His rivals are expected to include Old Fashioned, Papa Clem, and Poltergeist. There are 79 nominees to the race.\nAin't He a Pistol heads Nodouble\nThere have been just two Arkansas-bred stakes run each year at Oaklawn since 1979, the familiar Rainbow and Rainbow Miss for 3-year-olds. But this season, the statebred stakes program has been expanded. Oaklawn will introduce a new race for older Arkansas-breds at six furlongs on Sunday when it runs the $50,000 Nodouble Breeders'. It will have a strong favorite in Ain't He a Pistol.\n"This is his big race," said Tom Howard, who trains Ain't He a Pistol. "Ever since we heard about it, we've kind of been waiting and pointing for it."\nAin't He a Pistol comes into the Nodouble off a neck allowance win against open company, covering six furlongs in 1:10.60. Since the race, the runner-up, Grand Sensation, has won a $65,000 optional claimer here with a Beyer of 95, and the sixth-place finisher, Sebastian County, has come back to win at the same level, with a Beyer of 99. Howard said he was looking for a good race from Ain't He a Pistol, but the win was a pleasant surprise in a deep field that included the Grade 1-placed Greeley's Conquest.\n"I thought we could be close in there, somewhere he'd account for himself, but he always seems to step up for the occasion," Howard said of the 14-time winner. "He's always willing and ready and he proved himself."\nPerry Compton has the mount on Ain't He a Pistol, who races for Lewis Matthews Jr. The stakes will share a card with the $50,000 Rainbow.\n* Unbridled Express, who finished second by a head in his first start in 2o1/2 years on Thursday, came out of the race well and will head next to Kentucky, said his trainer, Bernie Flint.\n* Jockey Tim Doocy, who is closing in on 5,000 career wins, was at 4,992 through Thursday.
