One McEnroe won, one didn't yesterday in Philadelphia at the U.S. Pro Indoor championships.

Fourth-seeded John McEnroe had little trouble with Alexander Mronz, 6-1, 6-2, while MaliVai Washington had little trouble with 16th-seeded Patrick McEnroe, 6-0, 6-3, in second-round matches.

Top-seeded Ivan Lendl outlasted determined Guillaume Raoux, 6-1, 7-5, to reach the third round. In the night's final match, No. 3 Brad Gilbert dispatched Tomas Carbonell of Spain, 6-3, 6-3.

McEnroe, who turns 32 Saturday, missed last month's Australian Open with a bad shoulder, but he said "my shoulder feels great. My body is coming along."

Kevin Curren upset No. 11 Darren Cahill, 6-7 (7-9), 6-3, 7-6 (7-2). Cahill won last week in San Francisco.

Donnay Indoor: In Brussels, Boris Becker, with his recently attained No. 1 ranking on the line this week, beat Alexander Volkov, 6-4, 3-6, 6-3, in an opening-round match.

Becker claimed the top spot for the first time by winning last month's Australian Open. Had he lost yesterday, second-ranked and second-seeded Stefan Edberg would have had a shot at returning to No. 1. Edberg is through to the third round, having beaten Magnus Gustafsson, 6-0, 6-4.

The winner of the tournament earns 180 Association of Tennis Professionals points; Becker's lead over Edberg is 133 points.

Third-seeded Andre Agassi lost his opening match to No. 153 Christian Saceanu, 6-3, 7-6 (9-7). Agassi is coming off a semifinal rout by Brad Gilbert last week in San Francisco.

Seventh-seeded Michael Chang and No. 4 Guy Forget won second-round matches. Mats Wilander, ranked 80th, won his first-round match against Omar Camporese, 6-4, 7-6 (7-5).

Virginia Slims of Chicago: Top-seeded and 10-time champion Martina Navratilova and No. 4 Jennifer Capriati eased into the quarterfinals. Navratilova beat former doubles partner Pam Shriver for the 26th straight time, 7-6 (7-3), 6-1, and Capriati recovered from 4-1 in the first set vs. Tami Whitlinger, 6-4, 6-1.

Navratilova said she broke 100 mph on her serves for the first time in her career.

Helen Kelesi rallied to upset No. 3 Jana Novotna, 2-6, 7-6 (7-5), 7-6 (7-1), in 2 hours 40 minutes.
