Dubai: Trainer John Gosden’s dominance of the Group 3 Musidora Stakes, a leading trial for the Group 1 Epsom Oaks, continued unabated when the iconic Newmarket handler saddled his fourth winner of the contest in five six runnings with the ever-so-promising So Mi Dar.

Having pulled off a training coup when his filly upstaged her male rivals in the Derby Trial at Epsom last month, Gosden gave So Mi Dar the option of competing against her own sex in a strong renewal of the 2,000-metre contest which has produced six subsequent winners of the Oaks.

If So Mi Dar impressed at Epsom, she looked even more imposing in the hands of Frankie Dettori when coasting home a four length winner over Fireglow, the mount of Godolphin pilot William Buick, who fought out the minor placings with the Saeed Bin Surour-trained Promising Run and Mick Channon’s Harlequeen.

Fireglow, who was fourth in the 1,000 Guineas (G1) behind Minding, ran in the colours of Shaikh Hamdan Bin Mohammad Bin Rashid Al Maktoum, Crown Prince of Dubai.

A daughter of the high-class Da Re Mi, musician John Lloyd Webber’s multiple Group 1 winning filly, she extended her unbeaten record to three wins and is now the 5/2 second favourite for the Epsom Oaks on June 3.

Dettori, who was completing a York double having earlier won the Duke Of York Clipper Logistics Stakes aboard Magical Memory, said: “She’ll give me a good spin around Epsom.

“She’s got what you require (for the Oaks) — she’s got tactical speed, she travels, quickens and stays the distance.

“Now it’s up to Minding (hot Oaks favourite). She’s got to step up in distance — she’s very good — but I’ve got a good one, also.”

Sky Bet’s spokesman Michael Shinners told the Sportinglife: “The Derby picture may remain a little cloudy but it couldn’t be more different in the Oaks, with two high-class fillies set to go head-to-head.

“In any other year, that exceptional performance from So Mi Dar might’ve seen us cut her to a very short price but in Minding, she will face the sternest test of her career. The Oaks is a race to look forward to.”
