TWO defensive mistakes gifted Forest Green three points in a top of the table clash at the New Lawn this afternoon.
Elliot Frear had fired Rovers into a 37 minute lead, before Guthrie's own goal four minutes later.
And with the game heading for a draw, up popped James Norwood to break Town's hearts late on.
A back four of Carl Magnay, Shaun Pearson, Toto Nsiala and Gregor Robertson. In midfield, Nathan Arnold, Craig Disley, Craig Clay and Christian Jolley, with Lenell John-Lewis and Ollie Palmer leading the Town attack.
It had been a very even first half when Rovers took the lead.
A cross from Fleetwood was met by Guthrie whose initial shot was saved by McKeown, Town failed to get the ball away and Elliot Frear was there, just 12 yards out, to fire past the Town keeper.
But just four minutes later the Mariners were level thanks to a Kurtis Guthrie own goal.
It was Guthrie who had fouled Christian Jolley in the build up to the equaliser. Nathan Arnold's inswinging free-kick from the left was met powerfully by the head of the Rover's player and it flew past Sam Russell to hand the Mariners a deserved leveller.
The second half continued in the same vein with both sides carving out chances. Ollie Palmer's effort went just wide, Jon Parkin had rattled James McKeown's woodwork at the other end, and Parkin had another audacious saved by the Town keeper from 30 yards. But Ross Hannah had a great chance to give the Mariners the lead on 80 minutes. A great dummy by John-Lewis allowed the Town striker in on goal. Unfortunately the experienced Sam Russell got down well to deny the Town striker and deny him again from the rebound.
But on 84 minutes, substitute James Norwood, who just come on for the hosts, was put through on goal by a Town defensive error and he calmly finished past McKeown.
It was a frantic end to the game as Town threw bodies forward, but it wasn't to be and the Mariners succumbed to their first away defeat since September.
