Gill FitzHugh of Army Navy survived charges by Ken Weakley and Rob Black, a rain delay and closing-hole putting miseries before posting 74-217 and a two-shot victory in the Northern Virginia Amatuer golf tournament yesterday at River Bend.

Black, the District amateur champion from Army Navy, finished second at 219, followed by 1978 NVA titlist Tony DeLuca of Chantilly and Jamie Salyer of Pinecrest, 220.

FitzHugh, 32, twice runner-up in this tournament, bogeyed three of his final four holes but the issue had been settled long before, when Black and last year's champion Weakley of Pinecrest faltered.

"I felt like we were out on the course for about 12 hours," said FitzHugh, who in 1973 beat his brother Woody, now a PGA Tour player, in the final of the District Amateur.

The stocky player with the short backswing started the day three strokes ahead of Weakley and six ahead of Black.

Weakley birdied three of the first four holes. He pulled within one stroke of FitzHugh with a 25-foot birdie putt at the par-4 fourth hole. FitzHugh bogeyed that hole when he drove into a sand trap.

Weakley quickly dropped out of contention by taking bogey on three of the next five holes. He tied for fifth at 75-2219

After nine holes, rain interrupted play with FitzHugh leading Weakley and Black by four. Black, playing several groups ahead of FitzHugh, had played 10 holes in two under par before the rain.

After a one-hour delay, FitzHugh bogeyed the 10th hole, allowing Black to pull within three shots. Black birdied the 12th hole to go three under par for the day, but drove far right and double bogeyed the par 5 14th hole to fall out of the hunt.

FitzHugh prolonged the suspense by missing a 1 1/2-foot putt at 15 and a three-foot putt at 16, both bogeys. FitzHugh parred the 7th hole and bogeyed the par-4 finisher when he hit beyond the green in two shots.

"I really didn't know how I stood," FitzHugh said. "My goal for the whole day was to make pars. I was doing that pretty well until I went to sleep on that little putt at 15."
