MELBOURNE, JAN. 20 (WEDNESDAY) -- Two-time defending champion Mats Wilander scored a straight-sets victory over fellow Swede Anders Jarryd tonight to reach the semifinals of the Australian Open tennis championships.
Wilander, the No. 3 seed, defeated the sixth-seeded Jarryd, 7-6 (7-2), 6-2, 6-3, in a 2-hour 41-minute battle of wills.
He earned a meeting with either defending champion Stefan Edberg of Sweden or Andrei Chesnokov of the Soviet Union, the last remaining nonseeded player in the tournament.
The other men's semifinal will be between top-seeded Ivan Lendl and Wimbledon champion Pat Cash. Neither has lost a set in the tournament.
The men's semifinals are scheduled for Friday.
Wilander, 23, a model of consistency in swirling winds, won the Australian Open title in 1983 and 1984. He is seeking the fifth Grand Slam title of his career, having also won the French Open twice.
Jarryd provided stiff competition in the first set, which lasted 1 hour 20 minutes. Wilander staved off three set points in the 10th game.
After that, Jarryd's base-line game declined and Wilander was able to outlast him in a number of duels from the back court.
The women's semifinals, scheduled for Thursday, will pit Martina Navratilova against Chris Evert for the 76th time in their long careers, and top-seeded Steffi Graf against fellow West German Claudia Kohde-Kilsch.
Navratilova holds a 40-35 edge in the long rivalry with Evert.
Evert reached the semifinals Tuesday with another easy victory, this time a 6-3, 6-1 romp over 19-year-old West German Claudia Porwik, while Navratilova had a somewhat tougher time, overcoming a brief second-set setback to defeat sixth-seeded Helena Sukova of Czechoslovakia, 6-4, 7-6.
Navratilova, who previously won Australian titles in 1981, 1983 and 1985, was pleased with her effort.
"That was a solid performance all the way," Navratilova said. "I'm playing with good intensity, concentrating well and moving well."
Graf enhanced her already fearsome reputation when she routed defending champion Hana Mandlikova of Czechoslovakia, 6-2, 6-2, Tuesday.
"There is nobody who hits the ball as hard as she does -- that's definite," Mandlikova said of Graf.
