Gary Marlowe, playing his home course at Woodmont Country Club, shot even par 72 in high winds yesterday and was tied with Gill FitzHugh of Army Navy at 146 at the halfway point of the 72-hole Middle Atlantic Golf Association Amateur Championship. FitzHugh, older brother of Middle Atlantic PGA champion Woody FitzHugh, shot 74.

"I feel like I shot 68 or 67," said Marlowe, 22, the 1978 Maryland Open and 1980 Maryland Amateur champion, who had three birdies. "The hardest thing to do in the wind is to keep your concentration. If you let it bother you, it gets worse and worse.

"I'm hitting the ball pure over my home course. That's a real good combination."

Jim Estes, 17, who led with a first-round 69, shot 83 and was tied for 10th at 152. The Peary High golfer appeared ready to open a big lead when he sank a 20-foot birdie putt on the third hole to go one under par for the day. But he double bogeyed the next hole and three-putted twice for a front nine 40, then dumped an easy wedge shot approach into sand and took double bogey 7 on the 10th hole.
