Bahr booked her Oaks place with a victory in the Musidora Stakes at York yesterday that increased the possibility of fellow fellow and Godolphin stablemate Cape Verdi lining up for the Derby.

After a cosy success over the odds-on Midnight Line, who was conceding 2lb to her, Bahr became a best-priced 4-1 second favourite for the fillies' Classic. Although the Godolphin team immediately committed Bahr to the Oaks, options remain open for Cape Verdi, the One Thousand Guineas winner.

Racing manager Simon Crisford said a decision did not need to be made until May 30, the supplementary entry deadline for the colts' Classic.

Winning jockey Frankie Dettori indicated he would be hard-pressed to choose between Bahr, ''a little thing with a big engine'' who had been working ''like a bomb,'' and Cape Verdi if they were to oppose each other at Epsom. ''They both worked together in the trial in Dubai and Cape Verdi beat her by about two-and-a-half lengths.''
