MK Dons hit Orient for six
Dean Bowditch kick-started the rout in the 22nd minute when he poked home at the far post from a Will Grigg cross, before Rob Hall added a second two minutes later with a cross-shot that sailed through a crowded penalty area and into the net.
Grigg netted a third, and his 21st of the campaign, from the penalty spot after Dele Alli was brought down under pressure from Chris Dagnall.
Hall grabbed his second before half-time with a long-range strike, and then coolly slotted in his third just before the hour to complete his first professional hat-trick.
Jay Simpson’s 69th-minute strike from the edge of the area was merely a consolation for Orient before Alli added a stunning sixth for the Dons nine minutes from time, curling in a shot off the post.
