Sheehan hit 1-4 yet it was the 1-1 he plundered in a devastating 60 seconds spell that provided his side with the platform for victory.
Sheehan put Glanworth 0-6 to 0-5 ahead by the 37th minute but following Michael Pierce’s neat lay-off the corner-forward goaled six minutes later and seconds after swung over a beauty to push Glanworth five clear, 1-7 to 0-5.
Cill na Martra’s Máirtín Ó Conchúir then had a shot saved by Thomas Fitzgibbon and crucially, excellent midfielder David Pyne extended Glanworth’s lead. An Ó Conchúir pointed free was all Cill na Martra, who hit 11 wides to Glanworth’s seven, could muster thereafter.
Glanworth began with intent as Sheehan, Pyne and Pierre O’Driscoll (free) had them 0-3 to no score ahead inside seven minutes.
Nollaig Ó Laoire became more prominent at centre-back for Cill na Martra while Seánachain Ó Loingsigh and Sean Ó Ceilleachair brought the deficit back to one. Still, Glanworth, with Pyne and Denis Healy commanding at midfield, were more fluid and Sheehan added their fourth point.
Ó Conchúir hit back scoring an outrageous 40-yard effort but Pierce restored Glanworth’s two-point buffer in the 26th minute (0-5 to 0-3).
Nearing half-time Glanworth had a goal chalked off before an Ó Conchúir free afterwards meant Cill na Martra trailed by just one at the interval, 0-5 to 0-4. Pyne’s lengthy punt deep into Cill na Martra’s full-back line was pounced on by Pierce – the attacker fisting to the net – but referee David Daly adjudged him to have fouled goalkeeper Eoin Ó Duinnín who then departed injured.
Two minutes into the second half Ó Ceilleachair’s initial goal-bound shot was stopped by Fitzgibbon and though he curled over from the rebound to level, Sheehan’s subsequent ruthlessness proved decisive.
