Mike Donald of Hollywood, Fla., shot five-under-par 67 to win the pro division of yesterday's Kemper Pro-Amateur golf tournament at Congressional Country Club.

Donald, whose only victory on the PGA Tour was in 1984 when he teamed with Vicki Alvarez to win the J.C. Penney Team Classic, won $750 yesterday.

Bob Eastwood made four birdies and was second at 68.

Another stroke back were former Frederick pro Donnie Hammond, Calvin Peete, Curtis Strange and Jeff Sluman.

Next at 70 were Barry Jaeckel, Lanny Wadkins and Mark O'Meara.

Craig Stadler, a two-time Kemper Open champion, teamed with amateurs Billy Huffman, Henry Higginbottom, Russ Gledhill and John Parziale for net 54 to win the team prize. Stadler also won $750.

Pro Bob Tway, along with amateurs David Chase, Mike McCullough, Thomas Gibbons and John Porter, took second in the team standings with 56.

It was in 1968, during the Tet offensive in Vietnam, that automatic weapons fire shattered Army platoon leader Pete Malphrus' right calf.

Now, 18 years and 13 operations later, Malphrus, 39, is the Montgomery Village head pro and is poised to play in his first PGA Tour event, the Kemper Open.

He qualified by shooting 69 last week in a Middle Atlantic PGA qualifier at Poolesville.

On Tuesday, he hit balls on the practice tee, then played 18 holes with Manor pro Coleman Plecker. His unorthodox, loopy swing was evident; his leg had required a bone graft from his hip and he wears a three-inch lift in one shoe. Also evident were good results; he drove the golf ball long and true.

"I started playing golf as therapy from the injury," he said. For two years, he played in a long-legged cast because "two-thirds of my calf muscle was destroyed. I had skin grafts, surgery, bone infection and massive nerve damage . . . I liked golf so much I decided to get into the business."

Of his first PGA Tour event, he said: "It's a thrill. It's very exciting. Here you have an opportunity to perform or crack in front of thousands of people. It's going to be great because I'm going to have friends and members following me."

Andy Bean woke up yesterday morning with such a sore back that he had to withdraw from the Kemper Open.

But the first thing he did when he got up was withdraw from his 8:21 a.m. tee off time in the pro-am tournament.

Before he officially withdrew and flew home to Lakeland, Fla., he went to the course to apologize to his pro-am partners for not being able to play.

"There's no way I can swing a club right now," he said. "The doctor said if it got worse from Tuesday to Wednesday, there's no way it could be ready for the tournament.

"You hate to pull out," he said. "I'd be foolish to jeopardize the rest of my year. If I could rest three or four days and get everything back to normal . . . "

Clarence Rose withdrew from the tournament yesterday. He gave no reason. That decreased the field to 144.
