Warren (Cobby) Webb of Greencastle parred the first extra hole and defeated Jim Lawrence of Rising Sun, Md., to win the 23rd Bobby Gorin Memorial junior golf tournament yesterday at Woodmont South.

Neither finalist broke 80 and Lawrence took three straight double bogeys on the front nine to lose a two-hole lead. Webb, a senior at Paint Branch High School, shanked a shot on the front nine and hit two lakes on the back nine, but gamely scrambled for pars on the 13th and 16th holes.

The golf was less than scintillating, but the drama was high. Both golfers had to sink testing four-foot putts for par on the 18th hole to force the match into an extra hole.

On the par-4 first hole (the 19th), Lawrence, who plays out of Chantilly Manor, yanked his tee shot to the left. Trees restricted his swing and he punched an iron second shot that hit just over the green, rolled on a gravel cart path and stopped 50 yards past the green. With dense trees between him and the green, Lawrence lofted his third shot over the other side of the green. He then chipped up 15 feet short of the hole and missed his putt. Webb two-putted for par from 15 feet to win the match.

Webb said he has played 180 holes of golf in a week and a half. "I think I am overgolfed," he said. "If either of us played well, he would have beat the other guy easily."

Webb won his morning semifinal match by defeating Keith Abbott of Lakewood, 2 up. Webb held a one-hole lead going to the 18th hole and won the match when Abbott had tree trouble on the par-5 hole.

In his semifinal match, Lawrence won the 17th hole with par for a 1-up lead and defeated Bob Donlick of Smyrna, Del., 1 up, in his semifinal.
