John Haddock of Annandale High School, playing with an injured hand, was two under par for the 17 holes necessary and defeated Pat Staveley of Bowie High School, 3 and 1, for the 49th Metropolitan Schoolboy golf championship yesterday at Marlboro Country Club.

Haddock, a slender 18-year-old playing his final junior tournament, said he pulled a muscle in his left hand in his opening match Tuesday.

"I had to grip the club lightly and swing easy," he said. "I'm not going to play for awhile, I'm going to let it heal."

Haddock acknowledged that being forced to swing easier might have helped his accuracy on Marlboro's restrictive, wood-lined course. He estimated he was one or two under par for five matches this week, after qualifying Monday with a 77.

Staveley, 18, the younger brother of Middle Atlantic PGA pro Brian Staveley, was playing his final junior match after rallying from a four-hole deficit to win Wednesday's semifinal.

Haddock parred the third hole to go 1 up, and rolled in a 70-foot putt for a halving birdie on the fourth. But the free-swinging Staveley sank a five-foot birdie putt on the fifth hole to pull even.

Haddock dropped a five-foot birdie putt on the seventh hole to again go 1 up, and took a two-hole lead with par at No. 8 when Staveley overshot the green with his tee shot.

Staveley sank a four-foot birdie putt on the ninth hole to pull within one, but fell two down with bogey at the 10th after his tee ball found a very poor lie in the rough. He came back with a four-foot birdie putt at the 11th hole to pull within one.

Staveley squared the match on the par-3 12th when Haddock double-bogeyed after hitting his tee shot into a bunker. Until then, Haddock had two birdies and the rest pars.

Haddock went 1 up by parring the 13th as Staveley three-putted, and went 2 up again with birdie at the par-5 14th hole. They tied the next two holes in par.

On the par-5 17th, Staveley's fairway-wood second shot stopped in high weeds next to a creek, 160 yards short of the green. He hit a wedge back to the fairway, but still was 100 yards away. His fourth shot landed on the green 30 feet to the left of the cup and, after he missed his long par putt, conceded Haddock his two-foot par putt and the match.
