Sheffield Wednesday kept up their promotion push with a solid victory over Oldham.
The Latics had the better of the opening half with Dean Furman and Shefki Kuqi both going close.
Home forward Robbie Simpson twice forced Owls keeper Stephen Bywater into action before David Prutton lashed home for the visitors after a neat turn.
Simpson fouled Sanchez Watt in the area and Ryan Lowe expertly despatched the penalty to seal the win.
VIEWS FROM THE DRESSING ROOM
Oldham manager Paul Dickov told BBC Radio Manchester:
"I'm delighted with our players today - the application, attitude work-rate and some of the football we played was excellent.
"The players feel deep down as if they should have got something from the game today.
"Robbie Simpson wants to stay. We definitely want him to stay. He wants to be here and we love having him."
Sheffield Wednesday manager Gary Megson told BBC Radio Sheffield:
"I am absolutely delighted because this was always going to be a difficult game.
"They are well organised and have a right good go. We've got 4,000 people here and we have a tendency to let them down but today we've not done that.
"It was a bit of a battle and a scrap in the first half, as you would expect but we've come away from home, kept a clean sheet and won 2-0."
