Rotherham manager Ronnie Moore admitted neither side had played well enough to win the game after the Millers secured a play-off place with a goalless draw at home to Crewe.
It was mainly one-way traffic in the first half as the visitors made all the running, while both sides struggled to create chances after the break amid dreadful conditions following a torrential downpour.
"It's nice to be in the play-offs," said Moore. "Although we would have liked to have done it the other way. We're in with a chance now but we've certainly got to start putting the ball in the back of the net."
He added: "That's four clean sheets on the trot, but we haven't created enough to win the game.
"Scoring goals has been a concern all season because if one man doesn't score we struggle and it's important that we start scoring because we have some crucial games coming up.
"We were playing at home and I don't like to see our keeper making too many saves, but he has had too many to make.
"We had a little bit of luck, but I don't think either side played well enough to win the game," he added.
