Peterborough 1 Doncaster Rovers 2: Play-offs in view after Oster hits late winner

Bottom-of-the-table Peterborough, bidding for their third consecutive victory, enjoyed the better of the first half and deservedly took the lead 10 minutes into the second half when Charlie Lee headed home.

But Rovers, who are now unbeaten in five games and closing in on the top six, levelled 12 minutes later.

Martin Woods, making his 100th league start, saw his cross partially cleared by Craig Morgan and Gareth Roberts thumped home a 20-yard volley.

Rovers then won it at the death – securing their first success at London Road for 20 years – when Oster tapped home Billy Sharp's cross from close range to score for the first time since February 17 2009.

Posh flew out of the traps, with Mark Little firing over from the edge of the box and Scott Griffiths having his volley blocked by Shelton Martis inside eight minutes.

Lee then forced Rovers goalkeeper Neil Sullivan into a save to keep out his 25-yard shot. Rovers were still to find their range as Oster fired an effort wide with Posh then creating two excellent openings.

First Gabriel Zakuani headed a Torres corner wide before the latter was denied by Sullivan from the edge of the box.

Peterborough came close yet again to opening the scoring in the 50th minute but Sullivan pulled off another save to keep out Morgan's header from a Tommy Rowe free-kick.

But Lee was not to be denied shortly afterwards when he finally made the breakthrough.

Mackail-Smith was denied by Sullivan while Rowe and Exodus Geohaghon failed to hit the target before Roberts's stunner.

Gabriel Zakuani (Posh) and Jay Emmanuel-Thomas and Woods (Doncaster) came close to late winners before Oster scored.
