Three-in-a-row hopefuls Galway provided the opposition, however, Tipp powered to 2–18 to 2–7 victory. It was O'Keeffe's sole All-Ireland medal in that grade. O'Keeffe subsequently joined the Tipperary under-21 team.
Tipp later reached the All-Ireland, however, O'Keeffe's side were defeated by Kilkenny. In 2011 O'Keeffe made his senior debut for Tipp in a National Hurling League game against Waterford. His first championship start came later that year against Cork.
A 7-19 to 0-19 trouncing of Waterford in the subsequent provincial decider gave O'Keeffe his first Munster medal. For the third successive year, Tipperary faced off against Kilkenny in the All-Ireland final, however, on this occasion Kilkenny were slight underdogs going up against the new champions.
