Exeter City slipped out of the play-off places in League Two after slumping to home defeat to Rotherham United.
The Millers, who had only won one game away from home going into the match, took the lead four minutes before half-time with a header from Ian Sharps.
The visitors had started the match brightly, with the lively Ben Pringle playing Alex Revell in on goal only to see his shot well saved by City keeper Artur Krysiak.
The home side hit back as top scorer Jamie Cureton brought a good save out of Andy Warrington, before Alan Gow turned and curled a 25-yard shot against the Rotherham crossbar.
It was the visitors who began to press again though as the game approached half-time and following a succession of corners Sharps headed in what proved to be the winner.
After the break, Rotherham began their time wasting tatics early in a bid to frustrate City. They also sat men behind the ball, making it difficult for the likes of Gow and Matt Oakley to create chances.
A long range effort from Gow was the closest they came to an equaliser, but Warrington saved down to his right. And although Warrington fumbled the ball, Cureton couldn't put in the rebound.
There was a late flurry of cards from referee Oliver Langford, which saw Mitchell Rose sent off for a two-footed challenge on Aaron Dawson. But, with still ten men to put behind the ball it didn't disrupt Rotherham's containment exercise too much and they hung on for the three points. It is a win that lifts Rotherham back into th play-off spots, at City's expense.
