Paul Warne was again the hero of the hour as Rotherham United claimed an impressive 2-1 victory over last year's play-off semi finalists Rochdale. Adam Le Fondre had scored the opener against his former club before Chris Dagnall equalised on the stroke of half time.
The Millers dominated the first half, creating five chances in the opening ten minutes. Warne's low strike was tipped around the post by Kenny Arthur, who also saved a Nick Fenton header from the resulting corner. Tom Pope then saw an effort blocked, before his diving header went wide following good work down the right by Dale Tonge.
Le Fondre then fired wide from the angle, before anticipating a mix up in the Dale defence, but Arthur was quick off his line to prevent his former teammate.
The Millers new boy thought he'd put his new club in front on 14 minutes. The 22- year-old chased down goalkeeper Arthur, and stroked home after he blocked his clearance, but the referee's assistant was penalised the forward for handball
Rochdale did mount an attack 25 minutes in, Chris Dagnall and Will Buckley both having shots from distance saved by Andy Warrington before the latter cut in and curled an effort wide.
The breakthrough came on forty two minutes after Stanton was booked for a foul on Warne. Nicky Law took the resulting free-kick on the right and Le Fondre rose highest to head the Millers in front.
The fourth official indicated two minutes of stoppage time, and it was just enough for Dagnall to get behind the Rotherham defence and poke the ball under Warrington to level the scores.

The Millers' spirits were certainly dampened by Dale's equaliser and they failed to dominate the second half as they did the first.
However, it was Rotherham who created the first chance, Le Fondre meeting a cross on the half volley, but he was unable to keep it down and it flew over the crossbar. At the other end Dagnall got behind the defence once again but his soft effort was saved by Warrington this time.
The winning goal came on the hour. Pope found some room on the right and his cross found Warne who got in front of his defender and beat Arthur to score his third goal of the campaign.
Law got the better of Nathan Stanton with 12 minutes left, but his cutback failed to find substitute Kevin Ellison and the ball was cleared.
There was little action in the second half, and with 10 minutes remaining Rochdale pushed for an equaliser. Adam Rundle hit a first time shot from in the area but it went high and wide of the Millers goal.
The final chance fell to ex-Miller Chris O'Grady who found space on the left, before unleashing a left footed effort that was saved by Warrington at the near post.
The referee brought an end to the game to give the Millers successive wins, and move them up to fifth in the table. Attention now turns away from the league as they prepare for the League Cup second round tie at West Bromwich Albion on Wednesday.
