Darren Patterson maintains slim play-off hopes for Rotherham after his troops saw off AFC Wimbledon 2-1 at Kingsmeadow on Good Friday.
Sam Hoskins netted the winner within moments of coming on as an 81st-minute substitute, with the Dons almost earning a point after Luke Moore cancelled out Ben Pringle's first-half opener.
The win put the Millers up into 10th, six points off the League Two play-offs, with further victories in their remaining five fixtures effectively required for them to finish in the top seven come May.
Caretaker boss Patterson said: "Everything is to play for in the final few games now and I think if we can keep playing like we did in the first half here then I am confident we will do well.
"I thought some of the football in the first half was fantastic. I wrote in my notes that we knew AFC Wimbledon were a good passing team and they would look to play it, and we responded well to them.
"It was a fantastic first-half performance and I don't know how we have gone in only one goal ahead. AFC Wimbledon responded really well to their credit and the second half was real end-to-end stuff."
