Ray Floyd, the reigning U.S. Open champion, was unable to play in yesterday's 10-man Merrill Lynch Shootout because one of his children was ill at home in Florida.

Floyd is expected to play in today's Kemper Open pro-am and will play in the tournament proper, starting Thursday.

Floyd's replacement, Gil Morgan, lost the shootout on the ninth and final hole to Masters champion Larry Mize. Both parred the par-3 hole. To break the tie, both were required to hit out of a greenside bunker, the closest to the hole winning the $3,000 first prize. Morgan failed to get out of the trap with his swing, and Mize was the easy winner when he blasted his ball from the sand to within two feet of the cup. Morgan won $2,000.

Kemper Notes:

Andy Bean has withdrawn from the Kemper Open for the second straight year. Last year, Bean appeared at Congressional but injured his back practicing, could barely walk, and withdrew.

"I presume it's his back again," tournament chairman Ben Brundred said. Brundred said Bean withdrew late Monday night. . . .

Greg Norman, the defending Kemper champion, will try to uncork one of his huge drives on the second hole of today's pro-am, which starts at 7 a.m.

The professional with the longest drive at the 615-yard, par-5 wins $5,000 as part of the MCI long distance driving competition. Because of rainouts at Doral, Atlanta and Memorial, the purse has accumulated.

"I think Greg hits it as far as anyone except Davis Love," said Phil Blackmar, who has the most points in the season-long competition. The pro with the most points at the end of the season wins $50,000. Norman will tee off from the first tee in the pro-am at 11:45 this morning, Fred Couples at 12:39 p.m. and Lee Trevino at 12:48.

Floyd tees off on the 10th hole at 11:45. Former Kemper winners Bill Glasson (8:48 a.m.) and John Mahaffey (8:39) will also tee off on the back nine. Kemper Pro-Am pairings, C8
