NEW ORLEANS – As the Fair Grounds assistant to trainer Mike Maker, Joe Sharp went down the Kentucky Derby trail in 2014 with Louisiana Derby winner Vicar’s In Trouble. Later that year, Sharp went out on his own, and now, as a head trainer, Sharp has a Triple Crown prospect in his own stable, Girvin, who was a two-length winner of the Grade 2, $400,000 Risen Star Stakes on Saturday at Fair Grounds.
