Against Manchester, Solihull had taken charge with a spectacular display in the third period, scoring five goals without reply - from Arthur Davies, Ben Greenhill, Nick Beard, Jordan Elliot and Jake Vincent.
Teams taking their turn on playing two games in a day often suffer in the second outing - but not Solihull. They went 6-5 down at the start of the last period against Cheltenham when Albert Tarres converted a man-up opportunity. But Cheltenham offences then gave the Midlanders a sniff of victory - and they grabbed it with both hands. Peter Farkas's penalty levelled it at 6-6 before Jordan Elliot netted the winner from a man-up chance.
Lancaster's Tom Curwen, the men's Super 5s top marksman once again this season, took his tally to 20 with four more in a 12-5 success against Caledonia. Cheltenham's defeat, combined with today's battling efforts by Lancaster and Solihull, have put a very different complexion on the struggle for the championship. Before today, Cheltenham were hot favourites. Now, a third title is no longer a formality.
