Winter faces six rivals in Coronation Stakes Dual Classic heroine Winter is the stand-out contender in the Coronation Stakes at Royal Ascot on Friday. The Aidan O'Brien-trained filly has already won the English and Irish Guineas and has scared off a good chunk of the opposition in the Group One over a mile. Just six other horses have been declared for the Coronation Stakes, two of which being Winter's stablemates Hydrangea and Roly Poly. Precieuse, trained by Fabrice Chappet, was supplemented for the race after winning the French 1000 Guineas. John Gosden has declared Dabyah, who looked really smart on her return to action at Newbury in April. North American trainer Mark Casse gives La Coronel the chance to shine, with Roger Varian represented by the in-form Tomyris.
