Brentford Griffins scored a last minute penalty as they came from 2-0 down to beat Tooting and Mitcham 3-2 in their latest Football Conference London/South East Division fixture.
The Griffins looked beaten as they fell behind away in South London to the Isthmian League Division One side.
However Ahren Vassell halved the arrears before Christie Pattison levelled matters in the second-half.
The hosts were then reduced to ten men before Bilal Aalouache scored the decisive goal from the spot in the last minute.
That result moves The Griffins up to fifth in the table ten points behind second-placed Boreham Wood Whites but with three matches in hand.
The Griffins have won six of their last seven matches and next week face matches at home to Woking Whites on Monday and away at Wealdstone on Wednesday.
Brentford Bees were on the reverse end of a last minute goal as they lost 1-0 at home to Southampton (Sparhsolt) on Wednesday.
The Bees defended resolutely all match but eventually their resistance was broken as The Saints netted in the last minute.
The defeat leaves The Bees seventh in the table and next up for them in the Home Counties/South West Division is a trip to Oxford United next Wednesday.
