The game marked Nathan Bowden-Haase’s 100th Slough appearance, and he received an award before the match along with Dan Burnell.
In truth, Slough could well have been two or three goals behind at the interval. Ricky Case saw his effort from the edge of the box bounce off the bar and over, and Bowden-Haase appeared fortunate to escape punishment when dragging down Aaron Lansiquot in the penalty area.
But with 36 minutes played, there was no such luck for Slough as Lansiquot opened the scoring for the visitors. Case brought the ball into the box and laid it off for the striker, whose side footed effort deflected past James Warrington and rolled agonisingly into the far corner.
Alex Brown then performed heroics almost immediately after, running back to clear off the line. But four minutes after going behind, Ed Smith levelled with a neat volley across Barton 'keeper Richard Wilmot, the ball going in off the far post, after a super run and cross from Jake Parsons. The goal had come just after Slough had altered their formation, with Sean Fraser reverting to right-back and Parsons on the right wing, with Slough having previously struggled to make an impression.
Thirteen minutes into the second half, after Dan Burnell had been off-target with a couple of snatched shots, Slough took the lead with an impressive piece of skill from centre-back Alex Brown. He capitalised as Barton failed to clear a deep cross, showing good control and a drag-back which fooled the Barton defence and allowed him space to fire past Wilmot.
Burnell then missed a glorious chance to head Slough 3-1 ahead, but put his header wide of the post.
Jake Parsons, who had an impressive game before tiring in the second half, was denied a goal by a good block from Wilmot.
Slough continued to create chances, with Burnell dragging a shot wide before setting Ed Smith up to volley a foot wide. Barton were hampered by the dismissal of defender Nick Leach for two bookable offences, and Slough struggled to close the game out until four minutes into time added on, when Smith beat Wilmot for a second time with a mis-hit shot which deceived the experienced keeper.
