Saturday night fever hit Drogheda as a late, late JP Rooney point saw Louth pull off the shock of the championship so far with a 0-11 to 0-10 win over Roscommmon.
In an amazing back door battle experienced forward Rooney conjured up an injury time winner against all the odds. It looked like Louth had blown their big chance when they spurned a three-point lead after 36 minutes, allowing Roscommon to move two ahead with just three minutes remaining.
But in an exciting finale points from Paddy Matthews and Christy Grimes first drew the sides level before Rooney fisted over the winner to spark wild celebrations.
It was a tactically excellent first-half that set Louth on their way, promising so much early on. Mark Stanfield, an 11th hour addition to the lineup, was the target man alongside Shane Lennon and JP Rooney and the trio profited considerably from high ball in.
Paddy Keenan pointed for Louth after just 24 seconds to lay down a marker for the evening that the home side would be no pushovers. Ger Heneghan responded with a superb leveller for Roscommon and they were tied again at 0-2, 0-3 and 0-4 apiece by the quarter-hour mark.
It was now clear that Louth meant business despite their low pre-match billing and they duly charged ahead. First Lennon boomed over a fine point and then Clarke, with 0-3 for the half, closed out the scoring with a converted free to leave them 0-6 to 0-4 ahead at the break.
With the wind now at their back Louth could smell victory and a wonderful Clarke point from play put them 0-7 to 0-4 clear after the restart. In hindsight, Louth appeared to have shot their bolt not scoring again until Matthews hit the mark in the 61st minute.
At that stage Roscommon had forged ahead and a Karol Mannion point put them two clear at 0-10 to 0-8 ahead after 67 minutes. But Louth had one final kick, Matthews reducing the margin and sub Grimes drawing the scores level in the 70th minute.
And Rooney stole the show in the dying moments, fisting over from close range after Lennon's break and solo run played him in.
