Owned by Tony Bloom, the son of Golden Horn previously ran on the flat for Ralph Beckett in England.

One of 11 representatives from Closutton in the 18-runner race, Poniros was only in sixth position as they approached the last hurdle in the straight.

East India Dock (5/4 favourite) took the lead into the final flight and was challenged by the Joe Donnelly-owned Lulamba, trained by Nicky Henderson.

Just as the James Owen-handled favourite looked to be heading for success, Poniros came with a strong drive from Jonjo O’Neill Jr to burst through for a neck win at the line.

Lulamba claimed the runner-up spot by three-quarters of a length from East India Dock under Sam Twiston-Davies, with Lady Vega Allen (14/1) and Paul Townend fourth, another length and three-quarters back.

The surprised winning handled, who had just trained the longest-priced winner in the history of the Triumph Hurdle, said:

“He’s by Golden Horn, who I think is going to make a very good sire over jumps. He’s the sort of horse you’re looking for. I didn’t expect that. Did Tony Bloom back him? If he did, it wasn’t on my advice! We were hoping he would run well and be a nice horse for next year, so he’s ahead of schedule.”
