The two sides exchanged chances in the opening stages with Shane Smeltz hitting a long distance drive which nearly caught Michael Parkin unaware but the keeper recovered to save with his legs.
Slough's opening chance fell to Ian Hodges. Josias Carbon made good progress down the right hand side and squared the ball to Hodges. The strikers curling effort went just over the far angle of the goal.
The Dons took the lead with twenty minutes gone. Finnie broke up a Slough attack and the ball was cleared to the right. Fed into the box, Woolners header thundered against the bar and back out of the box. Slough regained the ball but failed to clear as Smeltz won the ball back, got through two Slough defenders before sidefooting firmly across the goal into the left hand corner.
Slough were struggling to create anything of note but at the same time were limiting the Dons to the same views of Parkin's goal as neither keeper had a save of note to make for the remainder of the half.
Slough started the better of the two sides in the second half and had the first opportunity as the ball was fed into the diagonal run of Brooks but he could not direct his effort on target. Slough again went close as some good build up play saw the final pass just behind the run of Brooks and he was unable to get his foot around the ball as it spun just wide.
Slough were continuing to press and looked the most likely to score but just couldn't get the final touch or shot on the chances they were creating.
Slough were left to rue their missed chances as in the final minute, a ball through from right back Wes Daly was met by the run of Barry Moore and the midfielder headed the ball past Parkin who had come to collect at the edge of the area. Despite the best efforts of Steve Daly to get to the ball it hit the back of the next and put the gloss on the win for the Dons who maintained their perfect start to the season.
