League Two leaders Rochdale ran riot against promotion rivals Rotherham, triumphing 4-0 at Spotland.
Chris Dagnall's close-range strike gave them an early lead but Rotherham's Adam Le Fondre had a header cleared off the line by Tom Kennedy before Jamie Green's own goal knocked the stuffing out of the Millers. Two goals in three minutes from Craig Dawson and Chris O'Grady then clinched the victory.
Notts County boosted their play-off bid as Jamie Clapham's 18th-minute header saw off Macclesfield 1-0.
Bottom club Darlington and fellow strugglers Cheltenham were both beaten at home. Ryan Green's solitary goal saw Hereford past the Robins despite the sending-off of James McQuilken while Tadgh Purcell's early goal was in vain as the Quakers succumbed to Port Vale's second-half comeback, Doug Loft's 20-yard volley levelling the scores before Louis Dodds and Lewis Haldane sealed the points.
Elsewhere, defender Anthony Charles' fine left-footed strike earned Aldershot a 1-0 win over Bradford while Torquay drew 0-0 with Dagenham and Redbridge.
