A roar of approval went up from the gathering of media following the Breeders' Cup Classic when Tiznow's owner Michael Cooper announced that the son of Cee's Tizzy would race again next year. The announcement also brought a loud "whoop" from jockey Chris McCarron, who pumped his fist in the air."I mean he is a racehorse," Cooper said. "and there is plenty of time to do other things. If we can keep him sound and happy, he'll be a racehorse for another year."With his victory in the Classic, the homebred son of Cee's Tizzy has won eight of his 15 career starts for earnings of $6,427,830.On the other hand, Dr. John Chandler, manager for Juddmonte Farms, indicated Sunday that Jockey Club Gold Cup winner Aptitude, who finished eighth in the Classic after a very wide trip, most likely will be retired at the end of the year. "There's an outside chance we'll take a shot and race him, but the chances are we'll stick to our plan and retire him," Chandler said.
