David Patterson of Lutherville, Md., broke up a deadlocked match by winning three straight holes on the back nine to earn a 2-and-1 victory over David Gildea of Bethesda that gave him the championship of the 26th Bobby Gorin Memorial Junior golf tournament yesterday at Woodmont South.

Gildea, 17, who plays out of Kenwood, evened the match by winning the 10th hole with par and the 11th with a 15-foot birdie putt. But Patterson's job was made easier at the 12th hole, when Gildea hit into a lake; the 13th, when Gildea drove into woods, and the 14th, when Gildea drove into sand.

Gildea won the par-3 15th hole with par to pull within two, and the 16th was halved in par. The match ended on the 17th green, when Gildea missed a birdie putt from 12 feet.

"I don't think he played his best game," said Patterson, 16, a junior at Dulaney High School who plays out of Hillendale, north of Baltimore. Patterson made two birdies and finished at five over par.

Gildea, the Interstate Athletic Conference champion who helped Georgetown Prep win the IAC team title by 63 shots, made the match-play field in a playoff after shooting 83. He said his game -- with which he was just three over par for 34 holes Wednesday -- deserted him yesterday.

"I thought I was out of a slump," Gildea said. "I couldn't get anything going today."

Gildea hit into the lake guarding the green at the par-3 12th and lost to Patterson's par. Gildea then pulled his tee shot deep into the woods on the tough, dogleg par-4 13th hole and took triple bogey to go two down.

"I didn't par that hole once in five rounds," Gildea said.

Kevin Walsh of Meadowbrook, Pa., recovered from two down to defeat Tom Iredell of Rockville, 1 up, to win the 14-15 title. Walsh, 14-15 runner-up in last week's Bobby Bowers Junior, was Iredell's house guest this week.
