The first organised baseball team in Ireland was the Tramore Sea Lions.^[5] The Sea Lions were a youth team in Tramore, County Waterford. The team was organised and coached by local businessman Clive Butterworth.^[6]

The success of the Tramore Sea Lions in the local community led to the creation of the Waterford Walruses, a team based in nearby Waterford City. In 1962, Clive Butterworth brought two United States Air Force baseball teams to Waterford for an exhibition game. The game was played on Waterford GAA grounds. Butterworth also brought baseball to Dublin in the early 1960s, bringing the total number of Irish baseball teams to three. Within a few years, Butterworth's declining health led to the end of organised baseball in Ireland for nearly three decades.^{[citation needed]}
