David Patterson and David Gildea each won two matches yesterday at Woodmont's South course to reach today's final of the 26th annual Bobby Gorin Memorial Junior Championship.

Gildea, a senior-to-be at Georgetown Prep, will play Patterson, a Dulaney High junior, in this morning's 7:30 final, scheduled for 18 holes.

Gildea, the Interstate Athletic Conference champion, shot 83 in Monday's qualifying and survived a six-way playoff for one of the final three spots to get into the tournament. He is making the most of it.

Gildea played steadily and "made a lot of pars" to defeat Bert Moreno of Rockville, 3 and 2, in his semifinal. Gildea, 17, who lives in Bethesda and plays out of Kenwood, eliminated Geoff Gonella of Columbia Country Club in a morning quarterfinal, 2-up.

Patterson, 16, who lives in Lutherville, Md., and plays out of Hillendale, north of Baltimore, was two under par in his morning round and overwhelmed medalist Jeff Bucaro of Herndon, 7 and 6.

Patterson was fourth in the Maryland state high school tournament last fall and recently held the lead after two rounds of stroke play in the South Atlantic Junior before finishing fourth with a final-round 84.

Patterson cooled off to two over par in an afternoon semifinal, but was still good enough to defeat Mike Pike of Temple Hills, 3 and 1.

"I'm confident," said Patterson about the final. "I'm playing well. When I'm putting good, I can score well."

Pike defeated Fred Widicus, the Emmet Schoolboy champion, on the 19th hole in the morning. Moreno defeated David Colodny of the host club, 3 and 2, in his semifinal. Colodny made a hole in one on the fourth hole yesterday.

In the ages 14-15 final today at 7:40 a.m., Tom Iredell of Rockville will play Kevin Walsh of Meadowbrook, Pa.

Kim Makowka of International beat Kevin Dillard of Burke, 6 and 5, to win the 13-and-under championship.
