Rochdale closed to within two points of Bournemouth after hammering the Cherries 4-0 in the big game at the top of Coca-Cola League Two on Saturday.
Chris Dagnall gave Dale the lead on the stroke of half-time and the visitors ran away with the second half.
A double from Chris O'Grady and one from Simon Whaley completed the scoring, although Dale's day was soured slightly by a red card for Nathan Stanton.
Dagenham and Redbridge dropped to third after they needed a late goal from Josh Scott to secure a 1-1 draw with Port Vale, who led through Louis Dodds' 38th-minute strike.
Big-spending Notts County could also only manage a point as they were held to a 1-1 draw by Shrewsbury. It was a similar story for the Magpies as Jamie Devitt put the Shrews ahead before Graeme Lee equalised five minutes from time.
County stayed level with Rotherham on 26 points after Ronnie Moore's side made it four games without a win in a goalless draw against Aldershot, while Burton and Bury also drew a blank.
Chesterfield climbed into the top seven thanks to Scott Boden's 64th-minute strike in a 1-0 win over Barnet, who dropped to eighth.
Bradford fought back from two goals down to draw 2-2 with Macclesfield. Colin Daniel and Hamza Bencherif put the hosts in control at the break but goals from James Hanson and Steve Williams earned the Bantams a point.
Crewe moved away from the strugglers in thumping style after hammering Cheltenham 4-0, while bottom side Darlington suffered their fifth defeat in six league games at the hands of Hereford.
Darlington are now nine points off safety after Torquay beat Northampton 1-0 thanks to Chris Hargreaves' 83rd-minute header as Morecambe also pulled away from the bottom two thanks to a 3-1 win over fellow strugglers Lincoln.
