MK Dons warmed up for their play-off challenge with a victory over Oldham.
Angelo Balanta put the visitors in front with a cool finish following Adam Clayton's pass, which deflected off of Carl Winchester and into his path.
Winchester levelled with a long-range finish for his first senior goal, before 18-year-old Keanu Marsh-Brown fired home the winner from 20 yards.
Oldham manager Paul Dickov made a late substitute appearance to end his playing career at the age of 38.
Oldham Athletic player-manager Paul Dickov told BBC Radio Manchester:
"It was good to get on the pitch but bitterly disappointed with the result.
"I didn't want to end the season on a negative note, but I just said we all have to learn.
"When we try to do things we're not so good at individually and as a team we're average and our league position shows that."
