Second-seeded Boris Becker was tired. He was out of top physical condition. But, coming off a first-round bye, he hit enough good shots enough times for a second-round victory last night in the Sovran Bank/D.C. National Tennis Classic at Rock Creek Tennis Center.

Becker defeated Richard Matuszewski, 6-4, 7-5, before a capacity crowd of 5,500 on the stadium court, despite feeling the effects of his marathon weekend matches in the Davis Cup relegation round against the United States in Hartford, Conn.

"I wasn't feeling well because of the matches I had and I wasn't in shape," Becker said. "I was playing so many hours. You don't feel it Sunday or Monday, but you start feeling it Tuesday when you want to hit."

Led by top seed Ivan Lendl, also making his first appearance in singles with a second-round match and taking it by 7-6 (7-2), 6-3 over Brad Pearce, all the seeded players in action advanced.

Fourth seed Brad Gilbert needed to regroup to defeat Chip Hooper, 6-3, 2-6, 6-1, and No. 5 Johan Kriek prevailed, 7-6 (7-3), 6-4, over Jeff Tarango.

No. 8 Jay Berger beat Jay Lapidus, 6-2, 6-3; No. 12 Todd Witsken topped Brad Drewett, 6-3, 7-6 (7-5); No. 13 Nduka Odizor of Houston had little trouble with Stephane Bonneau of Canada, 7-5, 6-0, and 14th-seeded Jim Pugh ousted Michael Westphal of West Germany, 6-2, 6-4.

Becker broke Matuszewski in the first game and proceeded to take a 3-1 lead. Matuszewski had a break point at 30-40 in the eighth game but Becker hit a crosscourt forehand for a clean winner for deuce.

A Becker double fault gave Matuszewski another break opportunity, and Becker hit a forehand long to tie it at four. Becker quickly broke back, slamming a crosscourt forehand for 0-30 and reaching 0-40 when Matuszewski's half-volley hit the top of the net and fell back in his court. Becker served out for the first set.

"When I was up a break or on serve, he tried much harder," Matuszewski said.

Becker broke Matuszewski again in the first game of set two, then each held serve to get to 5-4, Becker.

Serving for the match, Becker hit a forehand long for 0-30 and netted a forehand from the base line for 0-40. After hitting a clean forehand winner and a crosscourt backhand passing shot for 30-40, Becker hit a backhand out and the set was tied at 5.

Back came Becker, nailing a second-serve return crosscourt for 0-15. Matuszewski netted a forehand for 0-30, but tied at 30 following two Becker errors. Matuszewski half-volleyed at net for 40-30, but barely touched a Becker backhand to the base line.

The two reached deuce three more times before Becker broke for 6-5, on a Matuszewski crosscourt backhand and half volley at the net that both went long.

Becker held serve easily for the match.

"I was expecting him to serve and volley more than he did. I'm sure there's a reason for it. It's fine with me, because I had a better chance of winning," Matuszewski said.

Earlier, Lendl lagged, 4-1, in the first set before winning three consecutive games and eventually forcing a tie breaker.

Pearce held in the ninth game for a 5-4 lead, and Lendl aced to close out game 10. Each held easily to set up the tie breaker.

Lendl went to 3-1 in the tie breaker when Pearce hit an overhead smash out. A Pearce approach went long for 4-1. A Lendl service winner made it 5-1, and Lendl went to 6-2 after Pearce netted a half-volley. Pearce netted a forehand for the final point.

"I think the tie breaker just broke him down mentally," Lendl said. "I just didn't play all that well in the beginning. He played solid. He's not the kind of person who's going to beat himself."

Lendl broke again in the fourth game of set two. At 0-30, he blasted a forehand winner from the back line. He got the game when Pearce volleyed long, for 3-1.

Lendl then held held his serve to take the match.

Pearce said there was no pressure on him, and once Lendl won the tie breaker, Pearce sensed Lendl felt less tight than at the beginning of the match.

"I felt like he relaxed a little more {at the beginning of the second set}," Pearce said.

David Wheaton, 18, the junior player who made the tournament as a wild-card entry, continued into the third round with a three-set win over Jonny Levine, 4-6, 6-3, 6-2.

"I thought it {playing Lendl, his chore today} was kind of far-fetched. Then when I was up 4-1 in the third set, I started to think Lendl," Wheaton said.

In other second-round matches, Blaine Willenborg, who defeated ninth seed Dan Goldie on Monday, beat Christo Steyn, 4-6, 7-6 (7-5), 6-2, and Marty Davis knocked off Bill Scanlon, 6-2, 4-6, 6-2.

Laurie Warder win his second match in less than 24 hours, a 6-4, 6-4 decision over "lucky loser" Craig Miller of Australia. Miller had taken the place of sixth seed Aaron Krickstein, who pulled out Tuesday with an apparent stress fracture of the left tibia.

In doubles, top-seeded Paul Annacone and Christo van Rensburg beat Goldie and Larry Scott, 6-3, 6-2.

Steve Denton and Sammy Giammalva took the fourth-seeded team of Ken Flach and Christo Steyn, 6-7 (10-8), 6-4, 6-1.
