Joe Rothwell grabbed a brace with James Wilson, Gyliano van Velzen, Jack Barmby and Kenji Gorre all doubling their tallies for the tournament. As in the opener against FC Zamora, Paul McGuinness' Reds came on strong late in the tie with Jack Rudge wrapping things up with a seventh.
Jonny Sutherland didn't have a shot to save as the Reds totally dominated but only had one goal to show for their first-half superiority with Wilson smashing into the top of the net from a Charni Ekangamene pass. The second period was one-way traffic in front of a healthy crowd as van Velzen drilled in number two after Wilson pounced on a defensive error before Rothwell followed up a great spin on the edge of the box with a smart finish.
Barmby blasted home when gifted possession by Jack Boggs but his effort was bettered by Rothwell's second - a superb strike from 25 yards out that gave the Tyrone keeper no chance. Substitute Gorre got his name on the scoresheet by tucking home after more good work by Barmby and there was still time for Rudge to find the left-hand corner of the net from the centre of the area.
United: Sutherland, Hendrie (Daehli), Blackett, Wilkinson, McCullough; Ekangamene (Rudge), Weir, Rothwell, van Velzen (Gorre), Wilson (Barmby), Lawrence (McNair).
