Zina Garrison thinks Jeri Ingram is a lot like her. That doesn't mean that when the two meet in the second round of the $300,000 Virginia Slims of Washington at George Mason's Patriot Center, she isn't going to try to knock Ingram's block off.

Garrison advanced with a 6-2, 5-0 (ret.) victory over Isabelle Demongeot, on a day when the top two seeds advanced to the second round easily. Top-seeded Martina Navratilova took just 57 minutes to beat Judith Wiesner, 6-2, 6-3, and second-seeded Pam Shriver beat Nicole Provis, 6-0, 6-4.

Garrison, the tournament's sixth seed, had as little trouble with Demongeot as the top seeds had with their opponents. Her serve and volley game was complemented with Demongeot's inability on first serves (21 percent in the first set, 9 in the second, 15.7 for the match).

At 5-0, 30-40 on Demongeot's serve, she pulled up, and with tears in her eyes, walked off the court, clutching her stomach.

"It's a very sad ending," Garrison said. "She just couldn't seem to catch her breath or anything. It was match point . . . I'm not sure what happened, but it had to feel really bad for her to quit like that."

Garrison will face Ingram, the 17-year-old Springbrook High senior and a wild-card entry in the 32-woman draw, on Thursday. She's hit with Ingram a couple of times, but said facing the hometown favorite wouldn't bother her.

"It's going to be just another match," Garrison said. "She's going to be very hungry, but I feel that I've been playing well {she made the semifinals at Dallas and Oakland} and I'm going to go out there and do the things that I know I do best."

Garrison said she knows Ingram as one of the up-and-coming young black tennis players. Ingram's demeanor is familiar to Garrison.

"Very fiery," Garrison said. "I saw her play doubles last year, and the first ball she hit straight at {Hana} Mandlikova. And that's something that, in my young years, I would have done. She reminds me a lot of myself, because she doesn't seem to be afraid of anything."

On the evening card, Shriver took the first set of her match in 21 minutes, and got off to a 5-1 lead in the second set. But Provis began nailing forehand and backhand winners, and won three straight games to get back to 5-4.

She was at 30-30 when Shriver delivered one of her eight aces, then did the same to end the match.

After losing the first game off her serve for a 1-1 first-set tie, Navratilova dropped just one point in her next three service games.

In the second, Navratilova broke in the fifth and seventh games for a 5-2 lead. But Wiesner broke back for 5-3, then had four deuces on her serve before making two unforced errors.

In matches yesterday afternoon, Robin White was leading Ann Henricksson, 6-2, 2-0 in the second set, when Henricksson retired with a leg injury. In the next match, a stomach ailment forced Eva Pfaff to withdraw before play began.

Peanut Louie Harper, the tournament's lucky loser, replaced Pfaff in the draw. Phelps beat her in straight sets, 6-3, 6-2. In the afternoon's other singles match, Gigi Fernandez rallied to beat Heather Ludloff, 6-7 (7-4), 6-4, 7-5.

In doubles, Gabriela Sabatini and Helena Sukova, the second-ranked team, didn't drop a game in routing Harper and Ludloff, 6-0, 6-0.

Slims Notes:

Sparse crowds attended the afternoon sessions for the second straight day. The evening session drew 4,700 in the near 10,000-seat Patriot Center. Many were late for the Shriver-Provis match because of the earlier starting time of 6:30 . . . Today's evening matches will also begin at 6:30, not 7 p.m.
