Knappers Hill (8-1) stayed on well in the closing stages to land the Grade Two Two Weatherbys hstallions.co.uk Standard Open National Hunt Flat Race.

The five-year-old, trained by Paul Nicholls, took his unbeaten record to three when scoring by half a length under Megan Nicholls. Peking Rose put in good late gains to fill second place, a length and a quarter ahead of the winner’s stablemate Stage Star

The winning rider said: “That was amazing — I’m on cloud nine. I can’t believe what has just happened. I spoke to Rachael (Blackmore) before I came out and she says she was shaking like a leaf and I feel like that now.

“It’s awesome. I’m delighted. Who would have thought I’d have been riding at this meeting? I had a great time pointing then turned to the Flat. I’m just so happy. Dad and the team have really helped and looked after me and when he mentioned about riding some of the bumper horses I was snapping his arm off. You can’t help but be excited riding young gorgeous horses like that.

“I know I’m babbling on, but I’m quite speechless at the same time. It’s awesome. Any bigger meeting whether it is over the Flat or jumps is huge. To be riding on Grand National day is like anyone’s dream. To have a winning chance, let alone be able to ride the winner is just amazing. It’s my first ride in a graded race.”

She added: “This horse has been fantastic. He was my first listed winner and he has now given me a graded winner. Mr Barber and Mr Vogt who own him have been huge supporters of the yard but me as well and to repay them is just incredible. My legs are going underneath me. I’m just ecstatic.”
