A second-half splurge of seven unanswered points helped Waterford IT dispose of IT Carlow in Carriganore.
Pauric Mahony and Jake Dillon let loose after the break, firing over 11 points. Between the posts, Stephen O'Keeffe stopped a rasper from Joe Carroll, while Stephen Maher excelled for the visitors. The Laois ace hit 0-5 in each half.
The sides were inseparable during an opening period that WIT shaded by 0-13 to 1-9, with Eoin Murphy and Cathal Kenny to the fore. DJ Carey's Carlow side dismissed their underdog status. Maher earned a penalty on 18 minutes which Ian Byrne blasted over. Kevin Kelly got the Carlow goal. But seven points in the space of 10 minutes changed the game for Colm Bonnar's side, who meet DIT in the last eight.
