Out-of-town dominated the South Atlantic Junior Amateur golf tournament at Crofton yesterday as only four Washington area golfers advanced to the round of 16.

Richard Montefusco of Westwood, Charles Gates of Columbia, Gregg McCullough of Bowie and Dan Bosis of Indian Spring were the survivors.

Tony DeLuca of Chantilly, medalist in the 16-17 class, was ousted by J. B. Whalley of Ocean City, 1 up, in the morning round. Shalley was knocked out in the afternoon by Dan Reardon of North, N.J.

Rhett Butler of Montgomery Village, comedalist in the 14-15 class with Webb Heintzelman of Washingtonian, lost his first-found match to Dick Parkinson of Argyle, 3 and 2, Heintzelman had no problem beating Bob Phillips of Springfield, 6 and 5. The younger group played only one round yesterday.

Montefusco won his morning match against Andy Harris of Hampson, Va., 2 and 1, and defeated Jeff Walter of Springfield, 4 and 3, in the afternoon. Gates eliminated Furman Buddin of Malvern, Pa., 2 and 1, in the morning, but had a tougher time beating Dennis McCarthy of Greencastle on the 20th hole in his second match.

McCullough got by Tom Martel of Washington Golf and Country Club, 1 up, in the morning, and beat Jay Stacy of Springfield, 1 up, in the afternoon. Bosis defeated Larry Corson of Simsbury, Conn., in the morning, 2 and 1, and beat Terry Burke of Congressional by the same score in the afternoon.

Whalley was all even in the morning in his match with DeLuca going to the 18th. Both reached the green in two but Whalley won it with a 15-foot birdie putt. In his afternoon match with Reardon, the match was even going to the 18th and both were on in two. But Whalley three-putted for a bogey and lost the match.
