HALLANDALE BEACH, Fla. - When you have a barn the size of Todd Pletcher's, one that in 2005 set a single-season record for purse earnings by a trainer, there is bound to be an embarrassment of riches. And now with this year's first major weekend of racing nearing in south Florida, Pletcher is taking aim at a number of stakes races on Saturday at Gulfstream Park, largely with horses that are the understudies to his stable's marquee names.
