Slough managed to get themselves in front in the 21st minute. Leigh Mason collected a Folkestone clearance and passed the ball back into the box. Martin Chandler missed an easy clearance which allowed Charlie Ide to run in off the back of him and despite being pulled back, managed to lift the ball over Tony Kessell as he advanced to close down the Slough forward.
A few half chances fell to the visitors following the dismissal of Woodruffe after the defender had picked up his second booking, but never troubled Masters.
The start of the second half saw Slough continue to have the better chances in the game. Leigh Mason played a delightful cross field path into the run of Glen Harris and the midfielder struck his volley well, but found Kessell well placed to get a block on the shot.
Michael Alexis put the gloss on the performance with just under twenty minutes left. Josias Carbon got in down the right hand side and the defender squared the ball unselfishly to the run of Alexis to allow the midfielder a simple finish from the middle of the goal.
Slough lost keeper Clark Masters to injury after he took an elbow when claiming a high ball and fortunately Slough had a keeper in Michael Parkin on the bench, but one which inspired nerves amongst the defence in front of him. Steve Norman delivered a high ball into the box which the sub keeper made a strong call for but got nowhere near as Adam Flanagan won his header but sub James Fraser could not capitalise and hit his volley wide.
Parkin though did show his quality which had earned him the number one shirt the previous season as he did well to deny Fraser when the striker was well placed at the back post.
Ashley Hames time in charge will have just about secured Premier Division football for the Rebels as they can look to begin their preparations at this level for the next season.
