The Millers bounced back in the right way after the midweek defeat in the F.A. Cup.
"Crewe had a really good chance in the first half when Jamie made a wonderful save but after that I cannot really remember them having another opportunity.
"It was an absolutely fantastic performance from the lads and a great comeback from the second half display at York."
There were changes to the team from the last outing, one being John Mullins move to centre half.
Ronnie saying,"Johnny was fantastic. It was nothing new to him because he played nearly a full season at Stockport at centre half in League One. I thought that the back four when they had to be were very solid and they couldn't handle Marcus Marshall in the first half.
"It was a pity the penalty didn't go in but to be fair to the lad it was a very good save."
