Henry DeLozier of Columbia Country Club, a two-time Masters participant, led the way in the opening round of a Middle Atlantic Golf Association championship at Five Farms today with a one-over-par 71.

A stroke back were Dr. Jack Shamblin, of Hurricane, W. Va., and Jay Sigel of Philadelphia.

The slick greens and the strong wind thwarted would-be par breakers. Marty West, the defending champion and, former Walker Cup player, had 77.

Dan Kardash and Eddie Johnston, both members of Five Farms, came in with 73s. Kardash is the current club champion. Ken Mattiace, Jericho, N.Y. also had 73.

A fieldl of 126 teed off and 100 and ties survived the first cut virtually everybody who handed in a card. The field will be cut to 60 and ties Saturday and will be down to 40 and ties on Sunday.

DeLozier had two bogeys and two birdies on the front and two bogeys and a birdie on the back. Sigel had a chance to tie deLozier, his playing partner, on the 18th but took a bogey. DeLozier made a fine chip after a poor drive and second shot and holed a four-foot putt. Shamblin had 34 going with two birdies and a bogey but came back with 38, bogeying three of the last five holes.

DeLozier bogeyed the second hole, missing a three-foot putt, but birdie the 575-yard sixth from eight feet. He bogeyed the ninth, 10th and 11th but came back to birdie the 12th on a four-footer after an eight-iron, approach. He made birdie two on the short 13th, hitting nine-iron eight feet away and making it. He bogeyed the 16th when he three-putted but parred the last two holes.
