Jeffrey Roth, of Flint, Mich., won a golfing marathon played under uncertain skies at PGA National Resort & Spa in Palm Beach Gardens, Fla.

Adversity had descended upon Roth, 36, before he attempted to reach the top rung among his peers. The PGA head professional at Flint (Mich.) Golf Club had endured a pair of heartbreaking final-hole losses in the 1992 Michigan Open and Michigan PGA Championship.

But Roth’s game was in perfect working order at PGA National, despite rain and lightning forcing suspension of play five times during the first three days. He sank a 15-foot birdie putt on the sixth hole of the final round to snap a tie with defending-champion Ron McDougal, of Purchase, N.Y., and cruised to an even-par 72 and a two-stroke victory. Roth earned a first-place prize of $32,000 in his seventh appearance in the PGA Professional National Championship.

John Lee, of Naples, Fla., sank a 40-foot birdie putt on the 18th hole for a 72 and took runner-up at 277. McDougal struggled to a 73 and landed in a five-way tie for third place at 278 with Todd M. Smith, of Peru, Ind., Pete Oakley, of Lewes, Del., George Bowman, of Orchard Lake, Mich., and Walt Chapman, of Knoxville, Tenn.
