Billy Bodin's eighth goal of the season secured Bristol Rovers a 2-1 victory over League One's bottom club Plymouth at the Memorial Stadium.
The hosts took a 22nd-minute lead when a low cross from the right by Ellis Harrison found Rory Gaffney in yards of space inside the box and the striker fired home from 12 yards.
But Argyle started the second half well and equalised in the 52nd minute when former Rovers striker Nathan Blissett found the top corner with a well-taken right-foot shot from an angle.
The winner came after 62 minutes when Gaffney's low cross from the left was met by Bodin with a fierce first-time shot with his left foot that gave Kyle Letheren no chance.
Plymouth were reduced to 10 men two minutes later when Gary Miller was shown a straight red card for a foul on Joe Partington.
Rovers created most of the chances and Letheren had to make flying saves from Liam Sercombe twice and Harrison, while substitute Tom Nichols hit a post.
