A strike in the 28th minute from Andre Gray has given Brentford a 1-0 half-time lead against Cardiff City at Griffin Park.
The visitors threatened early on when Federico Macheda beat the challenge of Moses Odubajo before firing a vicious effort towards the top corner, which forced David Button into a good stop.
The Bees worked the ball well across the pitch to present a chance to Alex Pritchard from distance, but his strike flew past the post without testing Simon Moore.
Cardiff carved out an opening for Craig Noone as Macheda did well to tee him up just outside the box, but his effort went inches wide as Button scrambled across his line.
Brentford took the lead when Pritchard struck a powerful free kick from distance which Moore could only parry, and Gray pounced on the rebound to fire into the back of the net.
