The visitors extended their aggregate lead to 6-2 in just the fifth minute and must have thought the tie was away from Slough as Lenny Piper was played in on the left and his low effort found the far corner. Certainly not the start Slough would have wanted as they chased a big margin.
Leigh Mason had Slough's first chance of the game and shouldhave done better, but whilst he forced James Pullen into a save, it was a good opportunity wasted.
Piper again forced Masters into another good save as his near post and then Slough drew back onto level terms on the night on the stroke of half team as Gareth McCleary cut inside from the left and his pass directed towards an unmarked Ian Hodges was diverted into his own net by Jason Rose.
Slough got off to the perfect start in the second half as Fisher gave the ball away cheaply to Hodges on the half way line. He was able to pick his pass and roll the ball forwards into the path of McCleary's run and the young striker made no mistake finishing confidently across Pullen.
Slough should have added their third when Hodges forced a mistake from the home defence as and the ball fell to McCleary he should have done better as Pullen was able to comfortably claim with much of the goal gaping.
Damien Scannell saw an effort blocked by the feet of Masters, but generally Slough were snuffing out what was still an extremely good front line which had already put eleven goals past the Slough back line in three and a half games.
Captain Steve Daly got himself on the scoresheet with seven minutes remaining and with Slough being firmly on top, could they complete an astonishing comeback? Quite simply, no. Fisher were able to regroup and repel the late pressure from Slough to win 6-5 on aggregate and head into the final against Billericay Town.
