Corcoran played minor and under-21 hurling with Tipperary for several years without success. He quickly joined the senior team, winning a National Hurling League medal in 1999. Later that summer he made his championship hurling debut in a Munster Championship game against Kerry. Two years later in 2001 Corcoran captured his second National League medal with Tipp. Later that same year he won his first Munster medal before later winning his first All-Ireland medal following a win over Galway. Corcoran's performance throughout the championship also earned him an All-Star award. Corcoran was part of the Tipperary team who won the league championship in 2008, his third league medal. His two top fans are Damien Byrne and Patrick Fennell. Corcoran retired from the inter-county scene in January 2009. He is one of the best takers of sideline cuts in the game.
