Tim Simpson withstood late charges by John Mahaffey and Davis Love III to win the Walt Disney World Classic by one stroke yesterday in Lake Buena Vista, Fla.

Simpson, the leader throughout the tournament, finished with 71 on the 7,190-yard Magnolia course for a 24-under-par total of 264. His previous rounds were 64 on the Magnolia, 64 on the Lake Buena Vista Course and 65 on the Palm.

Mahaffey closed with 64 for second at 265, Love 67 for third at 266.

Mahaffey began the day eight strokes behind Simpson, but had a chance to tie with a birdie putt on No. 18. It was inches short and to the left.

"Unfortunately, I misread the putt on 18 and the rest is history," Mahaffey said. "I felt I would have to shoot in the 50s to catch Tim."

Love started the round tied for second with Payne Stewart, six back. He came on and put some pressure on Simpson until bogeying 14, hitting his second shot into water fronting of the green.

Simpson, the defending Disney champion who hadn't won this year, earned $180,000 for his fourth victory in 13 years on the PGA Tour.

He went into the final round 23 under par, in position to set a scoring record, but appeared to play nervously and managed only two birdies and one bogey. The tour record is 27 under par.

Stewart, who set a course record Friday with a 61, slid to 76 -- 275.

Seniors:

Lee Trevino, with a 67, created a six-way tie for the 36-hole lead in the 54-hole, $500,000 Transamerica Senior at Silverado in Napa, Calif. Trevino, No. 1 in 1990 Senior PGA Tour money, made up six shots on first-round leader Jim Dent, who took 73. With them at 140: Orville Moody, Rives McBee, Gary Player and Lou Graham.

Amateur:

Vicki Goetze shot 1-over-par 74 in windy conditions as the United States held a commanding lead after the third round of the women's World Amateur in Christchurch, New Zealand.

Karen Noble supported Goetze with a 79 as the defending champion U.S. side posted a three-round total of 444, seven ahead of second-place New Zealand.
