NEW YORK, SEPT. 6 -- It has been a hectic three days for Mark Woodforde. The 21-year-old Australian, who got into the men's draw here by qualifying, upset Tim Mayotte in the second round Friday, winning a fifth-set tie breaker.

That night he called his parents in Australia, waking them at 6 a.m. to see if they had heard about his victory. They had seen highlights on television. Saturday he was back to play (and win) a mixed doubles match.

Today, he pounded Milan Srejber in straight sets to reach the round of 16, grabbed something to eat and then went off to play another mixed doubles match. He was also planning to practice with Steffi Graf, who likes to practice with Woodforde before she plays a left-hander. Monday, she plays lefty Sylvia Hanika.

"It's been hectic, but a lot of fun," said Woodforde, a freckle-faced redhead who will be 22 this month. "I'm trying not to get too excited because I'm afraid if I do I'll go out in my next match and just get blown away. I wouldn't want that to happen."

Woodforde's next will play fifth-seeded Miloslav Mecir. His giddy run should end there. But his ranking should jump after the tournament from 134th into the top 100. That will mean getting straight into the draw of most Grand Prix tournaments. All in all, not a bad week's work.

There will be no night matches Monday because the New York Mets are having a fireworks display after their game with the Philadelphia Phillies. That means three straight men's matches on the Stadium Court and a lot of women's matches relegated to outside courts since all eight round of 16 matches must be played . . .

The draw in the bottom half has really opened up for Stefan Edberg. His next opponent will be either Jaime Yzaga or Jonas B. Svensson and in the quarterfinals he will face Andrei Chesnokov or Ramesh Krishnan. Not a seeded player in sight, although Krishnan did take him five sets here last year . . .

Edberg has a reputation for having a dry, sly sense of humor. Today, he was asked to tell a favorite joke.

"You can't print it," he said, smiling. Then he told the joke. He was right. It wasn't dirty, but it can't be printed. But it was funny. And he made telling it sound easy . . .

Barry MacKay of CBS failed to ask John McEnroe about his run-in with a fan or his arguing with chair umpire Rich Kaufman after McEnroe's second-round match Thursday night. MacKay is the director of a tournament in San Francisco that McEnroe annually plays in.
