Tranmere climbed back to the top of npower League One with a 2-0 win at Hartlepool.
Andy Robinson's 79th-minute penalty sent Rovers on their way to a first win in four and means they leapfrog Sheffield United and Stevenage at the summit. Managerless Pool, watched by prospective boss Phil Brown, remain bottom after making it 15 games without a win.
After a quiet first half, Pools should have been ahead just 14 seconds into the second, Jon Franks put in on goal, but keeper Owain Fon Williams saved well.
Home goalkeeper Scott Flinders then made three impressive stops to deny Andy Robinson, Adam McGurk and James Wallace before he was beaten. Hartley tripped Wallace in the area and Robinson made no mistake from the spot.
And in injury time, substitute Cole Stockton ran across the Pools defence and curled a fine effort around Flinders.
Ryan Lowe scored the only goal as MK Dons secured their second successive win with a narrow 1-0 victory over Leyton Orient.
The 34-year-old striker netted his second goal of the season just before half-time to condemn Orient to their fourth straight defeat.
Milton Keynes dominated the first half and Luke Chadwick and Dean Bowditch were both denied one-on-one by keeper Ryan Allsopp, who also spilled a 25-yard drive from Angelo Balanta against the post.
Lowe then had a fierce shot pushed over the bar by Allsopp before the veteran striker put the Dons ahead four minutes before the break, tapping in Bowditch's low cross from close range.
Orient improved after the interval and David Mooney was denied three times by keeper David Martin within the first 10 minutes of the second half. The Dons regained control in the closing stages and Chadwick had a low shot brilliantly saved by Allsopp before Lowe fired a snap-shot narrowly wide.
