An early strike from Scott Kashket secured a 1-0 victory at Wealdstone to continue Wanderers' unbeaten pre-season campaign so far.
The striker buried Nick Freeman's incisive pass and the Blues had chances to stretch their lead in the second period, most notably when Jason McCarthy saw a late penalty and follow-up saved by the Stones keeper.
Craig Mackail-Smith also saw a shot bounce back off the post before Matt Bloomfield's effort from the rebound was cleared off the line.
