Kieran Callaghan rode his fourth career winner and second for Willie Mullins when Tenzing took the opening Coolagown Stud Maiden Hurdle at Cork.

The five-year-old gelding was making his first start over hurdles but appreciated the test of stamina as he got the better of a prolonged battle with second placed Roped In

The son of Milan had shaped as though wanting further when placed in his bumpers and the extra distance saw him in a much better light here. Friends N Commerce finished third, with favourite Fameaftertheglory back in fourth.

The winning rider said; "he was up in trip today and it really suited him. He had a look at the first two hurdles and after that got into a great rhythm and went away nicely from the second last. If something came to him he would have gone away again.

"I had loads of horse left and the step up in trip definitely suited him.

"I've been with Willie full-time for three years."
