Troy Parrott was among the goals as MK Dons moved into the top two in League One for the first time this season after a 2-1 win over rock-bottom Crewe at Stadium MK.
The Republic of Ireland striker set the Dons on their way to an eighth win in nine matches before international team-mate Conor Coventry doubled the lead before half-time, leapfrogging Liam Manning's men above Rotherham into the top two.
Spurs loanee Parrott was the beneficiary of a sublime pass from Dean Lewington which he controlled and lifted over helpless Alex keeper Dave Richards, before Coventry made it 2-0 when he glided through the Crewe midfield and slammed home his first Dons goal.
Fellow Ireland striker Will Keane was also among the goals as table-toppers Wigan Athletic beat Accrington Stanley 3-0.
Wigan regained leadership of the table for the first time since January in emphatic style as Keane sealed the win to make it 3-0, following up to tap home after Accrington goalkeeper Toby Savin dropped a free-kick at his feet.
Elsewhere, Kieran Sadlier's penalty with 14 minutes left gave Bolton a 1-1 draw at home against Portsmouth, who had gone in front five minutes into the second half through Aiden O’Brien.
In the Championship, Jonson Clarke-Harris headed in a late equaliser for Peterborough as the Championship's bottom club held promotion-chasing Luton to a 1-1 draw at London Road.
Sheffield United boosted their Championship play-off hopes with a 1-0 victory over QPR following an early goal from Oliver Norwood, while Joel Piroe scored his 18th goal of the season in all competitions as Swansea secured a 1-0 win against Millwall at The Den.
Cameron Archer's first-half strike fired Preston to a hard-fought 1-0 win over local rivals Blackpool at Deepdale, and Reading moved eight points clear of the Championship relegation zone with a hard-fought 2-1 home victory over Stoke.
