Joel Cooper and Matthew Shevlin inspired a superb second-half comeback as Coleraine claimed a massive 3-2 win at Larne.
The Bannsiders looked to be heading to defeat after a lacklustre 50 minutes saw them trail to James Simpson's excellent double.
But the Bannsiders' star men produced when they needed most as Cooper pulled one back on the hour mark before Shevlin levelled matters nine minutes later.
It was anyone's game after that and Cooper proved to be the match-winner yet again when he fired home in the 81st minute to secure the points for his side against the reigning champions, who slip to their first league defeat of the season.
It was a cagey opening 10 minutes with both sides vying for space. Unsurprisingly it was Will Patching who managed to find an opening as he released Joe Thomson, but the former Larne man's attempted pass into the unmarked Cooper was cut out by Matt Ridley.
Coleraine were nearly architects of their own downfall in the 14th minute as Lyndon Kane's wayward throw went straight to Paul O'Neill, who forced Lewis Webb into a good save with a low drive.
Larne weren't to be denied though as they broke the deadlock two minutes later with a sublime move which cut open the Bannsiders. Dan Bent's long ball picked out the run of Tomas Cosgrove, who exchanged passes with O'Neill, drawing Webb out of his goal before laying it on a plate for Simpson to fire into an empty net.
The Bannsiders responded as Patching drilled a free-kick straight into the palms of Rohan Ferguson while at the other end Dylan Sloan curled a teasing ball across the face of the visitors goal, which was just begging to be tapped home.
