A review of Sunday's action in Sky Bet League One.
Alex Jones' first-half goal was all that Port Vale needed to see off MK Dons 1-0 and end a winless run away from home that stretched back to April.
AFC Wimbledon's 3-1 win at Oxford earlier in the day saw Neal Ardley's side go above MK Dons for the first time in the EFL and Karl Robinson's day got even worse when Jones netted the winner.
Neal Ardley's AFC Wimbledon had failed to win in 12 previous attempts against Oxford, but a stunning first half saw them three goals up at the break.
Tom Elliott headed the visitors in front from close range at a 20th-minute corner after Darius Charles nodded the ball back from the far post.
Charles scored a spectacular second goal in the 42nd minute, curling the ball into the top corner from 20 yards as Oxford's players protested about what looked like a dangerous tackle on Wes Thomas by Dean Parrett.
Oxford's players were still rattled by that controversial decision when Andy Barcham ran through the middle in first-half stoppage-time and slotted home Jake Reeves' pass under goalkeeper Simon Eastwood.
The hosts pulled a goal back four minutes into the second half when Charles turned Chris Maguire's cross into his own net.
