United bounced back from the surprise defeat to Co Tyrone to thrash Revo Express 8-0 in Ballmoney.
James Wilson got the ball rolling with a great finish from the left-hand edge of the box and the promising striker doubled the lead after fine work and a neat pass by Liam Grimshaw.
Sam Byrne added a third before the break when pouncing on the rebound after his initial header from a Wilson cross bounced back off the bar.
Josh Harrop took centre stage in the second half, smashing a couple of similar strikes to make it 4-0 before converting another smart finish to notch his hat-trick.
Substitute Ashley Fletcher got in on the act by making the most of a one-on-one opportunity and a long-range strike by midfielder Harrop, for his fourth, rounded things off on a productive evening.
The Reds can still qualify for the knockout stages with a sizeable win in the final group game against Ichifuna if other results are favourable.
"The boys recovered well, they weren't the strongest opposition tonight but all the things we were working on in training and working on came out and we got some good goals and good finishes on the end of some good moves," coach Paul McGuinness told MUTV.
"Josh got four, he could have got seven or eight. He took his goals nicely and he'll be pleased with himself.
"I really don't know what to expect from Ichifuna, it's hard to tell. Theyll be energetic and excited to play us and we'll have to have the same approach as we did tonight. If we want to go through, we need to score goals and win the game."
United: Gollini (O'Hara); McConnell, Rowley, McNair, Grimshaw; Weir (Fletcher), Harrop, Rothwell, Pearson (Willock); Byrne (Pereira), Wilson (Redmond).
