Latics made it three wins from four thanks to Nathan Sheron’s last minute winner.
Oldham had a good share of the chances early on, the best of which saw John Rooney place the ball just wide of the post.
Woking had their periods of dominance during the game, but failed to make anything of it.
With the game seemingly destined for a 0-0, Sheron popped up in injury time with a header to give David Unsworth’s side the win.
Latics started brightly, and created a number of half-chances in the opening minutes.
Rooney went for goal within the first 60 seconds, seeing his shot blocked and cleared.
Reid flung a half-volley towards goal, forcing Jääskeläinen to push it wide for a corner.
Rooney had another chance, which was probably the best of the game. He received the ball inside the area before going past two men and putting the inches wide of the goal.
Woking had their chances, though, Padraig Amond hit a powerful half-volley towards the Latics goal, which went wide.
The second-half saw the game become a rather scrappy affair, with lots of late challenges and 50/50s.
Despite all that, Reid was played through and went one-on-one with the goalkeeper, just to put his effort wide, albeit from a tight angle.
Young Will Sutton, playing in the unfamiliar wing-back position, looked to find Reid with a smart cross, but the Woking defence made good work of putting it behind for a corner.
With the game coming to a close, Rooney dinked a cross towards the advancing Sheron, whose bullet header flew past Jääskeläinen.
Oldham: Norman, Hogan, Sheron, Shelton, Rooney, Reid, Kitching, Sutton, P. Clarke, Yarney, Nuttall.
