Superb Oldham swept aside a poor Bradford with a 3-0 Sky Bet League Two victory.
Zak Dearnley took advantage of a Bantams defensive mishap to give Oldham an early advantage before Jonny Smith doubled their lead.
Mohammed Maouche added a third before the break as Bradford dropped out of the play-offs and Oldham recorded back-to-back wins.
Kick-off was delayed until 3:30pm at Boundary Park after an advertising board became partly dislodged and had to be removed.
When the action started, Bantams defender Anthony O’Connor slipped after 10 minutes and Dearnley finished coolly past Richard O’Donnell.
The Latics doubled their lead after 20 minutes when Gevaro Nepomuceno teed up Smith on the edge of the box and he curled in a delightful shot.
A commanding Latics first half and a miserable one for the Bantams ended when Maouche slipped in behind the Bradford defence after a flick on to nutmeg O’Donnell for Oldham’s third.
O’Donnell kept out efforts from Smith, Nepomuceno, Maouche and Christopher Missilou after the break as the Bantams had a day to forget.
