Mark Carrington's first-half goal proved decisive as MK Dons kept their slim play-off hopes alive with a narrow 1-0 win over Leyton Orient.
Midfielder Carrington headed in the only goal of the game in the 31st minute and the Dons missed a host of other chances as they cruised to victory over the lacklustre O's.
The Dons enjoyed total control of the first half and Luke Chadwick and Dean Lewington both went close before Carrington put them ahead.
Carrington nipped in ahead of goalkeeper Jamie Jones to nod in Aaron Wilbraham's clever chip from close range for his fifth goal of the season.
Chadwick should have doubled the Dons' lead soon after the break but his low shot was well saved by Jones, after Carrington's quick free-kick had sent him clear.
Mark Randall and Jermaine Easter then blasted efforts narrowly wide for the hosts before Lewington headed Peter Leven's free-kick just over the bar.
Leyton Orient finally applied some pressure in the closing stages and substitute James Scowcroft's fierce 15-yard volley was saved at full-stretch by keeper Willy Gueret 10 minutes from the end - their first shot on target.
