Trainer Mike Maker has three horses running in this year's Derby.
Vicar's In Trouble, General A Rod and Harry's Holiday are the ones Maker will put in the field of 19.
All the hard work throughout the year, each and every day, could pay off in a big way if today's Oaks winning jockey Rosie Napravnik, for example, rides No. 1 Vicar's In Trouble to the roses as well.
