Pompey crashed out of the Carling Cup tonight to Barnet.
The League two side pulled off one of the upsets of the night to snatch a 1-0 win at Fratton Park and dump Steve Cotterill’s side out of the competition.
Lawrie Sanchez’s side only preserved their Football League status on the final day of the last campaign.
But they were good value for the win as Sanchez grabbed the bragging rights over his old Wimbledon pal Cotterill.
Bees captain Mark Hughes got the only goal of the game after 30 minutes after debut-making keeper Stephen Henderson had spilled a corner.
The ball was worked out to the excellent Mark Marshall and Hughes was there to head home his cross.
Izale McLeod had two one on ones saved and Clovis Kamdjo had a first-half header disallowed as the visitors ran the Blues ragged.
It was much the same after the break with Pompey failing to find any rhythm.
Greg Halford had a header from a corner midway through the half saved by Dean Brill.
Sub Charlie Taylor later had two good chances to add a second, though, with Barnet deserving victors and Pompey left to lick their wounds.
