DEL MAR, California &ndash; Two trainers, barring the unfortunate before Friday and Saturday, will have 13 runners in Breeders&rsquo; Cup races, the most of any horsemen this year. One of them, Chad Brown, is based in New York. The other goes about his business in Ireland.Aidan O&rsquo;Brien had 11 Breeders&rsquo; Cup runners in 2011 and 12 last year at Santa Anita, but the first Breeders&rsquo; Cup at Del Mar has brought out the largest shipment of O&rsquo;Brien runners yet. Fourteen in all were en route to California on Monday, with Declarationofpeace slated for the Juvenile Turf Sprint and the other 13 in Breeders&rsquo; Cup races.O&rsquo;Brien will have runners in the Classic, Turf, Mile, Filly and Mare Turf, Juvenile, Juvenile Turf, Juvenile Fillies Turf, and Turf Sprint. It will be a surprise if he does not win at least one race. O&rsquo;Brien already has set a record this year winning 26 Group 1 or Grade 1 races, surpassing the 25 Bobby Frankel won in 2003. And with 111 Breeders&rsquo; Cup starters going into this year&rsquo;s races, O&rsquo;Brien has run more horses in the Breeders&rsquo; Cup than any trainer save Wayne Lukas (164) and Todd Pletcher (128). The Breeders&rsquo; Cup refers to its races as World Championships, and Aidan O&rsquo;Brien, all by himself, is lending plenty of weight to that characterization.
