Ashley Chambers' 89th minute strike salvaged a draw for the Wanderers away at 7th placed Swindon on Saturday afternoon.
The 19-year-old, who is on loan from Championship side Leicester City, came off the bench with 15 minutes remaining and fired low past David Lucas from a Matty Phillips cross to send the 421 travelling Chairboys fans into delirium.
Swindon had earlier taken the lead at The County Ground through Kevin Amankwaah and will count themselves unfortunate not to have snatched all three points after Billy Paynter's header was expertly saved by Scott Shearer in the 93rd minute.
Peter Taylor made four changes from Saturday's 1-0 defeat to MK Dons and it was one of his replacements, Jon-Paul Pittman, who had a glorious opportunity to put the Blues ahead on two minutes. Kevin Betsy did well to wriggle away from the challenge on the edge of the Swindon area before playing in Pittman, but from 15 yards out 'JP' dragged his shot wide of David Lucas' goal.
Wanderers continued to control the early proceedings but found themselves 1-0 down on 17 minutes when Amankwaah drilled a shot under Shearer from the right corner of the penalty area.
The Chairboys picked themselves up and Chris Zebroski had the ball in Swindon's net no longer than 10 minutes later, but his effort was ruled out for handball by referee Mr. Hall.
That seemed to fire a warning shot to the hosts and Jon-Paul McGovern and Jonathan Douglas began to pull the strings in central midfield for the Robins. And McGovern's class nearly brought about the second goal for Danny Wilson's men on the half hour but his 30-yard effort hit the inside of the post before rolling along Shearer's line and behind for a goal kick.
Stuart Green responded for the Blues five minutes later with some quick thinking from a free-kick, although he wasn't able to keep his shot down from a similar distance as McGovern's earlier effort.
Taylor, unlike Saturday against MK Dons, decided against any substitutions at the interval, and he would be rewarded for sticking with his starting eleven as the Blues began to pick up their game and offer a stronger attacking threat.
However, it was Swindon and the impressive Temitope Obadeyi who notched up the first chance of the second half. The winger cut in from the right onto his left-foot and unleashed a shot from 20 yards, which whistled past Scott Shearer's left post.
Whilst Swindon had Obadeyi, Wanderers had Kevin Betsy and the winger's direct approach brought about a chance for Chris Zebroski as the clock ticked past 50 minutes. Betsy out muscled his marker down the right, whipped in a teasing cross but 'Zebs' couldn't get enough power on the shot and his effort was easily gathered by Lucas.
Provider nearly became goalscorer five minutes later, although Luke Oliver's through ball couldn't match Kevin Betsy's fantastic surge from midfield and Swindon's number one was alert to come out and claim.
With Taylor sensing an equaliser the Blues boss made an attacking substitution on the hour mark, replacing right-back Lewis Hunt with winger Matty Phillips.
Phillips' introduction had an instant impact and he had a hand in the Wanderers' next chance. His pass found Jon-Paul Pittman 25 yards out and after taking advantage of a defensive slip he stung the fingertips of Lucas on 70 minutes.
That proved to be JP's last major contribution though as he was replaced by Ashley Chambers five minutes later. The Leicester youngster operated down the left-hand side and within two minutes of entering the field he had an opportunity to draw the Blues level.
However, after arriving unmarked in Swindon's 18-yard box he snatched at a left-foot volley, following good work from reverted right-back Lewis Montrose.
Chambers would have the last laugh nine minutes later though after he stole in at the back post and coolly slotted home his first league goal to hand the Blues a deserved point. The Leicester youngster will receive the plaudits for his calm finish but credit most also go to Phillips for his role in the goal - the winger broke down the right hand side, staying on his feet after being fouled by Jean-Francois, and then picking out the 19-year-old at the back post.
There was still time for Shearer to pull off a fantastic save to deny Billy Paynter from six yards in the 93rd minute and that stop proved to be pivotal with referee Hall bringing an end to proceedings moments later.
