WIMBLEDON, England (AP) -- Defending champion and to seed Stefan Edberg used a couple of short streaks to bounce John McEnroe out of Wimbledon today.
Edberg beat McEnroe, a three-time champion, 7-6 (7-4), 6-1, 6-4, and moved into the quarterfinals.
Top women's seed Steffi Graf and fifth seed Mary Joe Fernandez rolled to easy victories and advanced to a semifinal meeting.
Graf defeated seventh seed Zina Garrison 6-1, 6-3, gaining revenge for her loss to Garrison in the 1990 semifinals. Fernandez won 6-2, 7-5 over fourth seed Arantxa Sanchez Vicario.
Edberg ran off 15 straight points midway through the second set and then won 16 of 20 points in a third-set spurt.
Edberg won the tie-breaker to end a first set that went entirely on serve. The 16th-seeded McEnroe seemed to sag after the tie-breaker.
"He outplayed me. When it really came down to it, he just played a little better than I did," said McEnroe, who complained about a few line calls but avoided any major verbal explosions.
"His game is suited to grass, it's a natural. Anyone that volleys that well is going to be good on grass. I would have preferred to play a lot of other guys."
Also advancing to the quarterfinals was French Open champion Jim Courier, who defeated 14th seed Karel Novacek 6-3, 6-4, 6-2.
His next opponent will be sixth seed Michael Stich, who rallied to win the final three games for a 4-6, 6-3, 7-5, 1-6, 7-5 victory over Alexander Volkov. Courier defeated Stich in the semifinals of the French Open.
The fourth-seeded Courier, whose best previous Wimbledon performance was reaching the third round last year, now has lost only 13 games in his last two victories.
"It's kind of unexpected to me, because I'm not a natural grass-court player," Courier said. "I'm pleasantly surprised to be in the quarterfinals."
Three other Americans -- Andre Agassi, David Wheaton and Tim Mayotte -- won matches yesterday, joining Derrick Rostagno in the fourth round.
Agassi, Wheaton and Mayotte have taken Wimbledon by storm, rolling through the tournament with hardly a care in the world.
"The excitement of Wimbledon speaks for itself. Just being here at Wimbledon and having such a warm response is something more than anyone really deserves," said Agassi, a crowd favorite who used a day off Sunday to tour the town.
"Yesterday I just went sightseeing all day and saw a bunch of things that I don't remember the names to. But I enjoyed them."
Agassi, who defeated Dutch teen-ager Richard Krajicek 7-6, 6-3, 7-6, stuck with his traditional all-white outfit but added designer sunglasses for a few games yesterday.
Wheaton, showing off his stars and stripes bandana on Centre Court, wiped out third seed Ivan Lendl. The Minnesotan boomed 16 aces in a 6-3, 3-6, 7-6, 6-3 defeat of the two-time Wimbledon finalist.
But Wheaton was not yet ready to party.
"You can do that if you beat him in the finals of the tournament, but when you're in the middle of the tournament you're still trying to win the whole thing," he said. "It's not just one match. It's not like a boxing match where you knock the guy out and go celebrate."
Mayotte, who smiled through the last three sets of his first-round comeback victory over Michael Chang and then blew kisses to his girlfriend, laughed his way to another victory Monday.
The unseeded Mayotte, playing in his first tournament since April, defeated Patrik Kuhnen 3-6, 6-2, 7-6, 6-4.
The Americans said they draw inspiration from each other. Wheaton said he was spurred on by Courier's recent victory in the French Open.
"It kind of gave me the feeling that I could win a Grand Slam also," said Wheaton, a grass-court specialist who also reached the fourth round at Wimbledon last year. "I guess it did in a way fortify me a little bit."
Four Americans also reached the women's quarterfinals, led by defending champion Martina Navratilova.
Navratilova, playing in her record 112th Wimbledon singles match, won 6-1, 6-3 over Catarina Lindqvist to set up a clash with ninth-seeded Jennifer Capriati. The 15-year-old Floridian rallied to defeat Brenda Schultz of the Netherlands in three sets.
Mary Joe Fernandez and Zina Garrison also advanced to the quarterfinals. Garrison's victory set up a quarterfinal battle against top seed Steffi Graf, who lost to Garrison in the 1990 Wimbledon semifinals.
