Rotherham haven’t much of a record at all on this ground - only three wins in the last 20 visits.
But the 1,600 sell-out Millers following still travelled with high expectations and they gave their favourites a great reception.
Rotherham began defending the end where their fans were and the first action was at the other end.
Ainsworth cut in from the right and struck a shot from 25 yards which had Ingham flying away to his left to save.
Blair and Walker were lively when they picked up possession but Walker’s shot from outside the area was a poor one.
Then York showed their pace on the break and, but for magnificent defending from Morgan, Rotherham might have been behind.
Blair made inroads before slipping the ball into the path of Walker, only for Morgan to time his last-ditch tackle to absolute perfection and concede a corner.
York were certainly capable of sharp incisive attacking moves and, when Rotherham were opened up, the centre from Chambers flashed right across the danger area.
Rotherham had not threatened for a while but then made a shooting opportunity. Odejayi held up possession before slipping aside to O’Connor who had a bit of space but his 25-yarder was straight at Ingham.
The home side looked in trouble when Odejayi slipped the ball beyond the defence for Ainsworth. He moved into the area but was getting squeezed for space and his effort from 12 yards was never going to beat Ingham.
Half-time: York 0 Millers 0.
Rotherham made a change at half-time, replacing Pringle with Agard.
The reshuffle in attack saw Evans switch to the right with Agard on the left, and Ainsworth took the Pringle role playing off Odejayi.
A good ball from Arnason saw Ainsworth scamper behind the defence but he was under fierce pressure from Fyfield as he prodded Then the home side had a miraculous escape.
Evans danced his way into a shooting position, drilled in an angled effort and Ainsworth somehow popped up inside the six-yard area but managed to divert the ball wide.
It had been a tight affair throughout but Rotherham had been the more threatening of the two outfits in the second half.
Arnason, who had picked up a booking, struck a rasping, low 25-yarder narrowly wide of the near post with Ingham struggling.
Two minutes from the end Chambers struck an angled chance against the outside of the near post.
