After a seven-year hiatus Cork's hurlers claimed the provincial title in 1999. A 1-15 to 0-14 defeat of three-in-a-row hopefuls Clare gave Corcoran his second Munster medal in that code. Cork later faced Kilkenny in the All-Ireland decider on 12 September 1999. In a dour contest played on a wet day, Cork trailed by 0-5 to 0-4 after a low-scoring first half. Kilkenny increased the pace after the interval, pulling into a four-point lead. Cork moved up a gear and through Joe Deane, Ben O'Connor and Seánie McGrath Cork scored five unanswered points. Kilkenny could only manage one more score – a point from a Henry Shefflin free – and Cork held out to win by 0-13 to 0-12. It was Corcoran's first All-Ireland medal. He later won his second All-Star before claiming two Hurler of the Year titles.
