Wrexham strengthened their promotion bid with a comfortable 3-1 win at Grimsby.

Andy Cannon led the way with a first-half double and Paul Mullin also scored in a one-sided clash that moved Wrexham three points off top spot.

Substitute Arthur Gnahoua snatched a late consolation for the home side.

Wrexham opened the scoring in the sixth minute when Cannon fired low into the corner with his right foot from 20 yards.

Tom O’Connor almost produced a carbon copy moments later, but a second goal did arrive through Cannon’s tidy finish in the 36th minute.

Mullin grabbed a third in the 42nd minute with a left-footed snap-shot which left Grimsby goalkeeper Harvey Cartwright stranded.

With the damage already done, genuine chances were few and far between after the restart, before Gnahoua made his mark in a late cameo.

He cut inside and beat goalkeeper Arthur Okonkwo with a left-footed drive, but the strike was too little, too late for Grimsby.
