Bury went in front on 32 minutes when Paul Scott fed Baker in the area and he found the corner with a smart finish.

But Peterborough were transformed after the break and Charlie Lee had a header cleared off the line by Steve Haslam.

Bury weathered the storm and caught the visitors on the break late on when Andy Bishop teed up Mangan to double the hosts' lead and seal the points.
