Gary Lipski of Hillendale three-putted the final green but still managed a first-round 70 for a two-stroke lead in the 72-hole Middle Atlantic Golf Association Amateur today at Woodholme.

Lipski, 32, made six birdies and appeared in position to open a large lead when he reached the par-5 finishing hole in two shots.

But he struck his 30-foot downhill approach putt too firmly, missed an eight-footer coming back, and settled for a par.

Nathaniel Crosby, 20, son of the late Bing Crosby, survived a shaky start and made three birdies on the back nine to tie for second with Joe Records of Hunt Valley, Bob Friend of Richmond and Dave Abell of Fort Pierce, Fla.

"There's some great holes out there. It tests your nerves quite a bit, hitting over all that water," said Crosby, the 1981 U.S. Amateur champion.

Crosby bogeyed the first and third holes. He was in danger of going three over par when he popped up his tee shot on the par-4 fourth. He failed to reach the green with his second shot, but chipped up and saved par with a six-foot putt which "helped me quite a bit. After that I hit the ball fairly well."

From that point, he did not make another bogey. Crosby birdied No. 10 and made it back to even par with a six-foot birdie putt on the par-5 16th. He finished at one under par when he curled in a 20-foot uphill putt on the par-5 finisher.

Brian Lehnhard of Evergreen, Washington area junior of the year, had the strangest round of the day, with six birdies, an eagle, a triple bogey and two double bogeys for a 76.
