Young Kenny heads the list of 39 entries confirmed today for the £70,000 Ladbroke Casinos Scottish Grand National on Saturday.
Peter Beaumont's charge is one of three runners in Saturday's Martell Grand National at Aintree who have stood their ground for the Ayr contest along with Red Marauder and Earthmover.
Young Kenny, who won the race last year, will head the handicap on 11st 10lb following the defection of another Aintree runner The Last Fling, the weights rising by 1lb.
Coral Welsh National winner Edmond, who missed Aintree because of unsuitable going, could take his place in the Ayr line-up.
A spokeswoman for trainer Henry Daly said: "Edmond will run on Saturday if the ground is soft."
Nicky Henderson's Marlborough, winner of the William Hill National Hunt Handicap Chase at Cheltenham, has been confirmed for the race.
Other notable possible runners include progressive novice Paris Pike, Christie's Foxhunter Chase winner Cavalero and Agfa Diamond Chase victor Trouble Ahead.
However, trainer Nigel Twiston-Davies, winner of this race with Captain Dibble in 1992 and Earth Summit in 1994, has withdrawn his smart novices Beau and King's Road.
Barry Simpson, racing manager to Marlborough's owner Robert Ogden, reported the gelding to be on course for Ayr.
However, the Whitbread Gold Cup at Sandown on April 29th remains an alternative for the eight-year-old.
Simpson said: "He's been confirmed and he's on course for the race.
"This is one of the races we had planned for him but he's also in the Whitbread as well.
"His participation really depends on two factors - looking at the opposition and the ground conditions.
"Any rain wouldn't do us any harm but he goes on any ground, he's won on heavy and he's won on good to firm. Ideally we'd want good ground.
"He hasn't tried the distance (four miles, one furlong) before but I don't think there'll be a problem with the trip."
