Paul Sturrock again praised the versatility of Ryan Cresswell after his Southend side beat AFC Wimbledon 2-1 in the JPT.
The centre-back was pushed forward into attack for the final 11 minutes at Roots Hall and he responded by heading home an injury-time cross from substitute Neil Harris.
Gavin Tomlin had earlier scored his first Southend goal to cancel out Frankie Merrifield's opener.
The Shrimpers boss said: "Ryan knows what he's doing when we put him up there and he doesn't look out of place at all.
"He scored an equaliser for us at Northampton the other day and he's gone up there in this game and got the winner.
"He's a nuisance for opposing defenders and the success we have when he goes up there proves a point."
