Dean Lewington's own goal has given Leyton Orient a slender 1-0 half-time lead away to MK Dons in a first-round Capital One Cup affair tonight.
Dons thumped their London counterparts 6-1 in one of their League One meetings last season to bring a narrow psychological edge into tonight's affair.
It was the hosts who looked the more likely to score early on, and Carl Baker's rasping effort was tipped away by Alex Cisak - who conceded those six last term - to maintain parity for the now-League Two side.
Mathieu Baudry headed over for Orient on the 10-minute mark, before Baker drilled narrowly wide midway through the half as both sides struggled for clear chances.
The breakthrough came on 37 minutes when Lewington's botched clearance from a Dean Cox cross deceived goalkeeper Cody Cropper and it was enough for a half-time lead.
