Southend moved up to second in League Two as they easily defeated Port Vale.
An unmarked Mark Phillips put the hosts in front when he headed in Ryan Hall's corner and Liam Dickinson made it 2-0 with a header from another Hall pass.
The Shrimpers were gifted a third when Peter Gilbert's cross was turned into his own net by Vale's Gareth Owen.
Vale's Marc Richards and Louis Dodds had shots saved by Glenn Morris and the visitors ended with 10 men as Clayton McDonald received two yellow cards.
Southend overtook Cheltenham with the victory and are just one point behind table-topping Crawley, while Vale are now six points off the top seven.
VIEWS FROM THE DRESSING ROOM
Southend United manager Paul Sturrock told BBC Essex:
"From the first minute we were on the front foot, we chased everything down and we were in their faces all over the pitch. That was the difference.
"We got the first goal and that seemed to give that wee bit of confidence back to everybody.
"I was very pleased at half-time, the second half after the own goal turned into a slight non-event with the sending-off as well. But we stuck to our task."
Port Vale manager Micky Adams told BBC Radio Stoke:
"That was an abject display. There was one side that thought they could win the game and the other side, us, didn't think we could win it.
"You can talk about systems, shape, players, but if you don't do the basics from set-pieces, you've got no chance.
"It's probably one of the worst performances I've seen from a Vale side, certainly since I've been at the football club."
