Ben Tollitt struck during the first half as Latics played out a draw at Maidenhead United.
David Unsworth’s side had to withstand a significant physical test at York Road and looked as though they would overcome the challenge until Charlee Adams equalised with a late penalty.
Tollitt netted for the fourth time this season with half-time approaching and it came at a time when Latics were posing an increased threat.
The visitors could have added to their lead after the re-start as they displayed a good level of control but Adams intervened 16 minutes from time.
Unsworth again opted to start with a system consisting of three central defenders, Lois Maynard featuring in the middle of the back-line on his league debut after a lengthy lay-off with injury.
Maynard, who signed in the summer from Stockport, was a beacon of strength for Latics in the face of the aerial challenge Latics faced, flanked by James Carragher and David Okagbue.
The opening goal came just after the half-hour and was the result of tenacious work from Fondop. Having chased down Will De Havilland, the Latics striker dispossessed the defender before feeding the ball across goal, allowing Tollitt, arriving at the far post, to convert from close range.
It was a goal that Unsworth’s side deserved, as they began to carry a greater attacking presence as the half went on.
Tollitt had earlier laid the ball back to Fondop but his shot from 25 yards was always rising, while a cross from John Rooney was claimed goalkeeper Dan Gyollai after combing well with Mitch Roberts before Charlie Cooper also had a chance.
In the main, Latics dealt with was asked of them, Carragher cutting out a cross from Cole Kpekawa before Magnus Norman held the follow-up from Ryan Upward, while Adams also went close with a free-kick.
Once ahead, Latics could have extended their lead, Rooney going close after spotting Gyollai off his line early in the second half before the Maidenhead goalkeeper produced a superb reflex save at point-blank range to deny Fondop, who did well to peel away at the far post and connect with a free-kick from Tollitt.
Luke Burgess, on as a half-time substitute, was also denied by Gyollai, before he and Tollitt were foiled after a counter-attack led by Fondop.
Yet the with their physical presence, the home side posed an increased threat, Norman showing his reflexes to produce a stunning save Emile Acquah.
Maidenhead equalised when Adams converted from the spot-kick after Carragher was judged to have handled.
Gyollai held a header from Maynard as Latics tried to find a second but in the end the visitors were left to settle for a point.
