Crawley came from a goal down to beat Rotherham and move level on points with Southend at the top of League Two.
Brett Williams gave the hosts the lead when he latched onto the end of Conrad Logan's long goal-kick and guided the ball past the onrushing Scott Shearer.
But after the break the visitors hit back when Tyrone Barnett's powerful drive flew past Logan.
The turnaround was complete when Jon-Paul Pittman's pull-back was fired in by Josh Simpson at the second attempt.
The Red Devils are now unbeaten in 11 league games.
VIEWS FROM THE DRESSING ROOM
Rotherham boss Andy Scott told BBC Radio Sheffield:
"The better side has lost, but that's what happens when you play the top teams. You've got to be concentrating for 100% of the time and we did it for 95%.
"We didn't start the second half well, the first five or six minutes and then we conceded the goal, but apart from that we've had numerous chances. I lost count of the number of very good chances we've had, we haven't hit the target enough and they've probably had two or three chances.
"We pick ourselves up but we've got to be more ruthless in terms of making sure we do our jobs all the time and not think that we're too clever."
Crawley manager Steve Evans told BBC Sussex:
"We should have been out of sight in the first half. We looked as if we'd never played together. I couldn't repeat publicly what I said at half-time.
"There was a few that took a bashing. They gave us a reaction in the second half. We were a different side and should have won more comfortably that we did.
"I shouldn't have to have that half-time chat. But it's another win and an important three points for us."
