The concluding TRM Invest In Calphormin Maiden at the Curragh this afternoon was decided in the stewards room with Mr Everest getting promoted after finishing second past the post.

There was a dramatic finish to the mile-and-a-half contest with High Haven and Mr Everest fighting it out inside the final furlong.

High Haven drifted left under pressure, colliding with her rival, and got home by just a head at the line.

Not surprisingly a enquiry was called and the stewards deemed there was enough interference to reverse the placings of the first two home.

The Joseph O'Brien-trained Mr Everest, ridden by the trainer's brother Donnacha, was given the verdict on his debut over his fellow newcomer.

“He's a grand big horse. We didn't expect him to win but thought he would run well,” said winning trainer.

“He'll probably make a nice staying horse and he probably deserved to get it in the stewards room on the day.”
