Ivan Lendl finished off Boris Becker with two passing shots in a final-set tiebreaker yesterday to win the Seiko Super tournament in Tokyo.

Lendl won, 4-6, 6-3, 7-6 (7-5), in a match delayed an hour while police conducted a search after a telephone bomb threat. None was found.

"It happens sometimes," Becker said. "It did not affect my game. At the end, it's one point and it depends a bit on luck. I know I am on the right track the way I'm playing. It's almost the best I've played in a long time."

Lendl, who earned $122,700 and defeated No. 1 Stefan Edberg in the semifinals, kept his mind on the business at hand.

"This is the first time in about 10 years that I have beaten the top two players in the world back to back," he said. Lendl has held the No. 1 ranking most of the time since 1985.

Lendl started erratically, hitting long or wide, and was broken in the third game after two deuces. Becker broke again in the fifth game and Lendl only narrowed the first set's losing margin by breaking back in the eighth game.

At 5-5 and 40-0 in the third set, Becker let Lendl back into the game for three deuces. The tiebreaker also went to 5-5 before Lendl ended it with a forehand passing shot and then a backhand pass.

Jakob Hlasek and Guy Forget beat Americans Scott Davis and David Pate, 7-6 (7-5), 7-5, in the doubles.

European Indoor: In Zurich, top-seeded Steffi Graf needed just 74 minutes to overpower second-seeded Gabriela Sabatini, 6-3, 6-2, to win the event for the fourth time, gaining a measure of revenge over the No. 4 Sabatini, who defeated her for the U.S. Open title five weeks ago.

"I planned to play aggressively from the start and it succeeded surprisingly well," said Graf, 19-4 against Sabatini.

Sabatini, playing less than 24 hours after a grueling semifinal against Czechoslovakia's Jana Novotna, got off to a slow start and never recovered after twice losing serve in the second set to fall behind, 3-1.

Berlin Open: Sixth-seeded Ronald Agenor of Haiti claimed the title with a 4-6, 6-4, 7-6 (10-8) triumph over eighth-seeded Alexander Volkov of the Soviet Union.
