A brace from Clayton Donaldson gave Brentford their first away win since November as they beat Preston North End at their historic Deepdale home.
The striker scored from the penalty spot in the first half and again after the break as Brentford built on Shaleum Logan's opener to take a 3-1 win.
Brentford started with Donaldson as the lone front man, Sam Saunders just behind and Logan on the right of midfield and Preston had no idea what to do about it.
The home back line was continually caught out with Donaldson running in behind and Logan seemed to have the freedom of Deepdale on the right.
Preston manager Graham Westley was forced in to a tactical substitution before half hour had elapsed, sacrificing central defender Daniel Devine, to try and keep them in the game.
But by that point Brentford were two up and although Paul Parry pulled one back for Preston, Donaldson added a third early in the second half and saw the game out comfortably.
The Bees went ahead just before the ten minute mark through Logan.
Saunders set Donaldson away, carving open the home defence, the striker took it early but the giant Thorsten Stuckmann palmed the shot away - the ball broke to Harry Forrester who lifted a delicious cross to the far post for Logan to arrive, completely untracked, and head in.
Donaldson almost doubled the lead moments later when Saunders again put him away but Stuckmann was quickly out and the striker's toe-poke was blocked.
Andy Procter volleyed over for the home side and Adam Thompson made a fantastic headed clearance to stop Graham Cummins heading in but they were porous at the back and Devine was culpable as Brentford went two up.
The central defender missed a clearance and Donaldson got in behind, the striker was hauled down by Devine as he tried to make amends and referee James Adcock pointed to the spot.
Donaldson took the kick himself and stroked it down the middle to double Brentford's advantage.
Chuks Aneke curled a shot over before Westley introduced Chris Holroyd for the hapless Devine and Preston improved.
The wide man had a shot blocked and then fired in an effort that cannoned away off the far post.
Toumani Diagouraga had a shot blocked and then flicked a header over from a Saunders corner as Brentford proved that although the home side were better going forward, they were still lacking in defence.
Donaldson could have put Brentford out of sight when he again got behind that back line but he miss-controlled and Stuckmann saved.
That proved to be a key moment as Preston were handed a lifeline moments later.
Holroyd headed down and Harlee Dean bundled Cummins over on the edge of the penalty area.
Mr Adcock again pointed to the spot and Parry slotted home low to Richard Lee's left.
Saunders curled a free kick just over the crossbar as Brentford sought to restore their two goal lead before the break.
They did not, however, have to wait long after the interval to do so.
Brentford took a short free kick and the influential Douglas lifted the ball in to the box, Donaldson arrived to head it powerfully past Stuckmann to give The Bees an advantage they never looked like losing.
Lee had to make a save at the feet of Cummins but Preston offered little by way of response.
Donaldson came close to completing his hat-trick with a flicked effort from a Jake Bidwell free kick that was blocked by the home defence.
As time ticked down Preston threw more long balls forward but they were largely meat and drink to Dean and Karleigh Osborne.
Douglas almost added a fourth for The Bees with a curling shot that was deflected wide and Niall McGinn had a shot blocked.
In truth, Brentford looked more like scoring than their hosts - McGinn went clear and shot over in stoppage time - and when Mr Adcock brought proceedings to a close, they were worthy winners.
