Bob Boyd, the new Woodmont pro, fired a course-record, eight-under-par 62 at Bretton Woods to take a four-shot lead over three-time champion Marty West and TPC Avenel's Tom Gross into today's final round of the Maryland Open.

Boyd, of Gaithersburg, added his stunning score yesterday on the River Road layout to an opening 71 and stands at 36-hole 133. West, a veteran amateur who lives in Rockville and plays out of Columbia Country Club and Avenel, made seven birdies for 66 and a tie at 137 with first-round co-leader Gross (69 yesterday).

Glenn Barrett of Glenn Dale (70) and Jack Skilling of Columbia CC (68) were next at 138, followed at 139 by Fred Gibson of Cedar Point and Dennis Winters of Prospect Bay (70s).

Boyd "is a heck of a player, we all knew that," said West, who will play in the final group with him today.

It was not the first course record that has fallen to straight-hitting Boyd, 34, a 1977 graduate of the University of Maryland who this winter replaced retiring Tony Marlowe as Woodmont's head professional.

"I've had a lot" of course records, Boyd said. "I've kind of lost track. At one time it was about 20.

"Actually, my low round is 60. My lowest competitive round was 63." Until yesterday.

"It's exciting," he allowed. "I played very well the last two days."

Where the putts failed to drop for Boyd in Monday's opening round of 71, they dropped all over the course.

He birdied his three opening holes, and 6, 10, 11, 13 and 17. He had a chance for a 61, but three-putted the 15th hole for par 5. He had nines of 31.

"The key to my golf is my driving ability," said Boyd, who briefly played on the PGA Tour, in 1983-85, and in 1988 won the National Club Pro championship plus several tournaments in the Carolina PGA section.

"I don't get in the trees and take penalty strokes. Driving is my strength. It's definitely the key," he said.

"They're not supposed to be in this league, are they?" marveled West at Boyd's jewel of a round. West birdied the final four holes of the front nine for five-under-par 30. He bogeyed both back-nine par-3s and three-putted his final hole from long range, also for bogey.

Gross, in his second year at Avenel, bogeyed his final hole after yanking his drive left and said he did not hit nearly as well as Monday when he shared the lead with Barrett at 68.
