Brentford extended their unbeaten run to three with a derby victory over Leyton Orient.
Lewis Grabban, who signed on loan from Millwall on Thursday, scored the only goal of the afternoon late in the first half.
There was plenty of action in both penalty areas but clear cut chances were few and far between, with much of the play in the middle of the field.
The game was full of the hustle and bustle you expect from a London derby, with openings at both ends but little really good football.
Toumani Diagouraga dominated the early midfield battle and most of Brentford's attacking moves in the first quarter started with the big midfield man winning the ball in key areas.
Brentford had the best chance of the first half hour when the ever-dangerous Myles Weston swung over a fantastic cross from the left and Sam Saunders arrived to meet it four yards out, but he contrived to head it over.
And they took the lead just before the break when Saunders worked room for Kevin O'Connor to put the ball into the box, it was half cleared but Marcus Bean headed back and Grabban looped the ball over Jamie Jones and in off the post.
Leyton Orient defenders had been scrambling back to try and clear but on the advice of his assistant, referee Keith Stroud gave the goal.
Brentford probably just about deserved to be ahead but Orient had been dangerous when they went forward - Wojciech Szczesny had to make an early save from a James Scowcroft header and O'Connor made a fine tackle when it appeared Jonathan Tehoue was in behind.
Eric Lichaj was causing a few problems with his long throws and O'Connor made an important far post block from a Jason Demetriou effort.
At the other end, Charlie MacDonald had an early shot blocked and Tamika Mkandawire produced a goal-saving tackle when Diagouraga almost found the Bees' top scorer with a through ball.
Szczesny saved from a Scowcroft flicked header and again when the same player shot from the edge of the box while Pim Balkestein blocked a shot from Mkandawire.
The Os almost got back into it just before the break when a Sean Thornton free kick was blocked by Sam Wood and it looped up and landed on top of the net.
Brentford had chances to double their lead after the break - MacDonald headed a Saunders free kick wide and then saw a shot blocked by Ben Chorley - but Orient came out with renewed vigour.
They had a lot of the ball early in the second period and should have levelled just before the hour mark.
A ball over the top caught Brentford out and Adam Chambers nipped in behind Balkestein but Szczesny was quickly out and saved with his legs.
Brentford made a change just past the hour mark - introducing Ben Strevens and shifting Grabban to the right - and they were soon back on top.
Leon Legge powerfully headed a Grabban corner narrowly over and Strevens curled a shot wide when Chorley made a tackle to prevent MacDonald going through.
Grabban almost scored his second of the afternoon when he picked the ball up on the right and darted towards goal, a shot from the edge of the box was deflected and Jones had to tip it over at full stretch.
From the resulting corner Strevens headed straight at Jones as Brentford searched for the killer second.
They were almost hit with a sucker punch when Thornton's left footed effort from 18 yards faded narrowly wide of the far post.
MacDonald forced Jones into a fine save after a nice turn on the edge of the box and from the resulting corner, Balkestein saw a header deflected wide.
Thornton came close to snatching a leveller at the other end with a bobbling shot which Szczesny had to turn away low to his right.
Orient threw bodies forward searching for an equaliser but they could not find one and Brentford took the points.
