Swindon stretched their unbeaten run to three games after a 2-1 win over Northampton Town at the County Ground.
Town were forced into a change before the game had kicked off when emergency loanee Jojo Wollacott was injured in the warm-up and was deemed not fit to play. In stepped academy graduate Archie Matthews to make his professional debut for the Club.
Northampton took the lead through Ryan Watson just before the half hour mark, firing low underneath the debutant Matthews.
On the stroke of half-time, Town got back on level terms through an exquisitely placed free-kick by Scott Twine.
After the break Brett Pitman headed in Jordon Garrick's cross, which proved to be the match winner for the Reds in the League One six-pointer.
With Matthews in the net for the first time, this was a game that could potentially be a turning point in the Club's bid to avoid relegation to League Two.
In what was a quiet first twenty minutes, the match was fairly even with Town having the best chance of the clash when Matty Palmer's pacy cross was met by Tom Broadbent, but the defenders header was too high and Mitchell in the Northampton goal saw it over for a goal kick.
The Cobblers were forced into a change on twenty-five minutes when former Town man Alan Sheehan was replaced by Fraser Horsfall.
Within minutes of the substitution, the away side were in front through Ryan Watson. A high cross from Peter Kioso wasn't dealt with and Watson showed quick feet and drilled past Matthews to give his side the advantage.
Following the visitor's goal, Town looked the more likely to score when Palmer's out-swinging corner was met by Pitman, but the striker's header curled wide.
Twine also went close when he lined up a shot from just outside the box, his effort just wide of the left hand post.
As the board was shown for additional minutes, Twine burst towards the Northampton box and was brought down twenty-five yards from goal.
The 21-year-old stood over it immediately and struck it into the top corner. Mitchell got a hand to it, but the set-piece was too powerful for him to keep out.
The second forty-five minutes come the end of the season could be one of the most important we've played and Town were determined as ever to try and find a winner.
Matty Palmer went into the referee's notebook when he stopped a Northampton attack just inside their defensive half.
Just before the hour mark, the Gaffer delved into his resources and made the first change of the afternoon for Town, bringing off Dom Thompson for Hallam Hope.
Palmer created another good chance when his free-kick was delivered into a dangerous area, although it eluded everyone's head and Conroy couldn't stop the set-piece from going for a goal kick.
Northampton tried to catch Town on the counter-attack once more, this time Marshall being brought down by Jonathan Grounds, who was cautioned for his troubles.
With twenty minutes left to play it was the man who has scored so many vital goals for Town this season that rose to the forefront.
Garrick got the better of Mills in what was a fascinating battle on the right wing, looped a cross over and who else but Brett Pitman was there to header into the net. Mitchell tried to get back, but was not successful and even pulled the netting off the support poles.
From then on in it was a nervy affair for Town as Northampton pressed further and further trying to find the equaliser.
With five minutes left to play, Twine had the chance to make it three when Garrick's low cross was cleverly dummied by Pitman and Twine's curling effort was well dealt with from Mitchell.
Despite a lengthy six minutes of added time, Town held firm and now make that back-to-back home wins for the first time since the beginning of the season.
The lads face a tough week ahead with away fixtures with Sunderland and Accrington Stanley, but with the recent performances they've put in, they'll be looking for positive results on the road.
