Rotherham boss Ronnie Moore admitted he issued some "strong words" to his team at half-time before they went on to beat Lincoln 1-0.
Adam Le Fondre's second-half goal took the Millers through to the next round of the Johnstone's Paint Trophy, but only after some harsh words from the manager.
He said: "It was a bit sloppy in the first half, but in the second we upped the tempo and passed it and when we did that I thought there was only going to be one winner.
"It was like a five-a-side before the break. We were playing let them have it and then we'll have it, but we wanted to keep our winning run going, so we had one or two strong words at half time and upped the tempo.
"We started getting the ball forward quicker, passing and doing the right things. Probably the best chance they had was when our skipper Ryan Cresswell chested the ball back to his own keeper."
