Big Buck's has extended his winning streak to 15 races after a hard fought win in the Cleeve Hurdle at Cheltenham.

Starting the race as 1/4 favourite, the majority of people expected Paul Nicholls' legendary horse to record a routine race win.

However, Dynaste led by five lengths at one point and Ruby Walsh was forced to ask a big question of Big Buck's.

A trademark jump at the last saw Walsh ride him into the lead and complete his 15th straight win.

Nicholls said: "If we won today it was great, but if we lost I was the one who was going to get shot.

"He switches off in his races. Ruby said he was going to play it late today.

"He's such a class horse, he's get to the last, pricks his ears and goes."

Nicholls will be hoping for a simliar performance from Big Buck's in the World Hurdle at Cheltenham in March.
