Ryan Sweeney made up for his error for the Argyle opener with the equaliser just before half-time.
Here are our player ratings from the game . . .
9. OLIVER IROW 7
The Spurs youngster is starting to get to grips with the more physical side of League One. Forced a good save from the home keeper before Stags levelled, having almost been wiped out by a nasty challenge before that. But showed some increasingly good aggression of his own to go wth his silky skills and confident shooting. Photo: Chris Holloway
10. RHYS OATES 6
Tried his best but was well marshalled by Plymouth, who did not allow him room to cause them issues. Worryingly limped off with nine minutes left to be replaced by Kyle Knoyle. Photo: Chris Holloway
11. LUKE BOLTON 7
Decent display by a player well short on game time and full fitness. Made one crucial first half challenge to tigerishly win the ball in his own box as the powerful Pepple shaped to make it 2-0. Withdrwn at half-time. Photo: PAUL ELLIS
12. JON RUSSELL 7
A half-time sub for Aaron Lewis, Russell again fitted in very well. Was always available and his size gave Stags a greater threat at set pieces. Photo: Chris Holloway
