JOHN Gosden has a genuine Derby contender in Christophermarlowe, who forged clear for Frankie Dettori to win Wednesday’s 10-furlong Investec Derby Trial by four lengths from Future Empire.

The Tapit colt, owned by Michael Tabor and Gosden’s wife Rachel Hood, had won here as a juvenile and was sent off at 4/6. He may not have beaten a great deal but clearly handles the course and returned a very respectable time after leading three furlongs from home.
