After a 2-2 draw between the two sides on Saturday, in which Sholing fought back from two goals behind, the Rebels knew they would be in for a tough evening and so it proved, although in the end the National League South side deservedly won through.
Mark Nisbet came back into the side to replace Guy Hollis, one of the Rebels’ better performers on Saturday but unavailable on the night.
Slough had the better of a frantic opening quarter of an hour, but only had a James Dobson strike at goal to show for it, which was well held by Ryan Gosney in the Sholing goal.
Then, on 22 minutes Ben Harris was tripped in the penalty area and Slough were awarded a penalty kick for the fourth match in succession. Dobson successfully converted the previous three, but this time was denied by a fantastic save from Gosney, who tipped his effort onto the crossbar with Sholing able to scramble the ball away to safety.
The ‘Boatmen’ held Slough at bay for the rest of the half and almost scored themselves early in the second period, but the Rebels cleared in the goalmouth after Pete Castle made contact to send the ball goalwards from a corner.
The game then followed a similar pattern to the first, with Slough dominant in possession and looking to break Sholing down, with the hosts looking to threaten from set plays.
But Sholing missed a presentable chance to take the lead on 68 minutes as the ball broke to Jamie Bulpitt, but Jack Turner saved with his legs. Just seven minutes later, Dan Mason – scorer of two goals at Arbour Park – also fired wide after turning his man.
Slough found the back of the net on 79 minutes as Ben Harris touched the ball in, but with a hand, resulting in a caution.
One last chance arrived in the final minute for Slough, but a free header from Matty Stevens flew wide of the goal.
Extra time followed, and Slough made the perfect start just three minutes in as they finally found a way past the resolute Sholing defence, Lee Togwell heading in at the back post from Dobson's inswinging corner.
A second goal quickly followed as Slough all but killed the contest – this time Dobson was not to be denied as he crashed in a shot from 20 yards via a post, giving Gosney no chance.
Sholing’s brave resistance was broken, and Slough added a third on 109 minutes as Josh Jackman cut in from the right and struck the ball across Gosney and in off the far post.
