Two&#45;time Horse of the Year Curlin, who had already established himself as a prominent source of classic stamina, put another feather in his cap last Saturday with Kentucky Derby runner&#45;up Exaggerator. Curlin, a son of Smart Strike, has been represented by a classic winner or classic&#45;placed runner from each of his first four crops. After siring 2013 Belmont Stakes winner Palace Malice, he followed up with 2014 Preakness Stakes runner&#45;up Ride On Curlin and 2015 Belmont third&#45;place finisher Keen Ice, who later defeated Triple Crown winner American Pharoah in the Travers Stakes. Exaggerator came into the Derby off a runaway victory in the Santa Anita Derby. In addition to Exaggerator, Curlin was represented on the weekend by four winners, including Curalina, who romped in the Grade 1 La Troienne Stakes on Friday at Churchill Downs. Curlin moved to Hill &lsquo;n&rsquo; Dale Farm in Lexington, Ky., for the 2016 breeding season. He is standing for $100,000.
