Kingstonian had three chances in the first fifteen minutes, which saw Peter Barnsby and James Pinnock's chances each saved by the Slough keeper Dominique Jean Zepherin. Slough's first chance came soon after, an excellent run down the right by Byron Bubb but his cross was not met by the Rebels attack.
Dominique was once again the hero at the other end, this time pulling of another scorching save from Tom Stills. But soon after a poor clearance from Kingston keeper Mark Jones saw the ball come to Andy Deaner, and his wild swing at the ball saw it soar over Jones' head from forty yards, as Slough took the lead. Near the end of a reasonably quiet half saw a slick Kingston attack including T Stills and Scott Steele, but Nick Gyoury's slice saw the ball just creep over the bar.
Kingstonian once again started the half the better side, a free kick taken by Sean Thurgood was deflected wide off Slough defender Dean Palmer's sock.
Minutes later saw a super cross from James Pinnock which Kingston striker Scott Steele met for a great half volley goal, the equaliser on the 53rd minute. Kingston pilled on the pressure and a Chris Ferdinand tackle at the ball saw it roll to the feet of Tom Stills but Dominique yet again pulled off another super save.
Steve Browne a couple of changes soon after, replacing Dean Palmer and Tony Boot with Adrian Brown and Ryan Spencer but Stills was not put off, a high leap saw his headed chance hit the bar. Slough's only chance of the game came in the dying minutes, a Byron Bubb cross was too early for the slow Andy Deaner.
Just before the whistle saw the third change for the Rebels, Christian Metcalfe replacing the tired looking Chris Ferdinand.
Extra time saw the first change for Kingston, Liam Collins coming on for Phil Wingfield. Once again Kingston came out on top, another headed effort by Tom Stills once again hit the bar but he made amends for this by tapping in a spill from Zepherin minutes later. The second half was much more dismal, a tireless effort of a clearance from Anthony Howard saw Stills score his second of the night and clinched the 1-3 win for Kingstonian who deservedly progress in the Bryco Cup.
