John Gosden won this race in 2016 with Persuasive and boasts the leading contender for this years renewal in the form of Indigo Girl, given a further boost by the employment of Frankie Dettori in the saddle who has a staggering 37% strike rate here at Sandown across the last 3 seasons.
Indigo Girl took a huge step forward from her debut win at Yarmouth to land the Group 2 May Hill stakes (8f) at Doncaster on her second career start.
She subsequently took another step forward to finish a half length 2nd in Group 1 company in the Fillies Mile at Newmarket on soft, stand out form in this field.
The daughter of Dubawi went off as a well backed favourite last time out on her seasonal re-appearance for the Valiant stakes (8f) however ran keen in the early stages and was well beaten in the final furlong upon fast ground at Ascot.
She's entitled to improve and strip fitter with that run under her belt on her second run back this season and if replicating her 2yo form in this Group 3 contest, she looks to have clear leading claims.
John Gosden is in fantastic form of late with a 32% strike rate across the last 14 days whilst he has also accumulated the most prize money of any trainer at Sandown across the last 3 seasons, paying further dividends to his runners chances.
