Inter-county
In 2006 Kearney made his senior championship debut for Waterford in an All-Ireland qualifier against Westmeath.
He later claimed a first Munster medal as Waterford defeated Limerick by 3-17 to 1-14 in the provincial decider. While Waterford were viewed as possibly going on and winning the All-Ireland title for the first time in almost half a century, Limerick ambushed Kearney"s side in the All-Ireland semi-final.
2008 began poorly for Waterford as the team lost their opening game to Clare as well as their manager Justin McCarthy. In spite of this poor start Kearney"s side reached the All-Ireland final for the first time in forty-five years.
Kilkenny provided the opposition and went on to trounce Waterford by 3-30 to 1-13 to claim a third All-Ireland title in-a-row.
In recent seasons Kearney has remained on the Waterford panel but has failed to make an impact on the starting fifteen.
