Dewsbury Rams produced a magnificent effort as they went close to ending Leigh’s unbeaten Championship record before slipping to a 32-28 defeat.
The Rams felt aggrieved as they were denied chance to launch a last minute attack after full-back Greg McNally appeared to fumble a kick in front of his own posts.
It was a pulsating game, in which Dewsbury provided Leigh’s toughest test of the season so far.
The Rams led 6-0 early on following a Kieran Hyde penalty and Rob Spicer try but Leigh hit a purple patch, scoring three tries in the space of 10 minutes as winger Liam Kay bagged a brace and McNally also crossed, all converted by Martyn Ridyard.
Ridyard intercepted a pass and raced 60 metres to the line but Karl Pryce scored at the other end and Dewsbury trailed 22-10 at half-time.
Dalton Grant added an early second half try for the Rams, superbly goaled by Brett Seymour, but Leigh hit back with a Greg Worthington replied with a try for Leigh, converted by Ridyard.
Luke Adamson stormed over as the Rams again back but Kay looked to have sealed the points with his hat-trick try for Leigh.
Grant set up a grandtstand finish with his second try, superbly converted by Seymour but the Rams fell agonisingly short.
