Will Boyle's first-half header proved the difference as Shrewsbury Town beat Oldham Athletic 1-0, denting the visitors' play-off hopes with four games of the season remaining.
The defeat left Latics four points off the pace, with chances created and squandered by Kane Drummond, Joe Garner and Fabio Jalo all going begging during an improved second half.
Hosts Set the Tone
Shrewsbury started the stronger of the two sides, with Taylor Perry and Iwan Morgan threatening early. Bradley Ihionvien scuffed an effort at the keeper before Kai Payne was unable to find the target midway through the half.
