Similarly to their round three triumph over Colchester United, the Beachboys scored all of their spot kicks to progress with a 5-4 shoot-out win.
The Vanarama Conference South side had entered that Colchester lottery on a high following a late comeback, but this time they had to recover from a last-gasp leveller from the away side.
Joao Carlos? angled drive levelled the tie for Ryman League Premier Division Grays in the final minute after Concord had led from the 28th minute when Lewis Taafe drilled a low effort beneath goalkeeper Connor Gough.
The equaliser was the least Grays? second-half efforts warranted having dominated the period for long spells. Ultimately they just ran out of steam in the shootout, with Freddie Ladapo – the hero of Colchester United?s 2010 success – the unfortunate man whose penalty, saved by young on-loan Arsenal ?keeper Josh Vickers, proved costly.
Concord had fired a couple of first-half warning shots as Mitchell Pinnock?s free kick dropped just over the top before the loanee Bromley man set-up Steve Cawley to fire inches wide. They took the lead four minutes after the half-hour through Cawley?s fine run which resulted in a cut-back to , who hit a firm shot between the legs of Gough.
Moments beyond the second half restart, Pinnock?s close-range angled shot brought a good stop from Gough but, despite a triple substitute from the home side, it was Grays who grabbed hold of the tie. Ladapo would?ve been disappointed to see his shot deflected inches wide following a hooked cross from Aaron Best prior to Odemie Oumake smashing marginally off-target from the edge of the box.
Ladapo then centred for Oumake to flick a deflected header just wide and the resulting Carlos corner saw Joseph Zerafa?s fierce shot blocked on the goal line by Danny Glozier. The ball was immediately recycled into the penalty area and, this time, only two blocks denied Ladapo.
That was a let-off for Concord. But, as the clock ticked into the final minute, Zerafa?s right-flank cross picked out , who drilled a low effort beyond Vickers into the far corner. The goal sent the game directly to penalties, and Concord were unfazed as they succeeded each time from twelve yards. Ladapo?s saved kick allowed Tony Stokes, just as he had in the previous round, to score the winning kick and send his side through.
