Fulton Allem of South Africa, the least-known of the eight golfers in the Million Dollar Challenge, shot a 6-under-par 66 and took the lead after the opening round in the chase for the richest prize in golf history.

Allem, a last-minute replacement in the Sun City, South Africa, tournament, won the first of four $50,000 prizes for the best round each day. Aside from these bonuses, only the winner will get a check Sunday -- for $1 million.

A three-foot putt on the final green earned Allem his seventh birdie and gave him a one-shot lead over Ian Woosnam, top money-winner on the European tour.

Tied for third at 68 were Nick Faldo of Britain, the reigning British Open champion, and Jose Maria Olazabal of Spain. Bernhard Langer of West Germany and David Frost of South Africa were next with 70s; Lanny Wadkins had a 71 and Curtis Strange a 72 . . .

The matchup of PGA neophyte Kenny Perry and LPGA veteran Sally Little combined for 10 birdies in a 62, giving them a three-shot lead after the opening round of the $650,000 Mixed Team Classic in Largo, Fla.

The pair sank five birdies each on the front side and the back side and avoided bogeys.
