Top-seeded Boris Becker was down by two games before winning six of seven games in the final set to beat No. 4 Jay Berger, 6-4, 6-3, yesterday in the semifinals of the U.S. Hardcourt Championships in Indianapolis.

Becker advanced to today's final in his only hardcourt event before the U.S. Open begins Aug. 27.

The world's third-ranked player will face unseeded Peter Lundgren, who scored his second straight upset with a 6-4, 6-4 victory over No. 14 Richey Reneberg.

Berger held serve to open the second set. He took advantage of a loose service game by Becker to win four straight points and lead, 2-0. The West German, the 1988 champion of this event, took Berger to deuce three times in the third game before the American netted a forehand that pulled Becker within 1-2.

"All of a sudden I felt good again and everything seemed to work well for me," said Becker, who won 13 of the next 14 points.

The American has never beaten Becker in five meetings, and he said he knew immediately that it wouldn't happen here. "The heat was getting to me. When we warmed up, we knew whatever happened on the court was not going to be fun. It wasn't," said Berger, ranked 13th in the world and a finalist in Indianapolis last year.

Virginia Slims of Los Angeles: Top-seeded Martina Navratilova suffered a second-set collapse but came back to defeat No. 4 seed Zina Garrison, 6-0, 6-7, 6-4, in the semifinals.

Navratilova advances to the final of the $350,000 event where she will face Monica Seles, a 6-1, 6-0 winner over Mary Joe Fernandez.

The Navratilova-Garrison semifinal was a rematch of the 1990 Wimbledon final, which Navratilova won, 6-4, 6-1, for a record ninth title at the Grand Slam event.

Navratilova had a harder time with Garrison this time, however. After breezing through the first set and losing only eight points, Navratilova faltered. Up by 5-4 in the second set, Navratilova was serving for the match but could not hold her serve.

Garrison held on to force the tiebreaker and won it, 7-2, to take the set.

After that, however, Garrison's serve troubled her. She lost the final game at love after two double faults.

"It was much closer than it should have been," Navratilova said of the 1-hour 42-minute match.

Volvo International: Derrick Rostagno switched rackets and found his game, keeping Andrei Chesnokov off balance with pinpoint drop shots and cross-court passes to reach the final in New Haven, Conn.

The victory capped a week of upsets in which all but one of the 16 seeds lost before the semifinals. Rostagno beat the fifth-seeded Chesnokov, 7-6 (7-4), 6-3.

Rostagno, ranked 79th, faces Todd Woodbridge, a 1-6, 6-4, 6-4, 6-3 winner over fellow Australian Mark Woodforde.
