Louis Barry scored a hat-trick as Posh were beaten 3-1 by promotion-chasing Stockport County at Edgeley Park.
Peterborough United took the lead at Edgeley Park, but were unable to sustain that early momentum and were ultimately beaten 3-1 by Stockport County, who look set for the end of season play-offs.
Harry Leonard had fired Posh in front after excellent work from arguably the best player on the pitch in green, youngster Bolu Shofowoke, but Barry levelled and then scored two identical strikes after the break.
It was a game full of chances at both ends with Alex Bass producing an excellent first half stop to deny Stokes while Kyrell Lisbie was denied three times by Hatters shot-stopper Addai.
The first chance of the game fell to Lisbie, who forced Addai into an uncomfortable stop before Bass made his first save of the afternoon, keeping out Sidibeh before Stokes fired wide.
The deadlock was broken on 12 minutes, Mills' cross-field pass picked out Shofowoke and he did brilliantly to pull the ball back for LEONARD who made no mistake from 10 yards.
The home side got themselves level on 27 minutes as BARRY found the bottom corner after good work from the quick Sidibeh down the right hand side.
Bass produced a fine save to keep out Stokes on 37 minutes before the goalkeeper did well to keep out Stokes moments later. Two minutes after the re-start, Stockport made it 2-1, BARRY cutting inside and finding the corner.
Lisbie should have levelled on 53 minutes as the ball cannoned into his path, but Addai did well to make himself big to smother. Mills saw a shot pushed around the post after Garbett's free-kick hit the wall.
Barry was denied a hat-trick by Bass just after the hour mark before the winger did complete his treble, a carbon-copy of his second goal as BARRY was allowed to get the ball onto his favoured foot.
On 66 minutes, Lisbie was denied again by Addai before the same Posh player dragged a shot wide of the post. Kamara fired wide and Wootton headed over as both sides traded additional efforts before the full time whistle.
