Knowing how tight and narrow the course was, Chris Giza thought she wouldn't need to bring her driver to South Riding Golfers' Club in Chantilly yesterday. She was right.

The Centreville resident, a special deputy with the U.S. Marshal's Service, shot an 8-over-par 80 on the tricky 5,004-yard course to win the medalist honors in the Executive Women's Golf Association Washington metro chapter championship.

"There's too much trouble to get into off the tee," Giza said of her decision to forgo the driver in the tournament, made after playing a practice round at South Riding two weeks ago. "You must hit it right to score. If it's not in the right place, it won't work."

Yesterday, it was her putter that gave her trouble, on Nos. 4 and 12. Giza lost ground when she carded double bogeys on those holes, but she rebounded with birdies on the next hole both times.

Giza is one of 10 golfers--low gross and low net winners from each of the five flights--who will advance to the sectional championship at Nutters Crossing in Salisbury, Md., on Sept. 18.

The winners of the sectional championship move on to the EWG national championship at Doral Golf Resort in Miami this November.

This is Giza's first year with the EWG. She recently moved to the area from Oklahoma, where there was no EWG chapter.

"The whole idea I believe in," said Giza, who has been playing golf for 26 years. "The fact is that women need to do more mentoring. So much is done on a golf course. . . . I believe I have an obligation to help other women. I'd like to see more women involved in golf."

The Washington metropolitan chapter, with its 455 members, is one of the largest chapters in the country.
