The first selection on the second day of the Cambridgeshire meeting comes in the Listed Rosemary Stakes over a mile and Zanbaq for Roger Varian makes big appeal.
Starting her career off last year in November she was an exciting winner of a 7f maiden at Kempton, seeing off Washraa for the same owners.
Saved for her three year old career she made her seasonal debut in April at Goodwood when third in the Listed Conqueror Fillies' Stakes over a mile but next time out back at 7f she got back to winning ways in a Fillies' Novice Stakes at Haydock.
Seen twice more since then she ran a cracker in the 28 runner Sandringham Stakes at Royal Ascot to finish a length second behind Heredia.
Bumped up into the Group Three Valiant Stakes over the same C&D when last seen she was below par back in fifth but having been kept fresh since then and having been well backed for this event, she can get back to her best.
