Jim Estes of Rockville won the final eight holes of the match, the last with a 25-foot birdie putt, and overwhelmed Tim Moylan of Beltsville, 8 and 7, to win the 65th Maryland Amateur yesterday at Congressional Country Club's gold course.

Estes, of Bethesda Country Club, lost the first four holes of the scheduled 36-hole match as Moylan played the holes in one under par.

But then the straight-driving Estes took command. He knocked in a 50-yard sand wedge shot for eagle-3 on the sixth hole to pull two down, and, after the morning 18 holes, the University of Tennessee golfer had squared the match.

"Early on, I got into a syndrome of playing him instead of the golf course," Estes said.

In the afternoon round, trouble began for Moylan, 22, a senior-to-be at the University of Maryland who plays out of Argyle Country Club. He bogeyed holes four through nine while Estes parred them all, and Estes was quickly 6-up.

Estes reached the par-5 10th hole and two-putted for birdie to go 7-up. The match ended on the par-3 11th hole of the afternoon when he rolled in a 30-foot birdie putt.

"I don't have that much match-play experience," said Moylan, playing in the event for the first time. "I hit a few bad drives and a few bad chips and made six bogeys in a row. I got on the bogey train and couldn't stop it."

Estes, 20, who has played in this tournament since he was 16, played one-under-par golf after his opening four holes.

He said he was not mentally into the match until his eagle. "That really gave me an uplift," he said.
