Gary Mankulish served notice yesterday that he has regained the form that made him the area's top amateur two year's ago, teaming with host Geoff Robertson to win the Columbia Country Club member-guest golf tournament, 5 and 4, over Jerry Nye and Ralph Bogard of Chevy Chase.

On the 14th hole Robertson, who had been letting Mankulish carry most of the load after winnig the third hole, stuck a seven-iron a foot from the hole for a birdie.

Up to the point, Mankulish of Prince Georges had amazed the rain-soaked gallery with some great recoveries worthy of Ben Crenshaw, the tour golfer who gets out of trouble best.

Mankulish trapped his drive on the par-four ninth and hit a 200-yard four-wood on the green. He sank a 30-foot putt for a birdie giving his team a 3 up advantage.

The real break came on the 11th hole. Nye was just off the green in two and Mankulish came out from under trees for this second shot, 75 yards short of green. He chipped up leaving himself a 27-foot putt. He made that for par.

Nye elected to putt from off the fringe, rolled the ball 10 feet past the hole and missed the comeback putt for a bogey.

Nye and Bogart couldn't get it together yesterday. Nye made the only birdie for his team, sinking a 27-footer on the first hole. Robertson parred the third to even the match. Mankulish bagged a six-footer for the only par in the foursome on the sixth to go 1 up and his opponents never regained the honor.

Mankulish parred the eight to go 2 up and then made his spectacular birdie on the ninth. He actually put the match away with his unusual par in the 11th.
