Kilcormac/Killoughey (Offaly) 2-13
Shelmaliers 0-18 (Wexford)
Cillian Kiely's late-gasp point in extra-time handed Kilcormac/Killoughey a dramatic win over Shelmaliers at Wexford Park.
Danny Owens' charges will now meet Raharney of Westmeath at Cusack Park in a fortnight's time for a place in the Leinster final as they bid to emulate their 2012 success.
Joe Kelly, who scored 2-7 as Shelmaliers' claimed their maiden Wexford SHC title at St. Anne's expense seven days ago, notched the home side's first four points, but they were rocked back on their heels when Conor Mahon's 18th minute goal helped the double Ks to a 1-4 to 0-5 lead.
Shels grabbed the next four points to regain the lead, but the visitors rallied to trail by the minimum at half-time, 1-6 to 0-10.
Killian Leonard had the sides level again early in the second half and there was little to separate them until Shels hit a late purple patch which yielded unanswered points from Tommy Barron, Eoin Doyle and Ciaran O'Shaughnessy.
However, James Gorman scored an injury-time goal to force extra-time, 2-9 to 0-15.
The sides scored three points each in the first period of extra-time before Kiely finally settled it with his fourth point right at the death.
