Wycombe lost ground in the play-off race as Cole Stockton's late strike handed Morecambe a 1-0 victory at the Mazuma Stadium on Saturday afternoon.
Blues were denied by a series of saves from home keeper Connor Ripley in a frenetic finale before Stockton converted to give the Shrimps hope of a great escape from relegation.
Matt Bloomfield named an unchanged starting XI from the side that defeated Forest Green five days earlier, although Sam Vokes and Curtis Thompson returned to the bench following injury lay-offs.
Blues began brightly and Tjay De Barr was inches away from connecting with Jason McCarthy’s low cross inside two minutes, before Joe Jacobson’s drive was blocked and Brandon Hanlan steered wide of the near post at the end of the same attack.
Then Chem Campbell sent a volley wide from Tjay De Barr’s clever cross before the hosts settled into the game and carved out their first opportunity when Dan Crowley headed a cross over the bar on the quarter-hour mark.
Wanderers got back on top and Lewis Wing came closest to a breakthrough, waiting patiently for the ball to come his way 20 yards out before hitting a goalbound effort which deflected just past the post for a corner.
Chances dried up as the hosts got more of a foothold in the game, getting into good areas without being able to test Max Stryjek, and Josh Austerfield’s header over the bar from a corner was the closest they got.
Wycombe threatened once more before the interval, with Campbell’s deflected effort diverting over, but it remained goalless at the break.
Jack Grimmer bundled a corner wide of the far stick with the first chance of the second period, with Joe Jacobson’s deep corner causing concern from the hosts, and Josh Scowen then did brilliantly to win the ball in midfield and surge forward, feeding Tjay De Barr who could only drill wide.
A double change came on 54 minutes when Sam Vokes and Garath McCleary both came off the bench to replace Brandon Hanlan and De Barr, and with it came a strong spell of pressure, with Lewis Wing having another shot blocked from inside the area as Morecambe sat deep.
McCleary sent a half-chance wide from Wing’s clever free-kick though Wycombe needed to stay tight at the other end, with Chris Forino in particular repelling a couple of dangerous scrambles in the box.
Vokes had a shot deflected wide when turning to meet a ball 12 yards out, and McCleary latched on to a Vokes header to race towards the area only for the defence to recover in the nick of time.
Then Joe Jacobson fizzed a cross-shot across the area but Chem Campbell couldn’t adjust himself quickly enough to convert, and David Wheeler drilled over from 25 yards.
The last 10 minutes belonged to Morecambe keeper Connor Ripley, who kept his side in it with a superb save from Lewis Wing’s header after denying Wheeler in a one-on-one in the box.
And Morecambe went and won it at the other end when a fierce drive from 25 yards flew through a crowd and Max Stryjek saw it late, parrying it but only into the path of Cole Stockton, who acrobatically converted from eight yards.
There were still chances to equalise late on, but Jack Grimmer hit the bar with a header and McCleary was denied by Ripley at the near post to prove it really wasn’t Wanderers’ day.
