A second-half penalty from Mikel Arteta was enough to give Arsenal a win over Wigan and lift the Gunners up to third.
The Gunners were not as impressive in the first half at the DW Stadium as they had been at Reading with Alex Oxlade-Chamberlain getting the only clear-cut chance.
But despite a few defensive slips at the other end, Arsene Wenger's men went in 0 - 0 at half-time.
The Latics were hustling and harrying the opposition as Arsenal struggled to get into their rhythm.
But one-mistimed tackle in the are from Jean Beausejour on Theo Walcott - starting as a striker again - proved to be the key moment.
Arteta stepped up to calmly send Ali Al Habsi the wrong way.
Wigan had a penalty shout before the full-time whistle when a Jordi Gomez strike appeared to hit Kieran Gibbs on the arm but the Gunners held on to move above Chelsea and Spurs into third.
