It will be McCarty against McCarthy in today's scheduled 36-hole final of the 73rd Washington Metropolitan Golf Association Men's Amateur championship at Montgomery Country Club in Laytonsville.

Barry McCarty of Alexandria and Belle Haven Country Club, who won this tournament in 1980 when it was known as the District Amateur, used chip shots instead of approach putts on soggy greens after a rain delay and held off George Mavrikes of Prince Georges, 2 and 1, in his semifinal yesterday.

McCarty will battle fellow 32-year-old and former high school and college adversary Mike McCarthy of Silver Spring and Argyle Country Club in the final starting at 7:30 this morning.

Left-handed McCarthy came in at 2-under-par and overwhelmed Pat Moylan of Argyle, 8 and 6.

"We've locked horns many times," said eight-time Belle Haven club champion McCarty, who played for Ireton High and Virginia Tech against McCarthy, who attended Good Counsel and James Madison. "It's going to be tough because we're similar players. We don't hit it far but we're very consistent."

McCarthy made short work of Moylan, winning the first two holes, taking a 5-up lead at the turn and ending the match on the 12th hole just as an electrical storm descended.

"I got a quick start on him and he hit a couple of bad shots," said McCarthy, who has won the club championship at Argyle twice in seven years. "After that I just kept trying to hit greens and make him work and wear him down. I guess it did."

Mavrikes had chipped into the hole at the 11th green to pull within one. He remained 1-down through the 13th hole when a heavy storm stopped play for an hour.

They resumed on the par-3 14th hole. McCarty hit his tee shot into the right bunker, then blasted out 25 feet short. Mavrikes hit to the left of the green and chipped his second shot to four feet. McCarty, although on the putting surface, then used a 7-iron on the wet green and chipped to three feet. He tied the hole in bogey and remained 1-up when Mavrikes missed his short par putt.

On the next hole, a par-4, McCarty hit the green in two shots and used an 8-iron on the green and chipped a 45-foot "approach putt" to within three feet of the hole and went 2-up when Marvrikes took double bogey.

McCarty said he felt confident chipping on the green: "I've played that shot from the fringe quite often and because the greens were so wet I went with an iron. I don't feel like I was giving away much by using an iron."

McCarty finally won when he sank an 8-foot par putt on the 17th hole.

In morning quarterfinal matches, Mavrikes shot 31 on the front nine for a 4-up lead and eliminated Seppo Iso-Ahola of Robin Dale, 5 and 4. McCarthy ousted Shane Patterson of Norbeck, 2 and 1, McCarty eliminated Jim Sutton of Lakewood, 2 and 1, and Moylan bounced medalist Gary Moore of Crofton, 2 and 1.
