Plymouth 1-0 Bradford
Juvhel Tsoumou's early strike was the difference between Plymouth and Bradford in a tight battle between the League Two strugglers.
Preston loanee Tsoumou nodded Plymouth in front at the back post from Paul Wotton's free-kick.
Robbie Williams' shot hit a Bradford post before striking Bantams keeper Matt Duke and falling to safety.
Jake Cole made a double save from Guy Branston and Lee Bullock's follow-up to preserve Argyle's lead.
And Duke pulled off a stunning stop late on to keep out Wooton's piledriver.
Macclesfield's defeat at Gillingham means both sides are now four points clear of the relegation zone.
VIEWS FROM THE DRESSING ROOM
Plymouth Argyle manager Carl Fletcher tells BBC Radio Devon:
"It could have been a lot easier for all us in the last 10 minutes than it was, but we'll take 1-0.
"Really delighted with the lads, I'm proud of them. There's so much pressure on us at the moment.
"It's going to be a really tough game next week, but we'll go into it full of confidence."
