Wingate and Finchey dropped out of cup competition for the second time in a week with a 3-2 (AET) loss at home to Brentford B in the quarter-final of the London Senior Cup.
Sean Cronin scored two on Saturday and he gave the Blues their first half-time lead in four games with the opener on Tuesday.
And Brentford’s equaliser straight after the restart and later penalty were cancelled out by a yet another Cronin goal.
But another Bees penalty in extra-time consigned Wingate to their fifth straight defeat and just a Bostik Premier League relegation battle left to focus on.
On Saturday, the Blues went 4-0 down before finding the back of the net but Tuesday’s game couldn’t have been more different.
A dominant first half saw Cronin fire home from the edge of the box after half an hour and Charlie Ruff came close to doubling the lead with a shot just before the break.
But just two minutes into the second-half Troy Archibald’s touch spun off Shane Gore to the feet of Marcus Forss, and the Finnish striker tapped Brentford level.
The Bees fought hard for the lead - Reece Cole’s free-kick forced Gore into an excellent save on to the crossbar.
It eventually came in the form of a penalty after David Titov was brought down in the box, Joe Hardy stepping up to put Brentford in front.
But with 10 minutes left of normal time Cronin headed Wingate level off the crossbar from a free-kick, and he wasn’t done yet.
Troy Archibald rounded Gore and rolled a shot towards goal that Cronin was able to hoof off the line with just seconds left on the clock.
But a spirited performance from the Blues proved to be in vain after Matej Majka was brought down in the box in the 112th minute of extra-time and Hardy stepped up again to score the winning goal from the spot.
The Blues now have a tough test away to third-placed Lewes on Saturday as they look to climb out of the bottom three.
