Marty West and former University of North Carolina teammate Bill Boles continued to show the way in the Fred McLeod Eastern Four Ball tournament at Chevy Chase yesterday with 129, nine strokes under par. Three shots back were defending champions Henri deLozier and Buddy Marucci.

DeLozier and Marucci were involved in a gulf technicality on the par-three fourth. Marucci smoothed the green of spike marks in West's path and it cost him a two-stroke penalty and deLozier one stroke. Despite that, deLozier and Marucci finished with 67 to 64 by West and Boles, who had another hot hand.

The tournament winds up today with 39 players who made the cut at 142 and ties.

West and his partner, playing most of their 18 along with deLozier and Marucci in a steady downpour, started off with bogey on the first hole. But the pair made four birdies on the front and two more on the back.

DeLozier, who confessed that this was the first time he and Marucci had not been in front after three championships, had one bogey and two birdies on the front and another birdie on the 10th before parring in.

Ralph Bogart, the veteran from Chevy Chase, and his partner, Boots Widener, were tied at 134 with the upstate New York team of Bill Gerber and Alan Foster. Another stroke back were Gary Marlowe of Woodmont and Fred Funk of Montgomery Village.
