Kilkenny secured the Leinster crown again in 2008, with Delaney collecting a seventh winners' medal following a 5–21 to 0–17 drubbing of Wexford. On 8 September 2008 Kilkenny faced Waterford in the All-Ireland decider for the first time in forty-five years. In a disappointingly one-sided final, Kilkenny produced a near perfect seventy minutes as Waterford endured a nightmare afternoon. A 23-point winning margin, 3–24 from play, only two wides in the entire match and eight scorers in all with Eddie Brennan and Henry Shefflin leading the way in a 3–30 to 1–13 victory. It was Delaney's fourth All-Ireland medal, while a fourth All-Star quickly followed.
