GEORGE WASHINGTON is 2-1 favourite with the sponsors to give Aidan O’Brien a fourth triumph in the Stan James 2000 Guineas at Newmarket on Saturday.

Silca’s Sister, Opera Cape and Palace Episode, three of Godolphin’s high-profile acquisitions last autumn, all came out on top in their respective racecourse gallops on the Nad Al Sheba grass today.

George Washington has been installed the 4-6 favourite by Cashmans for the Darley Dewhurst Stakes at Newmarket tomorrow.

Aidan O’Brien tightened his grip on the betting for the Classics with a Group One double thanks to Horatio Nelson and Rumplestiltskin at Longchamp.
