Todd Donlick of Smyrna, Del., proved he is a golfer for many age groups when he defeated Kevin Collins of Centreville, Va., 2 and 1, to win the Bobby Gorin Memorial junior golf tournament yesterday at Woodmont South.

Donlick, 16, who plays out of Garrison's Lake Country Club, has never lost in 11 matches at Woodmont and has won the championship in three different age groups.

"I love this course, it's in great condition," said Donlick after defeating Chantilly's Collins in a seesaw match in searing heat.

"That was as tiring as it's ever been for me," said the slender Donlick, a short hitter but smooth around the greens.

The match ended on a strange note. At the par-4 17th hole, with Donlick holding a one-hole lead, each player lost his ball, and Donlick won the hole with a double bogey.

At the 395-yard 17th, Collins, who had pulled to one down with a par at the 14th hole, hit first and hooked his ball over a fence. Donlick pulled his shot to the left, but not as severely as Collins, and the ball hit a tree.

After minutes of hunting, Donlick looked up at the tree and said, "I bet my ball is stuck up there."

He had to return to the tee and hit a provisional just as Collins had done minutes before.

Donlick made a double-bogey six with his stroke-and-distance penalty and won the match when Collins, putting from 15 feet, missed and took triple bogey.

Donlick said he was not thinking about playing in the final when he was three holes down with three to play against Kevin Cusack of Potomac in his morning semifinal. Donlick won the 16th, 17th and 18th holes with par to send the match into an extra hole, and won it on the 19th with par.

Collins eliminated Dennis Spiegel of Alexandria, 5 and 4, in his morning semifinal.
