BOSS Paul Warne admitted his side had spurned a golden opportunity to press their play-off claims as their home woe continued in League One.
The Millers began their clash against Rochdale at AESSEAL New York Stadium this afternoon in fourth spot but it was the visitors, after five successive league losses, who won 1-0.
The defeat was Rotherham's fourth on their own turf this season and dropped Warne's men down to eighth place.
"This was a good opportunity to stabilise ourselves in the top six," the manager said. "It feels like another setback.
"We just didn't have enough quality in the final third and the ball just didn't drop to us."
The contest was settled by Aaron Morley's superb 42nd-minute strike as second-half pressure from the Millers failed produce an equaliser.
"They had that little bit of magic that we failed to find," Warne added. "I could come out with loads of reasons as to why I think we didn't win the game but fundamentally they bent one in from 20 yards and we didn't.
"Sometimes your substitutions work and sometimes they don't. We were desperately trying to get a goal. Had we got the first goal then the game might have taken a different path.
"They got a brilliant goal. Unfortunately we did not have anyone who could have done the same bit of magic today.
"Our performance wasn't a bad one. But for whatever reason if we don't score first at home it adds to the pressure."
