Stocky left-hander Bob Bilbo made four birdies and finished with a 70 at dusk to take the first-round lead of the 36-hole $10,000 Shannon Green Pro-Am golf tournament today.

Bilbo, manager of Montgomery Village's pro shop, made two birdie putts of 15 feet and one from eight feet. He reached the par-5 16th hole in two shots and two-putted for his other bird in his first entry in this tournament.

Bilbo wrested the lead from Tommy Wine, who posted a 71 early and scurried back to Richmond to be with his wife, who recently gave birth to a baby girl.

Amateur Ken Weakley, at 71, was the only other below par on this Eddie Ault-designed layout, made more testing by fast greens and brisk winds.

"It's one of the better and longer golf courses we play," Andrews Air Force pro Art Scott said. "The wind was a big factor, plus all the par 3s played extremely tough," he added.

"On the eighth hole, a 440-yard par 4 dead into the wind with the tallest trees in the country in the middle of the fairway, I hit a drive and a three-wood and I was still short."

Larry Ringer, the Naval Academy golf coach who won the $950 first prize here last year, did not play because he was at West Point rooting his Midshipmen against Army.

Fred Ryder of Bel Air matched par 72.

Melvin Rowe of Fairfax thought he had shot 72 until he looked in his golf bag walking off the 18th green and discovered a Ben Hogan wedge identical to his and called a penalty on himself for having 15 clubs, one too many. Rowe was penalized four strokes and finished with 76.

"Probably one of the kids that cleaned my clubs last night put it there by accident," Rowe said after shooting a strong 34 on the back nine.
