Sally Voss' toughest opponent may be jet lag in this week's Women's District Golf Association Championships at Springfield Country Club.

Voss graduates today from Stanford with a degree in biology. Monday, while the rest of the field qualifies, she will fly home. She opens defense of her WDGA title Tuesday, when match play starts.

Last year, 21-year-old Congressioal Country Club golfer won the San Francisco city championship, the Maryland Women's Amateur and was runner-up in the Middle Atlantic.

Her coach at Stanford, who helped her game considerably, is former PGA Tour Player Bruce Summerhays.

Voss, whose family lives in Bethesda, will attend medical school at the University of California-San Diego next fall.

"The thing that impresses me about Sally is that she is a vary solid player, plus a very long hitter," said WDGA President Ruth Ann Verell, Springfield has three lengthy par-3 holes.

"She'll outdrive just about anybody and she has national competitive experience," said Verell. Voss carries a one handicap.

Betty Looney of Army Navy is the only other former WDGA champion in the field of 98.

Other low handicappers are University of Maryland women's basketball player Liza Abood of Kenwood (3), Sharon Briggs of Montgomery Village (4), Carol Davies of Washington (6) and Tina Marlowe of Woodmont (7).
