Hermosa's odds for the Coronation Stakes were slashed on Wednesday afternoon, after it was confirmed she would skip the French Oaks in favour of accepting an invitation to the royal meeting at Ascot this month.

The Ballydoyle master also exclusively revealed that QIPCO 2,000 Guineas winner Magna Grecia, was found to have suffered a pulled hamstring when fifth in the Irish equivalent at the Curragh.
The St James's Palace Stakes and a rematch against Too Darn Hot and Phoenix Of Spain remains his number one priority.
O'Brien continued: "The hamstring issue only came to light when Magna Grecia went back cantering.
"We're hoping to run him in the St James's Palace but it will depend on whether he continues responding to treatment.
"We'll review things towards the end of next week."
