Arbroath boss Allan Moore kept his players locked in the dressing room for 45 minutes after tasting defeat at Bayview as he looked for answers to their indifferent 2015 form.
Moore’s men were unable to build on last week’s win over Clyde, their only victory this year, and went down to goals either side of the break.
The Methil men themselves went into the game under some pressure having tasted two defeats in a row, with things getting incredibly tight in the scrap for fourth spot.
It’s a position the Fifers hold and they showed they are in no mood for giving it up as they handed out a beating to the visitors.
The home side started well, with Allan Walker’s header from a Naysmith free kick clearing the bar by a matter of inches.
Arbroath, the early season pacesetters, now find themselves well adrift of top spot in third place.
However, with the likes of Bobby Linn and Simon Murray in the team, they are always capable of causing problems.
Murray shaved the post with a drive but, apart from that, the East Fife defenders will be pleased with their work in keeping the on-loan Dundee United forward quiet.
The Fifers were gifted a great chance to take the lead mid-way through the first half when Marc McCallum tripped Ross Brown inside the box.
With Brown turning away from goal, referee Mike Roncone flashed only a yellow at the ‘keeper.
But he made amends for his error by guessing the correct way from Derek Riordan’s penalty kick.
East Fife kept up their attack on the Arbroath goal and were rewarded on the stroke of half-time.
Brown again was fouled, this time on the edge of the box by Kevin Nicoll. Riordan this time made no mistake from his set-piece by wrong footing McCallum and placing his effort into the bottom corner.
As you’d expect, Arbroath started the second half with some impetus and tried to get themselves level.
In truth they could easily have been 2-1 ahead by 80 minutes.
Mark Whatley was twice guilty of passing up great chances to hit the net. And the Fifers punished them in the closing moments as they wrapped up a crucial win. Alan Cook created space for himself on the wing before crossing to Caolan McAleer who made it 2-0.
Arbroath assistant Todd Lumsden said: “We could have won a game of football on the chances we created.
“But it’s about putting the ball in the back of the net and again we’ve not done that and been hit with a suckerpunch with the free-kick.The second half we were pretty decent but then for their second goal we don’t deal with a ball in the corner, let the boy sneak between two defenders and get a cross over.
“That’s the way things have been going for us. We thought we’d turned the corner after the Clyde game but the first goal in games in this division is vital and we’re giving ourselves a mountain to climb.”
