John Velazquez rode To Honor and Serve to a victory in last year’s Remsen Stakes, and will be aboard the top Kentucky Derby prospect when he makes his 3-year-old debut later this month in the $400,000 Fountain of Youth Stakes at Gulfstream Park, trainer Bill Mott said on Thursday. Velazquez is also the regular rider of Uncle Mo, last year’s champion 2-year-old male.
