Two of League One’s highest scorers played out a surprising goalless draw at the DW Stadium. League leaders Latics failed to hit the net for the third home game in a row as their strikers had another off day.
They did have several good opportunities to break the deadlock and League One Player of the Month Dan Burn might have got on the score sheet after a rare sortie forward but his final shot was well blocked.
The Posh matched Latics for possession in an even encounter and might have won it at the death but Jack Marriott’s effort was ruled out for offside.
Despite the draw Latics extended their lead at the top of the table to three points after second placed Shrewsbury lost 3-1 at third place Blackburn.
Paul Cook kept the same starting line-up that had done so well at AFC Bournemouth in the FA Cup, with new signing James Vaughan on the bench.
Michael Jacobs was involved in several chances as Latics made the early running.
But the match only fitfully sprang into life as neither team created a clear cut opening.
Jacobs did force a good save from Posh keeper Jonathan Bond with his 20-yard drive on the half hour mark.
It looked likely that Posh would be dangerous from counter-attacks but it was just before half time before they threatened through an acrobatic Marcus Maddison volley.
Early in the second half centre-back Dan Burn made a surging run towards the Peterborough box and just when the DW Stadium was about to rise to applaud the fans’ favourite, his goal bound strike was well blocked by a defender.
Posh then threatened through the prolific Marriott but his low drive from distance was well saved by Christian Walton.
Gavin Massey then went close for Latics forcing a good save from Bond low down at his near post.
James Vaughan and Ryan Colclough replaced Will Grigg and Massey as Latics looked to unlock the Posh defence.
Colclough missed a golden opportunity when he completely missed his kick when inside the penalty area, before Nick Powell’s rising drive which was destined for the top corner was headed away for a corner.
Latics just couldn’t make the breakthrough and the visitors nearly claimed the three points when Marriott followed up a long range effort but the flag was raised for offside.
Despite Latics’ failure to score the team had extended their lead at the top, they are now 11 games unbeaten having secured their seventh league clean sheet in a row.
