CONCORD stumbled into the next round with a lacklustre performance against their spirited Wessex Premier League visitors, writes Jack Smith.
That said, the Beachboys started well and took a 32nd minute lead when Steve Cawley capitalised on a defensive error and lobbed keeper Jason Collins from 45 yards out.
Winchester were soon level, though, when a goal-ward header was hooked into the bottom right corner by Warren Bentley.
But the visitors still went in trailing at half-time as Cawley added a second when he tapped home after good work from Joe Gardner in front of a crowd of 202 at the Aspect Arena.
Concord were wasteful in the final third but managed to score a third when Steve King powered a header against the crossbar before fellow centre-back Matt Fry followed up to smash home the rebound.
City were gifted a chance to reduce the deficit when King felled Bentley and the referee pointed to the spot.
Bentley himself took the penalty and sent keeper Aaron Lennox the wrong way to give his side a glimmer of hope.
But Concord used their experience to see out the final 15 minutes and put themselves in the hat for the fourth qualifying round on Monday.
