The Bees kept the same side that beat Bristol City in midweek for this Nationwide Division Two encounter against Oldham Athletic at Griffin Park.
The visitors had the first opportunity after seven minutes when Bees midfielder Kevin O'Connor misdirected a header straight to Carlo Corazzin in the box and his left-foot effort went well wide of the right-hand post.
On the quarter hour mark, Steve Hunt for the Bees saw his free-kick hit the wall and rebound to him, his left-foot effort went tamely wide of the target.
Matty Appleby for the visitors was yellow carded after 34 minutes for a trip on Hunt and a minute later Fitz Hall was also yellow carded for a foul on the same player.
Two minutes from the break the visitors almost took the lead when a cross from the right found Appleby unmarked in the box and his low goalbound strike was deflected off the line by Michael Dobson for a corner.
Six minutes after the break the visitors should have taken the lead when Appleby put Corazzin clear in the box and with only the Bees keeper to beat his low right-foot strike was saved by Paul Smith's outstretched legs.
On the hour mark the visitors were reduced to ten men when Hall was red carded for his second bookable offence. The Bees made a couple of late substitutions, they huffed and puffed but could not get the vital breakthrough. This young side can be proud of the progress they have made so far.
After the match, Brentford manager Wally Downes said, "the conditions were very hard out there, they performed to a level I didn't think we would so quickly, the lack of experience does not worry me, what they had in experience matched our enthusiasm."
