The latter success was for Karl Burke, who Costello linked up with in the autumn on 2015.
Explaining the switch of codes, Costello said: “Financially it’s better and for longevity of your career it’s better. Flat racing is worldwide and there is lesser chance of being broke up.
“Karl has lots of ammunition, the yard is always going forwards, he’s a good trainer and a good guy. You are always going to ride winners and hop on nice horses.”
