Ron Terry, who played two years on the PGA tour, birdied the final hole for a six-under-par 66 yesterday and a one-stroke victory in the Lee Elder Celebrity Pro-Am golf tournament at Langston.

Terry's two-day total of 135 beat Fred Gibson, the first-round leader, who shot a 69 yesterday, but missed a 12-foot birdie putt on the par-4 finishing hole that would have forced a playoff.

Terry, of Edgewood, Md., won $2,000 of the $15,000 purse. Gibson, the former assistant pro at Fort Meade, won $1,000.

In a three-way tie for third place at 138 were George Wallace of Atlanta (69-69), Nate Starke of St. Petersburg, Fla., (69-69) and Bob Strable of Atlanta (71-67).

Terry did not make a bogey yesterday.

"I played all of the holes pretty good but the key hole was my final one," Terry said. "(Saturday) I only made par on that hole but my approach shot was better today."

On the final hole, Terry's good tee shot left him 80 yards from the pin. He chose a sand wedge and knocked the ball eight feet from the cup to set up his sixth birdie of the round.

Gibson's attempted birdie putt from 12 feet rolled two inches to the right of the cup .

"I played as good as I could," Gibson said. "I hit a lot of good putts. I'm happy to finish second but, of course, I wanted first place."

Gibson played consistently, hitting 17 greens. But he missed a two-foot birdie putt early in the round and three-putted on the 17th.

Terry was a PGA tour player in 1979 and 1980. For the last two years he has been playing the minitour in Florida where he said he has been quite successful.

"I am intending on getting back on the PGA tour," Terry said. "When I do go back out there I want to be able to back myself and I'm trying to get the necessary finances by playing the minitour."

In the exhibition match that started yesterday's events. Lee Elder, Lee Trevino and Greg Morris played a nine-hole exhibition before an estimated 1,000 spectators.

Trevino, one of the biggest stars of the PGA tour, shot 32, four under par. Elder, the Langston concessioniare and touring pro, shot 34. Actor Morris hacked around.

Trevino stayed and talked to fans and signed autographs for two hours before departing.
