Aidan O'Brien sprint star Acapulco still in Royal Ascot picture

Having made a winning start to life with O'Brien earlier this month in a Listed race, O'Brien was keen to test her at a higher level before heading to Berkshire.

Winner of the Queen Mary in 2015 for Wesley Ward, Acapulco is in foal to champion sire Galileo.

O'Brien said: "Acapulco has a temperature but hopefully she will be all right to run at Royal Ascot."
