Enthused and Khulan put their Classic credentials on the line in tomorrow`s Peugeot Lowther Stakes at York.
The pair currently share 14-1 second favouritism with William Hill for the Sagitta 1000 Guineas.
Enthused, trained by Sir Michael Stoute, has won two of her three starts this season, winning the Princess Margaret Stakes at Ascot last time in emphatic fashion.
And Khulan made an impressive winning debut at Newmarket last month for trainer John Dunlop, scoring by three and a half lengths with the second, third and fifth scoring subsequently.
A seven-runner field for the Group Two contest also includes Tim Easterby`s Queen Mary Stakes winner Romantic Myth, who is on a retrieval mission having been beaten when odds-on favourite for the Weatherbys Super Sprint last time.
The York card opens with the EBF Galtres Stakes where Luca Cumani bids to extend his remarkable record in the Listed contest with Metronome.
The Newmarket trainer has won eight of the last 10 renewals of the race, scoring with Innuendo last season.
And a strong field for the #40,000 Bradford & Bingley Rated Stakes (Showcase Handicap) includes Worthington Lincoln winner John Ferneley and Persiano, who captured the William Hill Mile at Goodwood last time.
