A Gavin Tomlin brace helped Southend United secure a comfortable victory at AFC Wimbledon.
The Dons could have taken an early lead when Jake Reeves struck the bar from 25 yards out.
But Tomlin lashed home to put the Shrimpers ahead before Ryan Cresswell headed home for 2-0.
Tomlin, who also got two at Torquay on Saturday, then headed in Kevan Hurst's free-kick and Barry Corr hammered home to compound the hosts' misery.
VIEW FROM THE DRESSING ROOM
Southend United manager Paul Sturrock told BBC Essex:
"I'm very disappointed with the first half, we definitely looked a bit sluggish and tired and sore.
"Second half, we got our second goal and we kicked on from there, I was very pleased with the general performance.
"We seemed to get more room (in the second half), the two strikers started to develop our game.
"We've worked very hard on our set pieces so we're very pleased we got some goals from them tonight."
