Guineas Winners In Coronation Clash Pam Sly's 1000 Guineas heroine Speciosa and Nightime, winner of the Irish equivalent, are set for a fascinating clash in the Coronation Stakes at Royal Ascot tomorrow.Sly's flying filly acquitted herself well when fourth in the Oaks despite failing to stay the extra distance, and is sure to be well supported now she returns to a mile in the 15-runner event.Seven of her vanquished Newmarket foes renew rivalry, including Nasheej and Silca's Sister, who finished third and fourth in the 1000 Guineas respectively as well as Wake Up Maggie (fifth), Flashy Wings (11th), Nannina (12th) and Donna Blini (last).Dermot Weld's Nightime will be bidding to follow up her impressive success at the Curragh and will be joined by the Aidan O'Brien-trained Race For The Stars, who finished eighth in the English Guineas and fourth in the Irish.European interest is ensured by the presence of Price Tag and Lolita, both winners of their native 1000 Guineas ? French and German respectively ? although the former was demoted to third following a stewards' inquiry.Mostaqeleh, Nantyglo, Rajeem and the Jeremy Noseda-trained Vague complete the line-up.(C) PA Sport
