Casey beat Paul McElhinney on points in the final to claim the trophy and winner's cheque to the value of £32,000. McElhinney replaced Ricky Owen in the final after he was ruled out with a cut, as a wildcard.
'Who knows what the future holds?' Casey told Sky Sports after the fight, 'I might get a shot at the European title after winning Prizefighter. I'm very proud of everything I've done.'
Casey improved to 8-0 (5ko).
The Limerick based fighter was a replacement for Wayne McCullough, after the former WBC Bantamweight champion pulled out with a hand injury.
