Plymouth Argyle need four more points to secure their Football League survival after they beat Aldershot at Home Park to go six games unbeaten.
Alex MacDonald's deflected 14th-minute strike separated the sides as it looped over Aldershot keeper Jamie Young.
The Shots then laid siege to Argyle's goal as Peter Vincenti saw a first-half header saved by Romain Larrieu.
In the second half Ben Herd had a goal ruled out for offside while Danny Hylton hit the post.
VIEWS FROM THE DRESSING ROOM
Plymouth Argyle manager Carl Fletcher told BBC Radio Devon:
"We couldn't kick it, pass it, we didn't play well but I don't care. We got the result and that's the main thing.
"If anyone questions my lads' desire, they'll have me to answer to.
"Another clean sheet, it's great for the defenders and the goalie. You keep clean sheets, you're going to win games.
"The lads knew it was going to be tough; winning your headers, sticking your foot out and putting your body on the line and they did that great today."
Aldershot manager Dean Holdsworth told BBC Surrey:
"That's the bitterness of football sometimes that you don't get what you deserve.
"We've absolutely dominated that game. We've had the ball in the back of the net twice, we've hit the post twice. I've just said to the players, if we play like that every week we're gonna be a good side.
"I thought the play-offs would be a long shot for us, but with the performance of the players today they've got every right to feel a little down.
"It was like the Alamo. I wish we wee playing tomorrow. We're like a wounded animal, we want to snap back, but we will do".
