Leyton Orient claimed their first win in six matches as they beat Brentford to ease their relegation worries.
Kevin Lisbie scored his eighth goal of the season when he met Dean Cox's free-kick and headed the O's ahead.
The Bees had a chance to grab a quick equaliser but Niall McGinn had his close-range header well saved by Orient goalkeeper Paul Rachubka.
Cox was again involved in the second goal as his cross was flicked on by Ben Chorley and Jimmy Smith fired home.
VIEWS FROM THE DRESSING ROOM
Leyton Orient boss Russell Slade told BBC London 94.9:
"I'm relieved, we worked tirelessly to get the first win of 2012 and to get it against our local rivals was great.
"We felt at half-time we had the experience to see this one through.
"The first clean sheet in 10 games has pleased me more than anything today.
"We looked determined and to get the first goal today was key to the eventual outcome. The confidence has been there, but you need things to go your way."
Brentford boss Uwe Rosler told BBC London 94.9:
"In the first half we were very flat, in the second half not at all, but we went too low in tempo and did not have enough desire.
"In the second half we were in their half the whole time, but for me it's the first time I have had to question the desire of the team.
"I don't understand why we have not shown more hunger, or capitalise from our opportunities."
