The aftershocks, on the day after James Scott Connors exited Wimbledon, were still rocking the grounds today. But they were all minor.

On a hot, gorgeous summer day with no sign of the infamous Wimbledon rains anywhere in sight, the top half of the men's draw began to look more and more like an open avenue for Ivan Lendl or Tim Mayotte to reach the final. And on the women's side, there were several mini-upsets, the most notable coming when Nathalie Herreman, a 20-year-old Frenchwoman, beat sixth-seeded Kathy Rinaldi, 7-6 (7-5), 6-4.

But because most people still expect a Martina Navratilova-Chris Evert Lloyd final, it is the men's draw that is receiving most of the attention this week.

And with good reason. By the time this day was over, only three of the eight seeds in the top half of the draw were left. Connors and Kevin Curren didn't make it past the first round. Today, Anders Jarryd (No. 8), Martin Jaite (No. 14) and Johan Kriek (No. 16) didn't make it past the second.

That left Lendl, an easy 6-3, 6-2, 6-2 winner this afternoon over Marcel Freeman, and Mayotte, who beat Jonathan Canter, 7-5, 6-4, 7-6 (7-5), looking at a quarterfinal match against one another next week, with only one seed still alive as a possible semifinal opponent for the winner.

"I don't worry about things like that," Lendl said.

"If you had asked me before the tournament, I would have picked Connors to win. But I guess that was wrong."

Indeed. Today, the man who beat Connors, Robert Seguso, advanced to the third round with a 6-2, 3-6, 6-3, 6-4 victory over Brian Teacher.

The only seed still playing in what was once the Connors-Curren quarter is Joakim Nystrom, a man who doesn't like grass but has nevertheless struggled through two rounds.

Today, he beat veteran Wojtek Fibak in four sets after he got past the ever-dangerous Kelly Evernden in a five-set first-round match.

Seguso may well be the player waiting for the Mayotte-Lendl winner in the semifinals. He is playing the best tennis of his life and played a solid match in the late afternoon today, less than 24 hours after the biggest win of his life, something that isn't easy to do.

"I was a little bit concerned about that last night because I didn't sleep very well last night," Seguso said. "I felt a little sore this morning, and I really would have liked a day off. But I was glad I played as well as I did."

Seguso was amused to learn that by winning he had "lived up to his responsibility," as Connors put it after Seguso beat him.

"Did he really say that?" Seguso asked. "You mean because I beat him I have some kind of responsibility? I can't believe he said that. He hasn't exactly torn up the circuit the last couple of years."

Seguso has never torn up much of anything as a singles player. He and Ken Flach, a doubles partnership ranked No. 2 in the world, have been known strictly as Flach and Seguso in the tennis sphere.

"I think it's hard for people to think of us as anything other than Flach and Seguso," Seguso said with a laugh.

"Sometimes when I win a couple rounds in singles people kid me and say, 'Oh, are you playing singles this week?' If we play each other in singles it might be confusing, since we'll probably wear the same clothes."

They could meet in singles this week, since Flach, who got into the tournament as a qualifier, today upset Jaite, 6-4, 6-3, 6-4, to reach the third round. The other seeds to lose were Jarryd, a 3-6, 6-4, 7-6 (7-2), 6-2 victim of South African Eddie Edwards, and Kriek, who lost a serve-and-volley duel to John Sadri, 2-6, 6-3, 7-6 (7-3), 6-3.

All of this means that Lendl is unlikely to face a truly difficult match until the quarterfinals. As in the French Open, where the draw just seemed to open up before him, things seem to be falling in his favor here.

Everyone keeps talking about what an open tournament this is, and Lendl keeps winning easily. His record dating back to the 1985 U.S. Open is 75-3, yet people still wonder if he has a chance to win this tournament.

"All I'm doing is playing the matches as they come, practicing and then playing the next match," Lendl said. "So far, I'm very happy with the way things have gone."

While Mats Wilander, Boris Becker, Stefan Edberg, Henri Leconte and Paul Annacone go at one another in the lower half of the draw, Lendl could face only one truly tough match on his way to the final.

The best match of the day -- and the biggest upset -- took place at dusk on Centre Court.

In doubles, twins Tom and Tim Gullikson, who say this will be their last summer on the tennis circuit, gave themselves one more memory by coming from two sets down to upset the No. 1-seeded team of Jarryd and Edberg. The Gulliksons, who are almost impossible to tell apart, won, 6-7 (7-5), 4-6, 6-1, 6-4, 6-4.

They will be 35 in September and this victory was a terrific going-away present for two of the best-liked players on the tour.

Barbara Potter of Woodbury, Conn., the 13th women's seed, withdrew today because of a back injury.

Potter, a Wimbledon quarterfinalist last year, was scheduled to play a first-round match against Amanda Brown of Britain, but never took the court. Her place in the draw went to Ronni Reis of Miami.

Potter, a 24-year-old left-hander, injured her back during a practice session before last week's tournament in Eastbourne, England. She played anyway, losing to Betsy Nagelsen, but withdrew from the doubles.
