Marty West, who has occupied area amateur golf headlines for 12 years, finessed the wind and rain at Congressional Country Club yesterday to take a one-stroke lead at 142 in the Middle Atlantic Amateur golf championship.

West shot a second consecutive 71 and pulled ahead of first-day leader Gary Marlowe, who slipped to 143 with a 74. Perky Cullinane and Gill FitzHugh, who were tied for second place with West on Thursday, each had a 77 yesterday.

However, both West and Marlowe felt the breath of several fine young golfers, including Paul Ryan, the 1979 winner of the Middle Atlantic Open, and Henry Blue of Baltimore. Both were at 146. One stroke behind was Barry McCarty, the current District Amateur champion.

The par-72, 7,075-yard Blue Course at Congressional played much longer yesterday because of intermittent rain that was heavy at times. The greens held well and everyone shot for the pin, but the traps were heavy and difficult to negotiate.

West, Marlowe and FitzHugh played together in the last threesome. West started by making a birdie on the first hole with a 12-foot putt. He bogeyed the second hole when he three-putted and finished with a 34 with birdies on the fourth and sixth.

On the back nine, West birdied the 10th, bogeyed the 11th and 14th and then made all other pars.

Marlowe was out in par 36 with two birdies and two bogeys and home in two-over-par 38.

Sullivan birdied the first hole with an eight-foot putt and rolled in six others from five to 15 feet. He did not have a bogey.

Burns, former University of Maryland golfer, shot a 66 that included five birdies and a bogey for a 133 total to remain close to Sullivan, who had a second-place finish in the Bob Hope Classic this year and lost a playoff in the 1979 Buick Open in his only other bid for a victory.
