vijay Amritraj, Bill Scanlon and Eddie Dibbs won their second round matches in the $200,000 World Championship Tennis Invitational tonight at the Wicomico Youth and Civic Center.

Amritraj camb back to take a second-set tie breaker, 11-9, and went on to defeat Brian Teacher, 3-6, 7-6, 6-1.

Teacher appeared to tire late in the middle set and suffered three service breaks in the final set as Amritraj began to play the aggressive game that got him into the finals against Bjorn Borg here last year.

Teacher had match point twice in the tie breaker and watched Amritraj come back from an early 3-0 deficit.

Amritraj totally frustrated the 6-foot-3 Teacher in the final set. Teacher said after he lost the first service of the last set he suffered "somewhat of a letdown."

"It's very mental," said Amritraj. "That's what happened to Brian. He must have been thinking that he was serving for the match at 5-4 still. A good example of that is Borg and (John) McEnroe at Wimbledon."

The last time Amritraj and Teacher met was in September at the U.S. Open in New York. Teacher won that match in four sets.

In the second match of the night, Scanlon (who replaced Eliot Teltscher after he was injured in Tuesday's match with Teacher) defeated Harold Solomon, 6-2, 6-4.

Scanlon broke service three times in the second set and led, 5-3. Scanlon had the serve going into the ninth game of the set but failed to dispose of Solomon because of three double faults. The 5-foot-10 Texan, however, broke serve in the tenth game to win the match.

Dibbs defeated Manuel Orantes, 6-2, 6-4, in the final match last night.

Dibbs was down, 3-1, in the second set but rallied back by breaking service twice.

It was the sixth victory in the 15 meetings between these two dating back to 1971.
