John McEnroe beat Guillermo Vilas, 7-5, 6-0, to win the $200,000 first prize in the Challenge of Champions in Las Vegas.

McEnroe, who reportedly also got $200,000 just to appear, took only 68 minutes to win the final of the eight-player, round-robin event. He broke Vilas' service six times and served eight aces.

Vilas was playing with less than 12 hours rest after beating Ivan Lendl late Friday night and seemed to tire in the second set.

Later last night, Jimmy Connors, who lost to McEnroe Friday, played Yannick Noah for third-place prize money of $50,000.

Vilas, who also shared in the $775,000 guaranteed appearance money paid to the eight players, got an additional $100,000 in prize money for finishing second.

Each player also received $10,000 for each match won during the exhibition-style event that was nationally televised but drew sparse crowds at the University of Nevada-Las Vegas' campus arena.

A crowd of about 6,000 watched the McEnroe-Connors match Friday night, but only about half that showed up for the final . . .

Stefan Edberg of Sweden upset countryman Henrik Sundstrom, 6-2, 6-4, 6-2, in the semifinals of the $200,000 Young Masters in Birmingham, England.

Edberg will play Boris Becker, 17, in today's final. Becker beat Sammy Giammalva, 7-6, 6-3, 6-3. Giammalva had eliminated top-seeded Mats Wilander.
