Tatters to Riches, who finished sixth in the Grade 1 Del Mar Futurity on Sept. 4, is out of training after undergoing recent surgery to have a bone chip removed from a hind ankle. Tim Cohen, who owns Tatters to Riches with his father, Jed, said the colt will be rested for about four months before resuming training with Jeff Mullins. “We fully expect him back at the end of the year or the beginning of next year,” Cohen said. “The horse will tell us the next move.” Mullins said Thursday that Tatters to Riches will be based at his stable for a short time while recovering from the operation. Purchased for $1 million at the Ocala Breeders’ Sales Co.’s auction of 2-year-olds in training in April, Tatters to Riches won his debut by 1 1/4 lengths in a six-furlong race. In the Del Mar Futurity at seven furlongs, Tatters to Riches was as close as fourth but faded in the stretch to finish 10 1/2 lengths behind Bolt d’Oro. The Cohens will have Itsinthepost in the Grade 2 John Henry Turf Championship next Sunday on opening weekend of the Santa Anita meeting. A winner of two Grade 2 stakes, Itsinthepost was a troubled second in the Grade 2 Del Mar Handicap on Aug. 19.
