It was another afternoon to remember for Grant McCann's side as they maintained their fine record at Blundell Park. A first half brace from Jordan Gibson sandwiched a Luke Molyneux goal against opponents who played the entire second half a man light.
The contest was barely two minutes old when Rovers burst into life and took the lead. Gibson was put through by Molyneux's piercing ball and after rounding goalkeeper Jackson Smith he found the net at the second attempt from a few yards out, after an initial block on the line by a backtracking defender.
Rovers almost doubled the lead minutes later but Billy Sharp blazed over from just a few yards out after being picked out by Brandon Fleming's centre.
They didn't have to wait too long though. Molyneux made it 2-0 after Jamie Sterry ran unopposed down the right flank and picked out the winger who provided a fine finish into the bottom left corner. Rovers were in rampant mood and Gibson's fine third just before the interval was reward for constant stream of attacks. The hosts' task was made even tougher in the aftermath of the goal when Harvey Rodgers was sent off for dissent.
That made the second half almost a non-event with the game effectively won by half-time. Rovers threatened to add to their tally but couldn't get a fourth as they return down the M180 with a comfortable win.
Here's how we rated the Rovers' players:

9. Jordan Gibson 9
Stellar afternoon as he returned to the starting XI and more than earned it. Scored twice in the first half and had the away end serenading him thereafter. Star man. Photo: Andrew Roe/AHPIX LTD

10. Billy Sharp 7
Should have scored early on but somehow blazed over. Hold-up play was good and caused problems for Grimsby's frazzled backline. Photo: Andrew Roe/AHPIX LTD

11. Luke Molyneux 9
A welcome return to the side and capped it with a fine goal to make it 2-0. Had his marker on toast at times and has rediscovered that livewire streak that makes him one of the best players in the league. Photo: Andrew Roe/AHPIX LTD

12. Josh Emmanuel 6
Came on for Sterry for the final quarter, against his former club, and did okay as he got forward plenty and got involved. Photo: Andrew Roe/AHPIX LTD
