A goal from Killian McIntyre inside 16 seconds set the tone for Carrig, who led 1-7 to 0-3 at half-time, and the second-half carried an air of inevitability, the lead extending to 1-12 to 0-4 before a late Gary Farrell goal gave the Innishannon side some consolation.
McIntyre finished with 1-4 and was a constant threat to the Rovers defence, centre-forward David Drake conducting matters while Kevin Kavanagh was impressive at midfield. In contrast, Valleys found it difficult, the forward division struggling to make inroads.
A pair of Drake points following McIntyre’s goal gave Carrig a nice cushion, but two from Valleys’ Gary Farrell seemed to suggest they would challenge. Instead, four in a row by Carrig had them seven clear before John Cottrell got Rovers’ first score from play in the 26th minute, Stephen Gorman answering before half-time.
Carrigaline goalkeeper Seán Mellett made a good save from Farrell in the 32nd minute and two points from McIntyre and one by Drake extended the lead further, 1-10 to 0-3, prior to Cottrell’s second, a wonderful long-range point.
It was one of the few bright spots for them, however, as Carrigaline never relented, forcing numerous turnovers. Kavanagh and McIntyre got good late points, aided by Drake, to leave 11 points in it before Farrell’s goal, Gorman rounding things off in injury time with a wonderful outside-of-the-boot score for Carrig.
