Coroebus led home stablemate and hot favourite Native Trail to provide trainer Charlie Appleby with a one-two in the Qipco 2000 Guineas at Newmarket.
The Moulton Paddocks handler appeared to hold the ace hand in his bid for a first victory in the Rowley Mile Classic, with last season’s champion juvenile Native Trail the 5-4 favourite to keep his unbeaten record intact and Coroebus also prominent in the market at 5-1.
Native Trail proved his well-being with a comprehensive victory in the Craven Stakes two and a half weeks ago weeks ago, while Coroebus was making his first competitive appearance since winning the Autumn Stakes over the course and distance in early October.
With the pair drawn on opposite sides of the track, they raced wide apart for much of the straight-mile contest, with William Buick the first to get vigorous aboard Native Trail nearest the stands side.
James Doyle, on the other hand, was able to wait until the furlong marker to pop Coroebus the question and he found plenty racing out of the dip to prevail by three-quarters of a length.
Having been under a ride from an early stage, Aidan O’Brien’s Derby favourite Luxembourg made eyecatching late gains to finish best of the rest in third.
