Veteran striker Gareth Ainsworth grabbed the only goal of the game for Wycombe against Rotherham at Adams Park to nudge his side closer to top spot in npower League Two.
On a day which saw leaders Chesterfield fight out a stalemate at Shrewsbury, 37-year-old Ainsworth pounced with a 28th minute strike to sink the third-placed Millers and move Wycombe five points clear in second.
Shrewsbury's gutsy draw kept them fourth while Ainsworth's old club Port Vale failed to gatecrash the automatic promotion places as they had Gareth Owen sent off early and slumped to a 1-0 home defeat by Cheltenham.
Fellow play-off hopefuls Crewe also failed to seize the chance to put pressure on the sides immediately above them as they were edged out 3-2 at Aldershot. The Railwaymen twice led through Danny Shelley and Clayton Donaldson only to be pegged back on each occasion, first by Wade Small then by Peter Vincent midway through the second half.
Aldershot clinched victory in injury time when Crewe goalkeeper Rhys Evans was sent off for hauling down Shots striker Jermaine McGlashan, and Luke Guttridge fired the winner from the resulting free-kick.
In a thrilling battle at the foot of the table, Ashley Grimes struck a hat-trick for bottom side Lincoln City as they boosted their survival hopes with a 4-3 win at Stockport. Grimes opened the scoring after five minutes and completed his hat-trick on 65 to put the Red Imps 4-2 up. A late own goal from Adam Watts frayed nerves but the visitors hung on for victory.
In their first game since the tragic death of their midfielder Richard Butcher, Macclesfield came through an emotional afternoon to draw 1-1 at home to Barnet, Colin Daniel cancelling out Izale McLeod's 55th minute penalty.
