THE Blues left it to the last possible minute to clinch their third victory on the spin.
Barrington Belgrave came off the bench for fellow striker Graeme Jones and was on hand to tap in from three yards out from Leon Cort's knock down deep into stoppage time.
The win lifted the Shrimpers up to fifth in the Division Three standings, just two points off leaders Hartlepool, who face Bournemouth away later today.
