Bruce Lietzke sank a five-foot birdie putt with his cross-handed style and won a sudden-death playoff on the second extra hole for the $45,000 first prize in the Wickes-Andy Williams San Diego Open golf tournament today.

Lietzke outlasted Ray Floyd and Tom Jenkins to become the PGA Tour's first two-time winner this year. He won the Bob Hope Desert Classic with a record score last month.

Lietzke, Floyd and Jenkins all birdied the final hole of regulation play for totals of 278, 10 under par on the 7,002-yard South Course at Torrey Pines Golf Club.

Lietzke, five shots back with eight holes to play, came out of the pack with a final-round 68, his 14th consecutive round of par or better this year.

Floyd, who counts the Masters and PGA national championship among his 12 career victories, just missed an eagle putt that would have won it on the final hole of regulation. He tapped in for birdie and a closing 71. The longshot Jenkins, whose only previous triumph came six years ago in Philadelphia, had a closing 70.

Lietzke started the final round in a tie for 12th place -- and apparently doomed his chances by double-bogeying the first hole today -- before catching Floyd and Jenkins, 33, a tour rabbit who had to qualify for this tournament.

Jenkins took a bogey on the first extra hole, leaving Lietzke and Floyd to fight it out for the title.

On the par-3 No. 16, second hole in the playoff, Lietzke put his five-iron tee shot about five feet from the pin and sank the putt after Floyd was short from about 25 feet.

Thus, Lietzke brought his 1981 tour winnings to $102,899.

Floyd shared the lead after 54 holes with Craig Stadler at 207, nine under. Floyd, too, had a double bogey in the final round. He missed by no more than an inch his putt for eagle on the 72nd. Stadler, with a 73, finished two strokes behind.

Jenkins and Floyd each picked up $22,000, and Jenkins hereafter will be spared the agony of qualifying weekly.

A steady rain on the final day failed to cause any disasters although some players complained the footing was slippery.

Lietzke, Jenkins and Floyd did not look like potential winners until late in the final round.

The early leader was George Burns, who won the Crosby Pro-Am last year and is a consistent money-winner.

Burns was 12 under at the turn but could not maintain that pace and slipped to a final 71, leaving him in a tie for fourth place at 279 with Gary Hallberg, who had a final 67, and Jeff Mitchell, a youngster who shot 71.

Jack Renner, who lives in San Diego, had 70 for 280 and a tie with Jim Simons, 71, and Stadler.

Lietzke said he entertained some thoughts of winning the tournament as he began the final round but the double bogey on the first hole changed his attitude.

"It was a very casual round after my double bogey. Really, the thought of winning didn't come to me again until the 13th hole," he said.

Lietzke had to wait about 45 minutes for the playoff since he finished ahead of Floyd, and he said his hands were quite cold.
