Gun Runner moved from No. 5 to No. 3 in the Ultimate Kentucky Derby Poll presented by Brisnet.com with his 4 1/2-length victory over 30-1 shot Tom’s Ready in Saturday’s $1 million TwinSpires.com Louisiana Derby at the Fair Grounds. Unbeatens Mohaymen and Nyquist, who meet in this Saturday’s Florida Derby at Gulfstream Park, remain entrenched in the top two spots, with Mohaymen getting 10 first-place votes and Nyquist two among the panel of 13 noted handicappers, turf journalists and analysts. However, turf writer Jennie Rees promoted Gun Runner, who is now 4 for 5 in his career, to first after having him in No. 2 since the poll’s beginning.
