Ivan Lendl and Jimmy Connors, the two top-seeded players, each scored straight-set victories Saturday to advance to the final of the $150,000 Executone Hamlet Challenge Cup at Jericho, N.Y.
They will meet today for the $35,000 first prize in a final tuneup for the U.S. Open, which begins Tuesday.
Lendl, the defending champion who is seeded No. 1, defeated unseeded Paul Annacone of Bridgehampton, N.Y., 6-3, 7-6, fighting off three straight set points before winning the second-set tiebreaker.
Connors, seeded second, defeated fifth-seeded Miloslav Mecir of Czechoslovakia, 6-2, 7-5.
Boris Becker of West Germany came back from a two-hour rain delay and served three aces to defeat Joakim Nystrom of Sweden, 6-4, 7-5, in the semifinals of the Assn. of Tennis Professionals tournament at Mason, Ohio.
In today's final, Becker will face top-seeded Mats Wilander of Sweden, who defeated Tim Wilkison of Asheville, N.C., 6-2, 6-1.
Becker's victory was highlighted by a somersault by the 17-year-old Wimbledon champion. Trailing 4-5 in the second set and with the score 15-15 in the 10th game, Becker did the somersault as he came up to hit the ball and win the point. He ended up winning the game to tie the set, 5-5.
