Each day leading to Saturday's Preakness Stakes, we'll profile some of the horses who will bolt from the starting gate in the 132nd running of the second jewel in the Triple Crown. Today, we'll profile the two horses being entered by trainer Todd Pletcher, Circular Quay and King of the Roxy. Pletcher, despite winning successive Eclipse Awards as North America's leading trainer, has never won a Triple Crown race. Both horses are training at Belmont and will van to Baltimore tomorrow. Pletcher has had an entry in the Preakness just once before, in 2000.
