Morley Street won his biggest prize to date as he beat the Jonathan E. Sheppard-trained Summer Colony by eleven lengths.
Morley Street's five-race winning streak came to an end at Ascot in December when he was beaten by Remittance Man in the Noel Novices' Chase after repeatedly jumping to the left on a right-handed course.
