Webb Heintzelman of Washingtonian parred the 18th hole to score a 1-up, come-from-behind victory over Rob Black of Army Navy for the Bubby Worsham golf championship yesterday at Bethesda Country Club.

"Well, I guess you won't have to qualify for the golf team this year," said Heintzelman's coach at Whitman High, where he will be a senior this fall.

Heintzelman, the 17-year-old bespectacled area junior golfer of the year showed poise as he trailed for most of the match. He didn't pull even until the par-4 15th hole, where he chipped into the cup for birdie from 30 feet with a pitching wedge.

The match was even heading to the 18th. Black hit an iron off the tee on the par-4 hole, but pushed it into trees to the right. Heintzelman's tee shot caught the right rough, but his second shot found the green, 30 feet beyond the pin.

Black, stymied by a pine tree, played a safe second shot and was still in rough. Black's third shot fell short, into a bunker, and he blasted out to 20 feet. Heintzelman putted to within two feet. When Black missed his 20-footer and took double-bogey 6, he conceded par and the match to Heintzelman.

For most of the day, it had been a frustrating round for Heintzelman, who hits a high, controlled fade. He had missed several makeable putts, including two five-footers on Nos. 6 and 8, and an eight-footer on the 12th.

"I was playing against a real good player," he said. "Somewhere I needed to drop a putt." Instead, he dropped the dramatic chip on No. 15.

Heintzelman birdied the par-4 opening hole but lost the next three holes to Black, the District Amateur champ from Vienna who plays on the University of Florida team.

Black, who survived two extra-hole matches earlier in the tournament, birdied the par-5 11th hole with a four-foot putt for a 3-up advantage.
