Swindon got off to a bad start going down 1-0 after only 70 seconds when Adam Barrett was able to score from a close range header.
Andy Gurney took a Swindon free kick from 25 yards out, and but his shot was saved. Rory Fallon also came close to scoring in the first half with a header, but from close range the ball somehow went over,
Swindon went into the break losing 1-0 in what had been a poor half. Apart from Southend's early goal they had rarely looked like scoring, although Tom Heaton in the Swindon goal had been forced to make a couple of good saves.
At the start of the second half Swindon bought on Tony Thorpe, and Ricky Shakes replacing Jamie Cureton and Gareth Whalley who was injured just before half time.
Rory Fallon came close again with a header, but this went just wide. Christian Roberts also came on for the final 20 minutes but this still wasn't enough for Swindon to score.
On 87 minutes Southend scored their second goal with a close range header from Wayne Gray which sent about half of the very poor crowd of 4,785 home.
Rory Fallon put Swindon back in the game with a late goal at the end of normal time with a close range goal, and then Swindon had their best moments of the game, and came very close to getting an equaliser in stoppage time with Fallon coming close again.
The game finished with Southend winning 2-1 in what had been a very poor game. Throughout the game their were calls for Andy King to be sacked, and Swindon only looked like they would score in the final 5 minutes of the game. Southend were also on average at best, but they took their chances and came away with all 3 points. Swindon now travel to the south coast next Saturday to play Bournemouth.
