Two Army Navy clubmates, Nancy Hollenbeck and Betty Looney, coped with gusty winds and fast greens in carding net 72s to share the first-round lead in the Women's District Golf Association Class A Keefer Cup yesterday at Chevy Chase Club.

Hollenbeck, who won the Keefer in 1975, had the lowest gross round of the day, 79, and subtracted her seven handicap for her one-over-women's par score. Looney, two time WDGA champion, had 83-11-72.

"It's just a tough gold course," said Looney of the Chevy Chase layout, made more difficult because of the wind and because the lush rye-grass fairways, seeded in the offseason, allowed tee shots little roll. "The fairways were very heavy."

Looney said she hit the ball solidly but her putting was only 50-50. She needed 36 putts.

Looney double-bogeyed the 390 yard, par-four finishing hole when she "chili-dipped" a chip shot and three-putted after hitting two fine shots to be close to the final green.

Hollenbeck was pleased with her work around the greens as she one-putted six times for 31 putts. She three-putted the par-three ninth hole.

TR FOR ADD ONE Marian Lewis of Woodmont (89-14-75) and WDGA President Ann Heuer of Congressional (86-11-75) shared second place, followed at net 76 by Barbara Leonard of Westwood, four-time champ Rebecca Doman of Argyle, Diane Rankin of Montgomery Village and Tina Marlowe of Argyle.

Marlowe's mother, Rosemay, was one of five cancilations in the field, which dropped to 56. She locked her keys in her car and was unable to get her golf bag from the trunk.

Sue Keeney, last year's champion, took her many WDGA trophies and moved to Orlando, Fla., where she is now a teaching professional.

The wind pushed scores skyward so that most of the field in this event, limited to 14-and-under handicaps, failed to break 90. Thirty five players, net 83 and under, qualified for today's final round.
