On Wednesday, the Newmarket-based trainers will be hoping that Emily Upjohn can enhance her Epsom Oaks credentials with victory on the Knavesmire in the Group 3 Tattersalls Musidora Stakes, a contest that has unearthed seven fillies who have done the Knavesmire/downs double.

The daughter of Sea The Stars has won both of her starts to date, including a nine-and-a-half length success in a fillies’ novice stakes at Sandown last month.

That triumph has resulted in her vying for Oaks favouritism with the Aidan O’Brien-trained Tuesday. But the richest ever renewal of the Tattersalls Musidora at £125,000 is sure to provide a far stiffer examination of Emily Upjohn’s Classic credentials.

Among her four rivals is the similarly unexposed Life Of Dreams – victorious on her debut at Newbury in April – and three other fillies who also all won on their last outing. But Emily Upjohn looks certain to head the market for tomorrow’s extended mile and a quarter race.

John Gosden said: “She is a big, rangy filly. She’s won her maiden and novice – and done it nicely. But now she’s moving up to a completely different grade, taking on other smart winners. We’ll learn an awful lot more about her (at York). She’s one of those fillies who will get better with age because she certainly has the scope and frame to do it.”

Stable-mate, Magisterial, will be sent on a similar fact-finding assignment when he contests Thursday’s Al Basti Equiworld Dubai Dante Stakes. The son of Frankel was one of nine colts that stood their ground at this morning’s 48-hour declaration stage.

He won on his second career start at Haydock last October before reappearing last month at Leicester where he made all to score by a length and half in a mile and a quarter novice race.

Now Epsom Derby entry Magisterial will seek to prove himself against a different level of competition, including the Sir Michael Stoute-trained Desert Crown and El Bodegon, handler James Ferguson’s first Group 1 winner.

John Gosden said: “He got the run of the race (at Leicester). This is the Dante – there’s always smart colts in there. And I think from that point of view, he deserves to take his chance – then we will know which way we want to go with him afterwards.”

The Dante Festival at York Racecourse runs from Wednesday 11 May to Friday 13 May inclusive. Tomorrow’s 1.50pm curtain-raiser is the Sky Bet Race To The Ebor Jorvik Handicap. For tickets please visit www.yorkracecourse.co.uk
