Jane Mason, a veteran campaigner who won the first of her two titles in this event in 1965, won the medal in the 60th annual Maryland State Women's Amateur championship at Kenwood yesterday with a three-over-par 74.

Pamela Smyth of Congressional won the one-day senior championship, her third, played in conjunction with this tournament. Her 82 beat Bethesda's Laura Miller by four strokes.

Mason, a small woman from Nassawango Country Club on the Eastern Shore, was playing the Kenwood course for the first time.

"I thought of passing this one up with all the good young golfers entered," she said. "But I thought I'd give it a try."

Mason's last Maryland State title was in 1974. She has been the medalist in this tournament five times.

Mason played with Sally Voss, the sunny-natured Congressional entrant, who won this title in 1978 but since has been too busy with her studies to compete in the East. However, Voss did win the California State Amateur and played in the U.S. Women's Open at Nashville last week.

Voss was a stroke behind Mason, along with Lisa Abood of the host club and Cindy Davis of Belair, the 1979 Maryland Junior Champion.

Patricia Thompson, the defending champion who was exempt from qualifying, drew Sharon Briggs of Montgomery Village as her first-round opponent Tuesday. Briggs recently lost in the final of the women's District championship.

Mason was out in 37 and home with the same score. She bogeyed the second, third and fifth holes when she had trap trouble, but birdied the par-5 seventh with a 10-foot putt. She birdied the short 13th when she put a three-wood short 13th when she put a three-wood shot seven feet from the hole and made the putt.
