Martina Navratilova is a poor role model for aspiring professional tennis players because she is homosexual, former Grand Slam winner Margaret Court said.

Court, 47, a winner of 25 Grand Slam titles, including three at Wimbledon, said in interviews yesterday in Perth, Australia, that Navratilova's admitted homosexuality is a bad example for younger players.

"She is a great player, but I'd like to see somebody at the top to whom the younger players can look up to," said Court. "It is very sad for children to be exposed to it. Martina is a nice person. Her life has just gone astray." . . .

Peter Johnson, who represents Navratilova for International Management Group in Cleveland, said she would have no comment. . . .
