Quick Suzy provided trainer Gavin Cromwell and jockey Gary Carroll with their first Royal Ascot success in the Queen Mary Stakes.

Carroll delivered Quick Suzy from off the pace on the stands side to challenge favourite and eventual runner-up Twilight Gleaming a furlong out, stretching clear to win by a length and a quarter at 8-1 – with 50-1 outsider Cheerupsleepyjean almost another two lengths back in third.

County Meath trainer Cromwell is more often associated with success over jumps – including at Grade One level at the Cheltenham Festival – but is adept on the Flat, too.

Quick Suzy, a maiden winner at the Curragh last month and then a Group Three runner-up at Naas, has nonetheless broken new ground for the yard with her Group Two victory.
