A fine hat-trick from Stuart Beavon sealed a date with Cheltenham Town in the next stage of the Johnstone's Paint Trophy as the Wanderers eliminated Bristol Rovers in tonight's first round tie at Adams Park.
The lively forward was full value for his treble, turning in a fantastic and clinical performance in front of a crowd of 771, opening the scoring on just eight minutes with a left-footed drive into the corner.
His second came on 57 minutes when he beat the visiting keeper from outside the area, although the hosts were given a scare when former Blues striker Matt Harrold reduced the arrears by taking advantage of a lapse in the home defence.
However, Wanderers were not to be denied a first home victory of the season and Beavon put the icing on the cake with another delightful finish on the turn, having earlier struck the crossbar at the end of a scintillating run.
With the impending visit of local neighbours Brentford to Adams Park for Saturday's npower League 1 clash, Gary Waddock made five changes to the side that started the Blues' last fixture at Huddersfield Town 10 days ago.
However, the reshuffle didn't affect the strength and experience within the team, with Elliot Benyon, Stuart Beavon and Scott Rendell interchanging in a front three, while the visitors included former Wanderers Matt Harrold and Scott McGleish in their attack.
Harrold saw his effort deflected wide in the first chance of the game inside five minutes before the hosts took the lead with their maiden effort, as Stuart Beavon capitalised on a defensive slip to fire home calmly past his namesake Scott Bevan - also a one-time Wycombe player.
Chances were few and far between in a tepid first half, although Harrold had another sight of goal when his low shot ricocheted wide, before Matt Bloomfield almost caught Bevan out with a shot from 25 yards which was pushed around the post with five minutes of the half remaining.
Eliot Richards fired straight at Nikki Bull after the restart before Scott Rendell headed Marvin McCoy's cross into the side netting as the home side looked to put the game to bed, although Rovers came close to an equaliser when Scott McGleish's acrobatics were denied by Nikki Bull.
Wycombe's second goal came on the counter-attack from the resulting corner when Kevin Betsy was released down the left and he fed Beavon, who found space to send an arrowing shot into the bottom corner from outside the area.
However, the two-goal advantage lasted barely two minutes as the League 2 club gave themselves a lifeline courtesy of Matt Harrold, who squeezed between two defenders to drill a left-footed drive past Bull with still half an hour to play.
The quickfire goals brought the game to life and Beavon came close again when he wriggled away from the Rovers down the left and cut inside before firing against the crossbar from 12 yards.
However, he wasn't to be denied his first hat-trick for the club when he received Kevin Betsy's cross on his chest and turned away from the defenders before hitting another low drive past Bevan for his fourth goal of the season - all of which have come in cup competitions.
It was his last action of the game with Kadeem Harris taking his place although the visitors refused to accept defeat, seeing McGleish's header sail over the bar before Richards' shot was palmed around the post.
Scott McGleish missed the target with a header in stoppage time and as the final whistle sounded, the Blues were able to reflect on a satisfying victory over one of the League 2 promotion favourites, securing their place in round two of the competition.
