Jack Mitchell Beaten On Another FAV

I am at a loss to know why so many trainers stick him on their horses. Any jockey that needs to change his reigns 3 times inside the final furlong is obviously doing something wrong. Getting beat on Olympic Odyssey at 1/2 and Kawasir at 4/9 this week alone and then losing on Mordin at Ayr. Punters can afford to let his winners pass, like Joe Fannee..........a liability !
