Katherine Marren of Potomac shot a steady, 1-over-par game and defeated fellow Army Navy Country Club player Nancy Hollenbeck of Annandale, 3 and 2, for the Women's District Golf Association Championship yesterday at Kenwood.

Hollenbeck, 56, a retired Navy lieutenant commander, was frustrated in the final of this tournament for a second time, but not without a fight.

Hollenbeck, a former Virginia state women's champion, chipped in for winning birdies at the 13th and 14th holes to pull within two holes.

But Marren, who played collegiate golf at North Carolina State, appeared bothered not in the least. She promptly knocked her tee shot onto the green at the par-3 No. 15 and made a 25-foot birdie putt to regain a 3-up advantage.

Marren then hit a drive 240 yards down the 16th fairway, reached the green with her approach shot and closed out Hollenbeck with par.

"The big difference was I hit my driver well today," said Marren, 22, who played erratically in her semifinal on Thursday. "It has given me a hard time all week. I was all over the course. Today I swung through the ball and had an 8-iron or 9-iron to most of the greens."

Marren said she would try to qualify for both the U.S. Women's Open and U.S. Amateur this summer and hopes to finish her studies at Florida Atlantic in Boca Raton, Fla. She said she plans to play in some upcoming Florida women's minitour events as an amateur.

In the championship consolation, Judy Nelson of Army Navy defeated Carmen Oelsner of Bretton Woods in 19 holes.

MAPGA Pro-Am: Glen Barrett of Glenn Dale shot 63 to win at Prince William, the first PGA victory for Barrett, whose score was the lowest in a Middle Atlantic event this year.

Webb Heintzelman of Montgomery Village had 66 for second place. Mike Ahrnsbrak of Shenandoah Valley and Lon Kinney of Congressional were next at 68.
