Australian speedster Asfoora returned to her brilliant best to win a thrilling Group One Nunthorpe Stakes (1,000m) at York on Friday.

The 17-runner dash was wide open on paper, but Henry Dwyer’s mare turned the race into a procession under Oisin Murphy to win her second top-level race in Britain.

Asfoora always travelled ominously well just behind the leaders and, when others were rowing away, Murphy was just gently coaxing his mount along and the writing was quickly on the wall.

She took up the lead with 200m to go and sauntered away from her rivals, with rank outsider Ain’t Nobody storming home from the rear to finish second ahead of Frost At Dawn.
