Bury climbed back into the automatic promotion places with a hard-fought 1-0 win over derby rivals Rochdale.
Former Bury loanee Chris O'Grady missed a golden opportunity to put League Two leaders Dale into a late lead.
And Ryan Lowe made him pay moments later, claiming a 78th-minute winner with his 11th goal of the season.
That halted Dale's 11-match unbeaten run and sent the Shakers back into third, although Dale remain seven points clear.
Bury edged a frenetic first half, in which the best chance fell to home skipper Stephen Dawson.
Lowe and strike partner Andy Morrell combined to find Dawson, whose first-time effort was parried by Dale goalkeeper Frank Fielding.
Morrell had earlier fired wide after a Brian Barry-Murphy free-kick hit the wall, and in reply, Jason Taylor and O'Grady hit long-range efforts well off target.
The hosts remained on top after the break, with Morrell hitting a 20-yard effort narrowly wide before Efe Sodje's header was headed off the line by Will Atkinson.
Dale began to find space in attack and Craig Dawson's header was saved by Wayne Brown.
Dave Buchanan was then robbed by Dale's new loan signing Tope Obadeyi, who squared for O'Grady to scuff wide of an open goal under pressure from Sodje.
Nathan Stanton's clearance was then charged down by Dave Worrall and the loose ball fell kindly for Lowe to tuck past Fielding from 16 yards and secure bragging rights for Bury.
