. I think if they wanted to correct the problem, they could. That's not the whole problem, but it's part of it."
