Scott Kashket's first-half header was enough to secure a 1-0 win for the Chairboys in a practice match against Stevenage on Saturday afternoon.
On a sweltering afternoon, there was a quiet start to the game with Jordan Obita's powerful drive being the only notable chance of the first half-hour, drawing a fine save from the Boro keeper.
Wanderers stepped up the tempo before the break and Malachi Linton's low chance was cleared off the line before Scott Kashket stooped bravely to head home from Oliver Pendlebury's superb cross.
There were nine changes at the interval, and it was Wycombe who looked more likely to add to the goal tally, with a trialist striker rifling narrowly over from outside the box, Alex Samuel going close with a header, and Jason McCarthy's bullet header being well saved by the keeper.
