CJ Hamilton's first-half strike sealed back-to-back League Two wins for Mansfield for the first time this season as they beat Port Vale.
The visitors also ended the game with 10 men when Manny Oyeleke was shown a second yellow card on 64 minutes.
A poor first half burst into life on 41 minutes thanks to Hamilton.
He ran into the box on the right from Hayden White's pass and sent a powerful shot flashing across Scott Brown into the far corner.
Hamilton had come the closest to a goal on 16 minutes from a similar position when his shot came back off post, a minute after Jacob Mellis had fired into the side netting from 18 yards.
Tyler Walker almost made it 2-0 just after half-time, but Brown blocked his close range backheel from Craig Davies' low cross.
Once Oyeleke had been dismissed, Stags should have had a second on 82 when keeper Brown slipped and gifted the ball to Danny Rose, but he managed to block Rose's finish and then saw Tyler Walker lift his follow-up over.
