Danny Boshell struck from 20 yards to boost Grimsby's promotion hopes, but push Mansfield closer to relegation.

The visitors took the lead when Peter Till's shot found its way through a crowd of players, but Nathan Arnold levelled with a great turn and finish.

Mansfield had chances to take the lead before Boshell fired into the top corner from 20 yards.

While Grimsby have play-off hopes, Mansfield are five points from safety and have not won at home this year.
