There was nothing between the sides for the first two quarters, which ended all square at 3-3. Both goalkeepers - Ben Alcorn and Dylan Green - made top saves while Invicta were boosted by two terrific long-range goals from Callum Bailey.
A Joe O'Regan goal was the only score of a competitive third quarter. But after that, it was all Manchester who, in quick succession, made sure of the points with man-up goals from Andrea da Caro (2) and Joel Leighton.
Four goals in a dominant opening quarter by Jordan Elliot put Solihull on the way to a 20-7 victory over Lancaster.
Cheltenham stormed into a 3-0 lead - then 6-1 - against Invicta, an advantage that proved vital as a fiercely contested match developed. Eventually, Cheltenham triumphed 12-7, including four goals from young Tom Hunt.
