Well, that was entertaining, if somewhat chaotic.
That's us for this match, but join us at 14:15 BST as the men's sides face off, while at the same time Welsh Fire take on London Spirit in Cardiff.
Match Hero Kathryn Bryce: "It was a stressful end, it is never calm when you've got a runner out there! Nobody ever practices it so it is all a bit of entertainment for the end.
"We had a couple of tough games to start with the rain and close losses, but we know we are building something and wanted a couple of strong performances to finish off the tournament.
"Sophie [Ecclestone] is such a big player for us and her to go down was a loss so to take more responsibility on my shoulders was great."
Well, the Originals took the difficult path to that low target set by the Superchargers, regularly losing wickets. But it was always going to be a challenge to defend 107, even if it took the penultimate ball to reach it.
It's a blow to the Superchargers' hopes of topping the table, they now look set to play in the eliminator for a place in the final next Sunday. Originals, meanwhile, move to fifth but were already out of contention for the knock-out stages.
