Cracker off the mark in opener Mr Cracker justified his short price in the opening maiden hurdle at Navan with a cosy victory. Davy Russell's mount cut out the running and always looked in command down the straight. The even-money favourite was ridden out before the last to secure a three-and-a-half length victory over Ad Idem. "He's a nice horse and will be better on better ground," said winning trainer Michael Hourigan. "Davy said he had a leg in every parish and was snapping at his jumps. He might be a nice horse some day. "I would say chasing will be his game. He's a horse to look forward to. He promised a lot and is only starting to deliver now. He had a few hiccups on the way. "He was a free horse but he's not like that anymore. He's only five and is learning a lot."
