Justify is the early 7-2 favorite for today’s 144th Run for the Roses that features a full field of 20 colts. Justify, along with undefeated Magnum Moon, didn’t race as 2-year-olds. They’ll be trying to disprove an old jinx: No horse since Apollo in 1882 has won without racing as a juvenile. History would be written if Ireland-based Mendelssohn pulls off a victory. No European colt has ever won the Derby. The forecast calls for a chance of rain at various times today. Post time is 6:46 p.m. ET.
