Wanderers substitute Callum Spooner’s mis-directed cross from the right touchline, dipped over unlucky home keeper Chris Sanna and dropped just inside the far post to the give the visitors their victory.
Colwyn Bay’s Chris Sharp had forced Bolton keeper Ross Fitzsimmons to turn a shot round the post for a corner early in the game, but Bolton took the lead on 38 minutes through George Newell, after Sanna had made a fine save to keep out a shot from John Ceberio, who had earlier had a shot cleared off the line.
The Seagulls had defended well, however, and equalised two minutes into the second half when Sam Barnes scored at the far post following a corner.
Sanna made good saves at the feet of Bolton substitutes Chris Cvetko and Kaiyne Wollery, only to be caught out by Spooner’s late winner.
Manager Ash Hoskin said he was “very pleased” with the overall performance.
“This was only our third game and we were playing against full-time Championship cub players who train together every day, so I thought we did well and were a bit unlucky to lose to a goal like that.
“We are making small strides all the time and the players are starting to understand each other’s game which is important.”
He’ll be looking for the side to make another step up against Bala on Tuesday night.
