MELBOURNE, Australia — Eleventh-seeded Pat Cash of Australia upset top-seeded Ivan Lendl of Czechoslovakia, 7-6, 5-7, 7-6, 6-4, in a four-hour marathon today to advance to the final of the $1.65-million Australian Open tennis championships.
Cash's victory sent him into Sunday's title match against defending champion Stefan Edberg of Sweden, who earlier defeated unseeded Wally Masur of Australia, 6-2, 6-4, 7-6.
The loss meant that Lendl, ranked No. 1 in the world, still has not won a Grand Slam event on grass. Cash, who had never previously beaten Lendl, qualified for the first Grand Slam final of his career.
The victory came at the same Kooyong center court on which Cash helped Australia win the Davis Cup against Sweden last month.
