Mark Lye scored his 10th 3 of the day on the final hole for a birdie and an eight-under-par 63 that gave him a three-stroke lead yesterday in the first round of the $250,000 Pensacola (Fla.) Open PGA tournament.

Fuzzy Zoeller, who needs a tie for fourth or better to win the PGA Tour money-winning title, shot a 68. Hal Sutton finished his schedule last week and holds the money lead for the 10-month tour, $426,668 to $415,689. Zoeller received medical treatment for a chronic back problem after completing his round on the 7,093-yard Perdido Bay course . . .
