MELBOURNE, JAN. 12 (TUESDAY) -- Seventh-seeded Henri Leconte conquered near 100-degree heat and Australia's Peter Carter this morning to advance to the second round of the $1.9 million Australian Open.

France's Leconte prevailed, 6-1, 3-6, 6-1, 6-4. "In the second set I couldn't move, it was so hot," he said. "This new surface {a synthetic hard court} gets really hot, particularly under your feet."

Australian Brod Dyke eliminated ninth-seeded Jakob Hlasek of Switzerland, 6-3, 6-3, 6-4, today.

On Monday, opening day of play at the new $60 million National Tennis Center, two seeds fell.

Wendy Wood, daughter of former major league knuckleball pitcher Wilbur Wood, defeated 14th-seeded Dianne Balestrat of Australia, 6-2, 4-6, 8-6, her biggest victory. Frenchman Jerome Potier ousted No. 13 male Paul Annacone, 3-6, 4-6, 6-3, 7-5, 6-4, leaving the United States without a seeded player in what started as a 128-player men's draw.

Top-ranked Ivan Lendl staved off Bryan Roe, 18, of Australia, 6-3, 7-6, 6-2, Monday night. No. 4 seed Pat Cash of Australia topped Austrian left-hander Thomas Muster, 7-5, 6-1, 6-4, and No. 5 Yannick Noah labored past power-server Roger Smith of the Bahamas, 6-7, 5-7, 6-4, 6-2, 16-14. Cash, the Wimbledon champion, was fined $500 for shouting at obscenity at a linesman in the final game.

A number of antiapartheid demonstrators were escorted from the stadium court after shouting insults at Cash and throwing black tennis balls onto the court. Cash played in South Africa late last year.

In women's singles Monday, No. 2 seed Martina Navratilova trounced Elizabeth Minter, 6-3, 6-0, and No. 3 Chris Evert beat fellow American Gretchen Magers, 6-4, 6-0.
