HALLANDALE BEACH, Fla. – Having undergone a change in running style and a change in rider since walking into the starting gate for the Grade 3 Holy Bull four weeks earlier, Simplification will try to prove a little change has done him a lot of good Saturday at Gulfstream in the Grade 2 Fountain of Youth, the major local prep for the $1 million Florida Derby on April 2. Simplification is the 5-2 morning-line favorite in a full field of 12 3-year-olds set to vie for a $400,000 purse and 85 Kentucky Derby qualifying points.
