They are Neale Fraser and Frank Sedgman, Australian tennis players, aged 48 and 53, respectively. Each has a title-laden history that includes a championship at Wimbledon -- Sedgman in 1952 and Fraser in 1960.

Only in the nationalistic sense are they the forefathers of Peter McNamara and Paul McNamee, today's Australian stars who are ranked eighth and 32nd on the ATP computer.

In the global sense, they are the predecessors of Bjorn Borg and John McEnroe -- both were among the best of their time.

Now both men are playing the Grand Masters tour, where membership is based on three qualifications: the player must be 45 or older, must have won a major title and must still be able to play competitively.

Last night, Sedgman and Fraser played each other in a semifinal of the Grand Masters tournament being held in conjunction with the Washington Star International at Rock Creek Stadium.

Sedgman won in 1 hour 50 minutes, 7-6, 1-6, 7-5, and will play Mal Anderson in the final at 7:45 tonight. Anderson defeated Alex Olmedo, 6-2, 6-0, in the other semifinal.

"I have played Neale many, many times in the Grand Masters. Generally, I have had quite an edge on him," said Sedgman, the No. 1 seed, who has won 44 tournaments and more than $330,000 since the Grand Masters began in 1973. No one else has won half as many titles nor half as much money. "But I'll tell you, he hit some shots in that third set that I didn't expect."

Fraser, whose serves were considered the best by a left-hander in the pre-Roscoe Tanner days, broke Sedgman's serve in the ninth game of the final set to take a 5-4 lead. He only had to hold his serve -- something that was considered nearly a certainty in the early 1960s -- to win the match.

Fraser has not won a Grand Masters tournament in his 3 1/2 years on the tour. He won't win this one, either. Sedgman won four straight points in the 10th game to break Fraser's serve to tie the third set, 5-5. Sedgman then held serve in the 11th game before breaking Fraser's serve in the 12th game to win the match.

"I lost my concentration in the second set," said Sedgman, smiling, sweating and ready for another Grand Masters final.
