TENNIS ROUNDUP : Ailing Sampras Drops Out, Krickstein Is Knocked Out

Top-seeded Pete Sampras withdrew because of injury and fifth-seeded Aaron Krickstein was upset by Peter Lundgren of Sweden, 7-5, 6-4, Thursday in an indoor tennis tournament at Wembley, England, leaving only three seeded players entering the quarterfinals.

Sampras pulled out before his second-round match against Christian Bergstrom because of painful shin splints that threaten to keep him out of next week’s ATP Finals.

“If I played today there could be a chance of more serious injury,” he said. “My health comes before anything. I’m 19 years old and I don’t want to be retired by the time I’m 23.”

Krickstein lost his serve twice near the end of the first set and two more times at the beginning of the second set as Lundgren won eight out of 10 games in that stretch.

In other matches, second-seeded Goran Ivanisevic of Yugoslavia defeated Niclas Kulti, 7-6 (10-8), 6-4, and third-seeded Michael Chang beat Jeremy Bates, 6-3, 6-3.

Second-seeded Emilio Sanchez of Spain beat Veli Paloheimo of Finland, 2-6, 7-5, 6-2, in the Kremlin Cup at Moscow.

Also advancing to the quarterfinals were Petr Korda of Czechoslovakia, who defeated Jan Gunnarsson of Sweden, 1-6, 7-6, 6-2; Sergio Casal of Spain, who defeated Marc Rosset of Switzerland, 6-4, 6-3, and Anders Jarryd of Sweden, who beat David Wheaton, 6-3, 7-5.

Mats Wilander of Sweden routed Andrew Sznajder of Canada, 6-1, 6-0, in the quarterfinals of the Citibank tournament, played in 100-degree temperatures at Itaparica, Brazil.

In other matches, Mark Koevermans of the Netherlands defeated Maurice Ruah of Venezuela, 7-6 (7-4), 6-3; Thomas Carbonell of Spain beat Cassio Motta of Brazil, 6-3, 7-5, and Marcelo Filippini of Uruguay downed Nuno Marques of Portugal, 6-3, 3-6, 7-6 (7-4).

Nicole Provis needed only 67 minutes to upset sixth-seeded Claudia Porwik, 6-1, 6-4, and reach the quarterfinals of the Jell-O tournament at Indianapolis.
