Ian Woosnam of Wales won the biggest prize in golf history yesterday, clinching the winner-take-all Million Dollar Challenge with a spectacular eagle 2 on the 17th hole en route to a 4-under-par 68 in Sun City, South Africa.

Woosnam, the top money winner on the European tour this year and winner of the recent World Cup, capped his impressive season with a four-stroke victory over Briton Nick Faldo, who closed with a 71. Woosnam ended with a four-round total of 274, 14-under-par, tying the tournament record.

Faldo, playing with Woosnam, trailed by only one shot through the 13th hole, but bogeyed the 14th to drop two behind.

Faldo still had a chance going into the par-4 No. 17 hole, but Woosnam holed a pitch of 165 yards to seal the victory.

Finishing third in the eight-man field was South African David Frost, a regular on the American PGA Tour, whose 72 left him at 280.

Fulton Allem of South Africa, who led each of the first two rounds, shot his second straight 74 to end at 283. That left him tied with American Curtis Strange, who shot 70, and Spaniard Jose-Maria Olazabal (72).

Bernhard Langer of West Germany shot 74 -- 285. American Lanny Wadkins finished with 75 -- 290 . . .

In Largo, Fla., Jane Crafter's 35-foot birdie chip at 17 broke a three-way tie and she combined with Steve Jones on a final-round 68 to win the $650,000 Mixed Team Classic by two strokes.

Neither Jones nor Crafter has won an individual event on the pro golf tour, but they used rounds of 65-69-66-68 to finish at 20-under-par 268 and split the top prize of $130,000. A field of 50 teams, pairing PGA and LPGA players, followed an alternate-shot format. Jones and Crafter overcame a double-bogey 7 at the eighth hole as the LPGA veteran made four birdies of at least 25 feet.

Runners-up Mark McCumber and Debbie Massey, who took a one-shot lead into the final round, missed a half-dozen birdie opportunities and carded a 71. Doug Tewell and Betsy King (68) and the team of Morris Hatalsky and Donna White (67) tied at 271.
