Gun Runner, the Risen Star winner, and Mo Tom, who finished a troubled third in the race, both have been lowered to 15-1 on Watchmaker’s line after being 20-1 a week ago. :: DERBY WATCH: Top 20 list | McLaughlin playing game on global scale WHO’S NOT Airoforce, who had been the co-fourth choice at 12-1 a week ago, was dropped from the list following his poor performance in the Risen Star. :: ROAD TO THE KENTUCKY DERBY: Prep races, point standings, replays ON THE BUBBLE Fellowship could leap onto the list with a strong performance Saturday in the Fountain of Youth.
