Sally Voss of Congressional County Club chipped in for an eagle 3 on the eighth hole for a 3-up lead and went on to defeat Liza Abood of Kenwood, 4 and 3, for her third Women's Distict Golf Association championship yesterday at Belle Haven Country Club.

Voss, also a winner in 1978 and 1979, will take the trophy and run. She will leave Sunday for the University of California-San Francisco to begin her third year of medical school -- "I'm halfway there. I have the M in M.D."

The abood sisters should rejoice at her departure. Voss defeated June, 19, in a Thursday seminifal and the 23-year-old Liza yesterday.

Liza, an assistant basketball coach at Holy Cross Academy and substitute gym teacher at Bethesda-Chevy Chase High, trailed by two holes but had a chance to pull, back into the match on the par-5 eighth hole.

Both hit good drives and second shots, and Voss was away, about 70 feet from the hole. Using her pitching wedge, she chipped the ball low, but it rolled uphill and into the cup. Abood tried to match the eagle but when her chip shot ran past the hole she was 3 down and visibly upset.

Abood missed a three-foot par putt at the ninth hole to remain 3 down and lost the par-3 10th hole when Voss hit a tee shot 10 from the hole and made par.

Voss' only bad hole was the par-4 11th but Abood could do no better than a matching double-bogey 6.

Voss won the match at the par-4 15th when she chipped up inches from the cup on her third shot and Abood missed a long birdie putt.

Karen Jones of Argyle, last year's WDGA champion, defeated Ruth Ann Verell of Belle Haven, 5 and 4, to win the championship consolation.

Chris Lebiedz of Army Navy beat Blanca Fortin of Columbia, 4 and 2, to win the first flight.
