Butler's efforts give Tipp edge
Tipperary 0-16 Waterford 0-15
Tipperary needed extra-time to see off Waterford at Dungarvan as Ian Barnes and David Butler bagged five points apiece.
Waterford's John Hurney was dragged down for a penalty in the ninth minute but David Power dragged his effort left and wide.
Waterford were 0-6 to 0-4 up at half-time but the gap was closed to one point on 40 minutes, Tipperary leading 0-8 to 0-7.
The Premier finished strongly to force extra-time and Butler then shot three points for Tommy Toomey's charges to set up a provincial semi-final against Cork next month.
