Although neither man is entered in this week's Kemper Open at Congressional, Hal Sutton and Don Pooley, the top two finishers Sunday in the Memorial Tournament, were among a number of PGA Tour players at Washington Golf and Country Club yesterday for the Jonathan Coe Memorial Pro-Am.

David Ogrin, who will play the Kemper, won the pro-am on the Arlington layout with 66. Pooley was next at 68, followed by Kenny Knox and Howard Twitty (69), Morris Hatalsky (70), Mike Nicolette (71), David Peoples (73) and Loren Roberts (74).

Sutton lay three off the green on the par-4 opening hole. When he saw that one of his amateur companions was in position to make a net birdie on the hole, Sutton picked up. That meant he would have no exact score and could not win any individual prize, but Sutton went on to make six birdies.

Ogrin and amateurs Tom Williams, John McConnell and George McGrory were low team with net 56.

Davis Sezna, a restaurateur from Wilmington, Del., and Marty West of Rockville are the only two amateurs entered in the Kemper.

"There is a natural intimidation of playing with the best in the world," said Sezna, who won the Poor Robert's charity tournament at Woodmont to qualify for the Kemper. "I never tried so hard on the practice tee. It's just nice to be here. If I can get into a rhythm, I hope to play all right. What makes it a little easier is that I played college golf with some of these guys." Sezna played at Georgia, where Bill Kratzert, now a tour pro, was his roommate.

West, Gary Marlowe of Woodmont, University of Maryland golf coach Fred Funk and former Frederick, Md., resident Donnie Hammond played a practice round together yesterday, with Hammond shooting under par. Hammond, a fourth-year pro living in Daytona Beach, Fla., scored his first PGA Tour victory when he won the Bob Hope Classic and $108,000 in January.

For the first time in seven Kemper Opens, the field will be 147 golfers, not 156.

Glenn Tait, a PGA Tour official, said 143 players had committed to him by the Sunday deadline of a half-hour after completion of play of the Memorial Tournament in Dublin, Ohio. The final four spots will be determined in a qualifier today at Poolesville.

"You can't say that players don't like the tournament, because some of the best players in the world are here," Tait said. "They are all independent businessmen. I have no idea why the field is not full."

Pro Tom Mullinax of Greenville, S.C., used a metal driver with a woman's shaft and grip and drove the ball 341 yards to win the District 10 Golf Digest long-drive contest held at Congressional's first hole. Jeff Fick of Baltimore was second at 340, followed by Tim Hefner, of Wilmington, N.C., 334.73. The three advanced to the national final, Oct. 6-7 at the Pensacola (Fla.) Open.
