Treadwell causes 33-1 upset in Ascot

Grand National-winning jockey Liam Treadwell returned to the big time with his most high-profile success since Aintree as The Last Derby caused a 33-1 upset in Ascot's United House Gold Cup.

The Irish raider's shock success acutely demonstrated the emotional highs and lows of National Hunt racing with trainer Eoin Griffin's first runner at the track, Sanglote, suffering a fatal fall in the previous race.
