Bruce Benedict and Dan Disrud played the final seven holes in six under par, including an eagle on the 16th hole, and shot 66 to take the opening-day lead in qualifying for the Belle Haven Four Ball golf tournament yesterday.

Benedict, a former Reston resident now living in Plainwell, Mich., and Disrud of Apopka, Fla., had five birdies and a bogey for a six-under-par best-ball score.

Disrud hit some tremendous tee shots, including a wind-aided 340-yarder at the par-5 16th hole. He hit an eight-iron second shot onto the green and sank an eight-foot putt for the eagle.

"We felt like we were going to break loose before we teed off on the seventh hole, even though we hadn't made any birdies yet," Benedict said. "From that point on we started to play bold."

Disrud made their first birdie with a putt from eight feet at the long par-4 eighth hole, and made his fourth birdie with a 20-foot putt at the par-4 finishing hole. Benedict contributed a birdie at the 14th hole. They covered the back nine in 30 strokes.

Bill Murphy (four birdies) and Brian Johnson (three) of Congressional are second, 67.

The zaniest round belonged to third place Gray Hamilton and Buddy Jose of Tantallon, who had two eagles and a double bogey for 68. Hamilton eagled the fourth hole and chipped in for birdie on the sixth. Jose chipped in for birdie on the eighth and sank a 25-foot eagle putt on 16.

Sixty-eight teams tried to qualify yesterday. Another 70, including former U.S. Amateur champion Vinny Giles and partner Dave Wysong, will play today in qualifying for 15 spots in the championship flight.
