Mark McCumber finished a round of six-under-par 65 with birdies on the last three holes yesterday for a four-stroke victory in the Pensacola (Fla.) Open, the final individual event on the 10-month PGA Tour. He closed at 18-under-par 266 on the Perdido Bay Country Club course and won $45,000, saying afterward, "I finished second and first in my last two starts. With that going on, I kind of wish there were a few more tournaments to play."

Mark Lye (65) and Lon Hinkle (68) tied for second at 270. McCumber became one of eight golfers to win two events on the tour this year, but for the first time no one won at least three. Fuzzy Zoeller and Cal Peete, meanwhile, fell short in bids to overtake some absent leaders. Zoeller needed a tie for fourth or better to overtake Hal Sutton on the money-winning list, but tied for 25th at 280, winning $1,908. Zoeller closed with $417,597; Sutton, the player of the year, finished with $426,668. "Disappointed? Hell no," Zoeller said. "I had a great season, my best. I'm not greedy."

Peete needed 65 to overtake Ray Floyd as the Tour's scoring leader and win the Vardon Trophy. He shot 67 for a 271 total and closed with a 70.62 average. Floyd's average? 70.61 . . .

In Chiyoda, Japan, Gene Littler shot seven-under-par 67 for a total of 276 to win the Coca Cola Grand Slam championship for senior professionals by two strokes.
