Jim Estes of Rockville, winner of this event two years ago, parred the first hole of a playoff against Joe Greenawalt of Rockville to win the medal in Maryland Amateur qualifying yesterday at Columbia Country Club.

Estes of Bethesda Country Club, and Greenawalt of Kenwood had shot 71, best among 177 golfers trying for 31 qualifying spots for match play, which begins this morning. The field was the second largest for this event.

Buddy Peoples of Crofton, as defending champion, was an automatic qualifier.

Ricky Touma of Olney was next at 72, followed at 73 by Henry Blue of Baltimore, Tim Moylan of Argyle, Bryan Holland of the host club and Steve Hall of Tantallon. At 74 were Tony Ciconte of Columbia Country Club, Steve Cartano of Baltimore and Joe Vennari of Ellicott City.

Marty West is trying to win his eighth Maryland Amateur (Ralph Bogart's 10 titles is the Maryland record) over his home course.

West, of Rockville, qualified with a 75 but struggled with his putting. He three-putted the sixth hole from 12 feet and three-putted the eighth hole from four feet, shoving his short birdie attempt 2 1/2 feet past the hole. He bogeyed both holes.

"That shook me up," West said. "I totally lost my confidence. I had started decelerating, trying to guide it instead of hit it. Hopefully between now and tomorrow I'll find something."

Estes hit out of bounds at the sixth hole and took double bogey. He also bogeyed the 16th and 17th holes. But he made his third birdie at the 18th, after hitting a 7-iron approach shot six feet from the hole.

Greenawalt hit a 3-iron second shot to within three foot of the hole at the par-4 finishing hole. "That was the best 3-iron I've ever hit in my life," he said.

Greenawalt, 21, was Kenwood club champion two years ago. He is studying architecture at Maryland.

Peoples shot a practice round of "about 74 or 75" yesterday.
