Brentford's poor away form continued with a two-nil defeat at League leaders Plymouth Argyle.
The team's arrival to Home Park was delayed in traffic caused by the huge crowd of just under eighteen thousand. The turning point was Leo Roget's dismissal by Referee Prosser, the tenth red card handed out by the man-in-black this season.
Brentford started robustly, Ben May forced Pilgrims' goalkeeper Luke McCormick into a fine save in the sixth minute, but the striker's effort from a Stephen Hunt free-kick was ruled out for offside. Plymouth upped the ante thereafter, streaming forward, with both Mickey Evans and Nathan Lowndes giving the Bees defence headaches.
Leo Roget was booked for encroachment at an Arygle free kick in the 21st minute, a decision that would have ramifications later in the half.
Four minutes before the break, Brentford were reduced to ten-men as Leo Roget was dismissed for a foul on David Friio. Moments later Matt Somner survived a penalty claim for handball, as The Bees went into half-time level.
Just at the two's side previous League encounter in March, The Bees fell behind within sixty seconds of the re-start, Tony Capaldi's shot bouncing off Smith's chest and into the net.
Thereafter, Plymouth took control, David Friio's shot was well saved by Smith in the 58th minute. Four minutes later Argyle doubled their lead. Paul Smith pushed out Evans' shot, but Nathan Lowndes shot gave The Bees goalkeeper no chance.
A Graham Coughlan header hit the post seven minutes later, with Evans missing a great chance seconds afterwards. Lowndes squared for Micky Evans, who shot wide from eight yards.
The Bees could not break down a stubborn defence, and to compound their misery, Stephen Evans was stretchered off late in the game with a leg injury.
