Liam Hearn scored his fourth hat-trick of the season as Grimsby boosted their play-off hopes by crushing lowly Bath.
Hearn slotted home from 12 yards before Bath's Andy Gallinagh steered the ball into his own net as Grimsby closed in on their sixth successive league win.
A close-range finish from Hearn made it 3-0 and he soon completed his treble, blasting home from the edge of the box.
Kiernan Hughes-Mason finished off from a Frankie Artus cross and Anthony Church's powerful shot sealed the rout.
VIEWS FROM THE DRESSING ROOM
Grimsby Town joint-manager Rob Scott told BBC Radio Humberside:
"I was sent to the stands because I asked the linesman why he gave Craig Disley offside when it was apparent he wasn't interfering with play.
"I know I get over-exhuberant at times but I'm not going to apologise for being determined to win. Like me or loathe me that's the way I am. I can't change, I've tried but it doesn't have the same effect on how I coach or effect football matches.
"I'm just disappointed that a woman's [referee Amy Fearn] got one over on me in the fact that she sent me to the stands, no warning, just straight to the stands. It isn't sexist and it would be the same if it were a man refereeing, if you're not good enough, you're not good enough.
"They'll suspend me and put me to the stands for a few games but that's just the way it is. It's the first one since I've been here and I'll try and make it my last."
