Everything you need as the mighty Alpha Centauri goes for a fourth Group 1

She has been the shining light so far this season and Alpha Centauri bids for a fourth Group 1 of the year in the Haras du Fresnay-le-Buffard Jacques le Marois at Deauville.

Trained by Jessica Harrington for race sponsors the Niarchos family, Alpha Centauri takes on colts for the first time but is hot favourite to add to her victories in the Irish 1,000 Guineas, Coronation Stakes and Falmouth Stakes.

Winning the Group 1 Keeneland Phoenix Stakes has become common for Aidan O'Brien, who runs Sergei Prokoliev in a bid for a 17th success. Martyn Meade is hoping to derail that with Advertise.
