If you are looking for an example of a dramatic impact from a substitute it doesn't get much better than Billy Byrne in the Leinster Hurling final.
At half time in the Leinster Hurling Final the All Ireland champions Wexford found themselves 0-05 to 1-07 behind Kilkenny. With only seven minutes remaining in the game Wexford were a point ahead and the game was there for either side.
Enter Billy Byrne. The veteran forward's first act was to kick the ball to the back of the Kilkenny net after a Liam Dunne free dropped short leaving the score Wexford 2-12 to Kilkenny 1-11.
Kilkenny's Charlie Carter twice went close to scoring a goal bringing out one brilliant save from Damien Fitzhenry. But it was Billy Byrne who had the final say scoring two more points as Wexford retained the Bob O'Keefe cup.
The final score was Wexford 2-14 Kilkenny 1-11
