Top-seeded Pam Shriver outlasted Jana Novotna, 7-6 (8-6), 7-6 (7-4), to win the $162,000 Women's Tennis Classic in Brisbane's 90-degree temperatures that caused one spectator to faint during the match.

Shriver, of Lutherville, Md., the world's fourth-ranked player, needed almost two hours to capture the grass-court title in a warm-up for the Australian Open later this month.

Novotna, a 19-year-old from Czechoslovakia, used a fierce serve and an aggressive all-court game to extend both sets to tie breakers. Shriver, who had breezed past early-round opponents, saved four set points in a tense first-set tie breaker before clinching it, 8-6.

Shriver then broke Novotna twice when she was serving for the second set.

Shriver later teamed with Betsy Nagelsen to win the doubles final against West German Claudia Khode-Kilsch and Czechoslovak Helena Sukova, 2-6, 7-5, 6-2 . . .

In Wellington, New Zealand, sixth-seeded Ramesh Krishnan of India beat No. 4 Andrei Chesnokov of the Soviet Union, 6-7 (9-7), 6-0, 6-4, 6-3, to win the New Zealand Open. Krishnan needed 2 hours 45 minutes to win the sixth title of his career.
