MK Dons moved into fourth place in the League 1 table and edged ever closer to the play-offs with a commanding 3-0 win over Scunthorpe United.
Dean Bowditch opened the scoring in a low-key first half before the Dons, in a dominant display, turned the screw on a poor Scunthorpe side with Daniel Powell adding a second before Shaun Williams netted a 40-yard stunner to wrap up the three points.
The hosts were sent down to 10 men in with 19 minutes remaining when an off-the-ball incident was brought to referee Carl Berry's attention by fourth official Nigel Smith and resulted in the dismissal of Jordan Robertson. At that point though, the Dons were already two goals to the good and in full control.
The one blemish for the Dons on a good outing though was a late injury picked up by goalkeeper David Martin, who has totalled 51 appearances this season. It did however pave way for Ian McLoughlin to make a late appearance and earn his League debut for the Dons.
The victory, coupled with Huddersfield's defeat to Preston, has pushed the Dons up to fourth in the table on goal difference.
The Dons, with Alan Smith back in the starting line-up in place of Jabo Ibehre, travelled to Glanford Park knowing they faced the draw specialist of the division and with the aim of ending a 10-game unbeaten run by The Iron.
There was little worthy of note to take place inside the opening 10 minutes as the tempo failed to gather in a scrappy beginning. There were hints of an interesting battle ahead between Scunthorpe's Cliff Byrne and Alan Smith as the defender closely marked Smith during David Martin's goal kicks.
The Dons tried hard to force their style of play on their hosts and in the 11th minute it proved successful. A smart pass by Darren Potter, who inked a new two-year deal with the Club two days earlier, opened up space for Charlie MacDonald on the right of the box and the striker played a fine cross in for Bowditch to finish past Sam Slocombe.
It was a bright spark in an otherwise quiet game, but it provided the lift needed and forced Scunthorpe to become a little more open in their approach. A fine through ball from midfield cut the defence in half and signs were ominous for the Dons when Jordan Robertson latched onto the ball, however, Adam Chicken marked his man well to time a challenge to perfection and null the chance.
The Iron lacked composure in front of goal and Josh Walker was guilty of wasting a golden opportunity when he went for glory from the edge of the box only to blaze over. Scunthorpe were offered another chance minutes later when the Dons' back four was pulled apart and a slip by Dean Lewington invited Mark Duffy through for a one-on-one.
However, Martin, wearing the bright pink 'keeper's kit for the first time this season, denied the midfielder with a full-stretch save at his right post.
At the other end the Dons found it harder to break through The Iron backline but a free-kick from Lewington offered them the chance to once again threaten Slocombe's goal. The skipper's delivery was headed clear but only as far as Stephen Gleeson, who took a touch and drilled into the arms of the goalie who, after an initial spill, managed to recover.
The Dons showed great desire to extend their lead after the break with some impressive football in the Scunthorpe half, both Bowditch and Gleeson were lively around the box and only a diving block from David Mirfin prevented a drilled effort from Bowditch from nestling into the back of the net.
A lovely ball from Potter invited a break from the Dons and a heavy touch from Mirfin opened up a chance for Powell, but Slocombe was fast off his line as he made the brave decision to block with his feet.
A matter of minutes later though MacDonald made inroads down the right of the box to once again he provided a fine cross into the six-yard area and this time it was Powell who was in the right place at the right time to finish at the near post.
Jimmy Ryan single-handedly was trying to drag Scunthorpe back into the game with his energetic bursts down the wings and lively play in the Dons' final third.
A stern challenge from Williams did not deter him and when he spotted the chance, he fed a fine through ball into the path of Robertson, yet the forward fluffed his line as he drag a low shot well wide.
Scunthorpe were allowing the Dons to play around them but when a rare sloppy pass went astray from Potter the Iron were given a chance to test Martin. Sam Togwell raced clear before spraying the ball to Ryan, yet another effort was miscued by the home side as the ball fell offtarget.
In the 72nd minute an incident off the ball to place between Robertson and MacKenzie, with the Dons defender left on the floor. Referee Carl Berry was flagged down by the fourth official, who had seen the incident unfold in which Robertson had raised his hand to MacKenzie's face, and the Scunthorpe man was subsequently shown a straight red card.
With a man advantage the Dons were keen to press on for a more convincing scoreline and they were denied a third when Lewington's curling free-kick came off the underside of the post.
However, a third did come for the Dons and it came in spectacular fashion as Williams unleashed a superb 40-yard drill which few through the bodies in front of him and into the back of Slocombe's net.
The victory moved the Dons ever closer to the play-offs.
