Thunderstorms interrupted the second qualifying round for the 29th Belle Haven Four Ball championship yesterday with six foursomes still on the course.

The plan calls for the golfers who were interrupted yesterday to finish their rounds today. In the event of ties for the round of 16 in the championship flight, the spaces will be filled by names drawn from a hat.

Vinnie Giles, former U.S. and British amateur champion, and Dave Wysong, tournament chairman, were three under par when they were forced to come in cut of the rain after the 16th hole. However, even if they par in today, they will be far back of the two teams that tied at seven-under 65. These were John Long, Evergreen club champion, paired up with Dave Allen, the 1975 District Amateur titlist, and the duo of Brian Willard of Argyle, one of the top amateurs in the Washington area, and Dave Sterns, the Tantallon club champion.

Two strokes back among the finishers was the University of Maryland team of Bob Boyd and Bob Darling, with a 67.Butch Mielke of Crofton and his late-minute partner. Fred Reese of the University of Maryland, shot 68 to tie for third place with Arthur Bryant of the host club and Max Chapman of Winged Foot, son of former amateur champion Dick Chapman.

The strong Columbia team of Perky Cullinane and Henri deLozier were at 69, tied with Reagan O'Rourke, 17-year-old Churchill High School student who has dominated the junior ranks, and Tim Sughrue, North Carolina State golfer.

Willard and Stern had eight birdies and one bogey in their round and had seven one-put greens.

On the par-five 12th, Willard was never on the fairway but he managed to come up with a birdie. He put his third shot three feet from the cup and made good. Sterns rolled in a 30-footer on the 14th and a 15-footer on the 15th to maintain the hot pace. The team's only bogey came when Willard three-putted the 17th. Each man had a 70 on his own ball.

Long and Allen parred the first three holes, then Long sank a 40-yard wedge shot from the rough for an eagle-3 on the fourth hole. The pair parred the next four holes but bogeyed the 228-yard ninth.

Long birdied the 10th from 15 feet and Allen made good on a similar putt on the 13th. Allen also nailed a 15-footer for another birdie on 15 and a 10-footer on the 16th to shave another stroke off par. Long stuck a wedge shot inches from the pin on the 18th for the team's last birdie.
