SAM SPINNER announced himself on the big stage with an all-the-way win in the JLT Reve De Sivola Long Walk Hurdle at Ascot.

Winner of a handicap at Haydock last time out, the five-year-old stepped up markedly in class for Leyburn trainer Jedd O'Keeffe and the well-backed northern raider duly fended off all-comers in the hands of Joe Colliver.

Two big leaps at the last two flights meant Colliver was able to keep the revs up on the 9-2 winner, and L'Ami Serge, the last to challenge having travelled up strongly on the bridle, could never quite get on terms.

Unowhatimeanharry, the 6-4 favourite, was third.
