Former Barnet trialist Francis Laurent hit a late winner for Southend United at Underhill last night.
Laurent, who was on trial for the Bees last summer, struck in the 86th minute.
It was Barnet's first defeat of the pre-season campaign.
Manager Ian Hendon again used the game to experiment. Yannick Bolasie continued in the centre of midfield, with the two Alberts - Adomah and trialist Jarrett on the wings.
New signing Daniel Leach again played in the centre of defence and performed well once more.
The Bees are also in action tonight, when they make the trip to Billericay Town.
They complete their pre-season schedule with a trip to Ebbsfleet on Saturday.
