Other leading participants are No. 3 ranked and 1988 Wimbledon Champion Stefan Edberg of Sweden, No. 5 ranked and 1988 Wimbledon finalist Boris Becker of West Germany, and 1988 Australian Open finalist Pat Cash

The organizers said they have not invited U.S. Open champion Mat Wilander of Sweden, the world's top ranked player, because of his tight schedule. Wilander ended Lendl's three-year reign with a dramatic five-set victory Sept. 11 in the longest final in U.S. Open history.

Edberg is the defending champion, beating Lendl 6-7, 6-4, 6-4 last year.
