Chesterfield sprung into fifth place tonight courtesy of a salvo of goals on either side of half time.
Three points from their Proact match with Crawley saw them jump over local rivals Sheffield United and into the Play Off zone.
Crawley began the evening as the bottom club in League One, with just 24 points from 26 games.
They had the first attempt on goal, Anthony Wordsworth’s header was saved comfortably by Tommy Lee.
At the other end, Armand Gnanduillet hit a freekick into the wall and then had a header collected by the visiting keeper Lewis Price.
Crawley thought they had gone ahead on 17 minutes.
A Crawley corner was dropped by Lee and stabbed over the line by Izale McLeod, but the referee blew for a foul.
McLeod then claimed he’d been downed in the home box, but was waved away.
Luckless Crawley hit the bar and then went behind: Doyle adding another to his personal collection.
On 34 minutes, Doyle controlled the ball, wriggled past his marker and slotted home as low shot.
It was a craftsman’s goal coming at the right time and against the run of play.
The opener filled Chesterfield with confidence and Armand came within a whisker of adding a second before the half time whistle.
Paul Cook’s men didn’t have to wait long for to double their lead.
On 51 minutes, Jay O’Shea cut inside and left-footed a curling effort in from more than 20 yards.
Crawley immediately caved in and Doyle grabbed his second of the night.
The visitors tried to salvage some pride and almost scored, but Lee stopped Dean Morgan from close range.
And that was the end of their night, but another super evening for the Spireites and their fans.
