NEW ORLEANS – Nehro, the 2011 Kentucky Derby runner-up, will be scratched from the New Orleans Handicap on Sunday after tying up following a Saturday morning training session, trainer Steve Asmussen confirmed Saturday night. “He got a little tight today when he trained,” Asmussen said. “I’m not going to run him unless he’s 100 percent.” Nehro made his first start since the 2011 Belmont Stakes here Feb. 25, easily winning a first-level allowance race. The 4-year-old Mineshaft colt, who was second in the Louisiana and Arkansas derbies, still is seeking his first stakes win.
