In March 2005, he avenged this loss by teaming with Raven to defeat Shane and Vinny. This victory was part of a winning streak over the end of March where O'Shaunessy wrestled twice a day on 24, 25, 26 – including an 11-man Rumble win – and 27 March with a standard tag match and a ten-man tag team match. This series of victories, aside from one loss by disqualification to Vain, put him to a good form for the one-day tournament held in County Kildare to crown the inaugural IWW International Heavyweight Champion. On 28 March, O'Shaunessy put an end to his main rivalries when he defeated Vinny and then Vain in the quarter and semi finals, respectively. He met Darren Burridge in the final match and won to become IWW's first champion, but had to compete again in an evening show in Dublin, defeating Burridge and Vinny once more in a tag match alongside Vain.
