Report: Wycombe 1-0 Leyton OrientScott Kashket was the hero once again as he netted a second-half winner against his former side to earn the Chairboys an eighth consecutive win in all competitions.
The 20-year-old was on hand to turn the ball home after Alex Cisak had denied Paris Cowan-Hall soon after the break, and the imperious Wycombe back five - with Dominic Gape superbly shielding in midfield - did enough to repel their visitors to ensure they would claim all three points in the final home game of 2016.
Gareth Ainsworth handed Garry Thompson a start in place of the suspended Adebayo Akinfenwa, but it was an otherwise unchanged starting line-up as the Blues took on an Orient side arriving with confidence after a 1-0 win last weekend.
The away team applied early pressure via a series of set-pieces while Kashket drilled the first chance wide, meeting Aaron Pierre's knockdown with a first-time effort.
Kashket then tested the handling of the keeper with a long-range effort before O's dangerman Jay Simpson fired wide when well-placed inside the box.
Orient then thought they'd broken the deadlock when Paul McCallum turned home Simpson's cross-shot only to be denied by the offside flag, with no more chances coming before the interval.
There was a change in the middle at half-time when Alan Young replaced injured referee Rob Lewis, and within five minutes he was adding Scott Kashket's name to his notebook for converting his 11th goal of the season.
The striker ran to salute in front of the directors box as a well-timed reminder of his abilities to the Orient hierarchy, who had frozen him out from their club and allowed him to move to Wycombe in August.
Soon after, Orient left-back Callum Kennedy was stretchered off with a nasty looking injury, but despite a flurry of substitutions they were unable to test Jamal Blackman as the game drew towards its conclusion.
In fact there were late opportunities for the Chairboys to extend their lead, with Aaron Pierre and Sam Wood firing wide while Matt Bloomfield headed over.
