Signed from non-league Havant & Waterlooville last autumn, Fogden picked up a loose ball on the right of midfield and cut inside to unleash a terrific left-footed shot into the top corner in Tuesday night’s League One clash at Dean Court.
Fogden’s third goal of the season gave Bournemouth their first triumph since early February when they beat Exeter 2-0.
Bournemouth deserved to win a poor-quality affair between two out-of-sort teams and ought to have scored before Fogden’s eventual winner.
Harry Forrester’s headed goalline clearance denied Steve Cook a goal, Shaun MacDonald had a stinging shot saved and Wes Thomas hooked a shot wide.
Brentford, who suffered a fourth defeat in five matches, wasted one golden chance early in the second half when Niall McGinn shot wide of a gaping goal after Simon Francis had halted Forrester’s surging run.
