Henry Cecil takes the wraps off an established star and a potential star when Newmarket's Guineas meeting gets underway tomorrow.
The former champion trainer unleashes the Derby favourite Beat Hollow in the Green Ridge Stables Newmarket Stakes.
Then 35 minutes later it's the turn of the Oaks winner Ramruma who returns to action in the Sagitta Jockey Club Stakes.
Beat Hollow, the impressive winner of his only outing to date, runs in this Listed contest after being withdrawn from last Saturday's Thresher Classic Trial at Sandown Park.
Cecil had decided he did not want to risk Khaled Abdulla's colt in the testing ground on the Esher track.
The underfoot terrain is likely to be much more suitable on this occasion with the ground at Newmarket reported to be good on the 10-furlong straight and good to soft elsewhere.
Beat Hollow, quoted at 7-1 favourite by Ladbrokes for the Vodafone-sponsored Derby, faces just four rivals in tomorrow's 10-furlong contest, including his promising stablemate Sandmason.
Godolphin are represented by Entisar - the Dubai outfit's first runner of the year in Britain - and the field is completed by Akeed and Ethmaar.
Ramruma, who ended last season with honourable defeat in the St Leger, faces 10 opponents as she seeks to return to winning ways.
But she looks to have a stern test in the Group Two contest with her rivals including the Queen's Blueprint, Lucido and Yavana's Pace.
Diamond White heads the six runners for the other Listed race on the card, the Dahlia Stakes.
