Goals from loan duo Diego De Girolamo and Stephane Zubar could not prevent the Minstermen from losing 3-2 in a performance strewn with defensive errors that visiting marksmen Jake Goodman, Sean Rigg and Matt Tubbs capitalised on.
The defeat means York will now take an unwanted place in the Bootham Crescent history books, alongside the club’s 1981-82 team, if they fail to overcome visitors Accrington Stanley on Boxing Day.
Manager Russ Wilcox did not feel, however, that the sorry sequence is beginning to take a psychological toll.
He said: “The longer it goes on, the more pressure it creates, but I don’t believe the players are feeling it I’m sure”
Goodman headed the Wombles in front from George Francomb’s corner but on-loan Sheffield United striker De Girolamo equalised early in the second half with his fourth goal for the Minstermen – a spectacular 15-yard strike after his close control bamboozled two markers.
Mistakes by Femi Ilesanmi and Zubar, though, saw Wimbledon claim two goals in as many minutes just past the hour.
Francomb was given an opportunity to cross the ball in from the right on both occasions with Rigg tapping in from three yards and Tubbs heading home.
A scrambled 75th-minute effort by Zubar proved scant consolation for the hosts.
