Charlie Kelman scored two goals in two second-half minutes to boost Leyton Orient's play-off challenge with a 3-1 win at relegation threatened Crawley.
Armando Junior Quitirna gave the hosts the lead four minutes after the break, but Kelman's double settled the issue before Jamie Donley added insurance in stoppage time as the O's produced a dominant second-half display.
Richie Wellens' men are now three points off the play-offs while Crawley, after three successive defeats, are six points from safety with four games left.
Crawley boss Scott Lindsey went into the clash appealing for everyone to stay connected as "battering the players" would not help the "huge task" of trying to avoid relegation.
The Red Devils gave a league debut to keeper Luke Hutchinson, signed on an emergency seven-day loan from Bolton, and he was called into action after 17 minutes when he saved a shot from Kelman with his legs.
Crawley threatened when Jeremy Kelly's ball over the top found Kamari Doyle and he drilled an angled shot narrowly wide, and Kelman headed over at the other end shortly before the break.
The hosts broke the deadlock four minutes into the restart when Quitirna kept his cool from the penalty spot after defender Sean Clare was penalised for a challenge on Toby Mullarkey.
But Orient turned things around immediately with two goals in the space of two minutes through top scorer Kelman to extend his league tally to 19 for the season.
After levelling by firing ed keeper Hutchinson, Kelman, on loan from QPR, converted a penalty after handball by Mullarkey.
The O's threatened again when captain Omar Beckles narrowly missed a cross to the far post by substitute Dan Agyei.
Donley put the gloss on Orient's win in the first minute of stoppage time with a simple finish following a mistake by Hutchinson, and the O's now boast five wins from their past seven games.
