Second-half goals from Stephen Gleeson and Jacques Maghoma helped Blues maintain their unbeaten start in front of a fantastic travelling support.
Over 4,000 Bluenoses made the trip down the M1 and they were treated to an impressive second-half performance, which included two excellent goals.
Kick-off was delayed by ten minutes, due to an official picking up an injury during the warm up.
Both sides settled into a shape for a rather low key start and Jonathan Spector recovered well after having the ball off toes just outside the area, whilst Maikel Kieftenbeld’s through ball was just too heavy for Clayton Donaldson.
The hosts had the first opening through former Blues loanee Rob Hall. Sam Gallagher wriggled past Jonathan Spector on the by-line, cut the ball back to Hall on the penalty spot, but the midfielder wasn’t able to connect and Blues cleared.
Blues responded with David Cotterill going close from the left. The winger picked up a Dons stray pass, drove towards the penalty area down the right and tried a curling right-footer, which just went past the post.
A Demarai Gray run which eluded three players down the right came to nothing and the game lost it’s end of season feel and kicked into life.
The hosts went close on 25 minutes when Rob Hall created space on the edge of the area and shot a fierce effort just wide of the top corner.
And just a few moments later Blues broke through an excellent Jon Toral tackle, which found it’s way to Stephen Gleeson. Gleeson looked up and found Clayton Donaldson down the left channel with two defenders for company, but the striker’s low side footed effort was blocked and cleared.
Blues started to look the more confident and an excellent backheel from Gray found an overlapping Jonathan Grounds, but the defender’s dangerous cross was headed away.
With the half winding down MK Dons had the best chance of the half through Samir Carruthers. The striker burst in on goal from right of the penalty area and poked a shot high into the sidenetting with the left side of the goal gaping.
A 25-yard effort from Maikel Kieftenbeld was well-struck deep into stoppage time, but it was straight at David Martin and that concluded the first-half.
Half-time: MK Dons 0 Blues 0
Neither side made a change during the break and both teams came out with plenty of urgency.
Michael Morrison did well to block a Carruthers effort five yards from the edge of the area and a Sam Gallagher back post nod down was too heavy for Bowditch.
For Blues, Demarai Gray was starting to have an impact down the left against substitute Lee Hodson and his pass inside the area to find Donaldson was just cleared.
Jon Toral was replaced by Jacques Maghoma on 54 minutes, with Gray coming inside to play behind Donaldson and Blues hit their stride with an immediate goal.
Paul Caddis found Donaldson down the right and laid it back to Gleeson who swept it into the far corner with his right foot for an exquisite finish.
Blues took control and it should have been two. Gleeson burst into the area and hit the byline, but his reverse pass ran across the six-yards box and missed everybody.
Blues were forced to make a change with David Davis replacing Gleeson after he had stayed down from the cross. Medical staff immediately were on the scene, as the midfielder needed attention following a robust tackle.
With less than 15 minutes to go the game heated up with Demarai Gray booked for pushing Kyle McFadzean after the two collided away from the ball.
And Blues doubled their advantage through excellent build up play just minutes later. Grounds fed Donaldson, knocked it through to Maghoma, who ran on to it and slots it low past Martin.
It was a goal of great confidence and Blues had it in abundance as they went close to a third. A lovely one-two between Cotterill and Davis, fell back to the latter, who eight yards out shot wide.
It would be the last chance with Blues enjoying plenty of possession in the final third and Gary Rowett will be delighted the unbeaten start continues.
