Mooney brilliantly run out by Healy; Wolvaardt runs out Monaghan superbly from the boundary
Superchargers post 127-4 - Heath 57 off 34 balls
Spirit have now won one, lost one
Superchargers have lost both their games
That's it from us - well, for about 10 minutes anyway.
We'll be back to bring you the men's game from Headingley from 14:15 BST as the Superchargers aim to double up on their home ground. You can watch coverage of that live on BBC Two now, with radio commentary online.
Elsewhere, Oval Invincibles are playing Southern Brave in the women's competition. Radio commentary of that is on BBC Radio 5 Sports Extra from 14:20 BST.
A first win of the campaign then for the Northern Superchargers. They'll be very glad of that, especially after a losing streak to end the tournament last year too.
For London Spirit, though, it is two defeats from two and with a shortened group stage this year after the Commonwealth Games, they might need to win out from here to reach the Eliminator.
Northern Superchargers captain Hollie Armitage, speaking on Sky Sports: "I'm absolutely chuffed, I'm really proud of the girls. I think the way that they held their nerve at the end was absolutely phenomenal.
"After the first ball [of the last five], I got a bit nervous but then ADR (Alice Davidson-Richards) is someone you can really trust what she's doing, and she trusts herself as well. I had all faith in her.
"Bess Heath really set the tone today, when she gets her reverse switch-hits out and they go for four... She's an outstanding player, someone to look out for in the future."
Match Hero Bess Heath to Sky Sports: "I talked with Laura Wolvaardt about building a partnership and it was decided for me to take it on and Wolfie to be the anchor. So it was a case of trying to hit the boundaries or if not find the singles in and around it.
"There wasn't too much spin so for me it was about looking down the ground. But it would skid on nicely so it was nice to bat on.
"Another 15-20 runs we would have been right on the money so we knew we had a job to do in the field and I thought we executed that very well.
"Alice Davidson-Richards bowled extremely well under pressure, she is very good at that position. As a group we do well under pressure, we thrive off it."
Lucy Higham: 1-28 from 20 balls
Beth Langston: 0-23 from 20 balls
Linsey Smith: 1-24 from 20 balls
Jenny Gunn: 0-18 from 10 balls
Alice Davidson-Richards: 2-20 from 20 balls
Katie Levick: 1-8 from 10 balls
What a win for the Superchargers and this was a huge moment. Beth Mooney run out after a big of brilliance from Alyssa Healy. Even when she isn't in the runs, she's producing game-changing moments!

What a win this is. London Spirit had a good start with that 48-run stand off 36 balls and it was looking rather easy. But those three wickets changed things around.
Credit to the Superchargers for pegging this back. The bowlers were absolutely fabulous, bowling with a lot of discipline.
Spirit 122-7
Natasha Wraith can only heave it up to long on for a single. It's a big win for the Northern Superchargers by five runs.
London Spirit will feel like that is one that has got away.
Wraith comes in with one ball left, six needed for a tie...

Listen to the crowd roar! That should secure victory for the Superchargers. The London Spirit captain has to go!
Dean c Heath b Davidson-Richards 5 (Spirit 121-7)
Caught in the covers, that surely does it for the Superchargers!?
Charlie Dean tried to hit over the covers again, with nobody back, but couldn't get enough on it and Bess Heath takes the catch.

This is one of the best games of the Hundred so far. Men or women.
Need 7 more runs to win
Lifted down to long on again and they can't get back for a second. Good from Davidson-Richards.

How massive is having that extra fielder inside the circle? It could cost Superchargers the game.
Need 8 more runs to win
Single down to long on. Luff back on strike.

Silence inside Headingley with that boundary from Charlie Dean!
Need 9 more runs to win
Thumped over the off side for four by Dean! That extra fielder being up has cost the Superchargers.
Need 13 more runs to win
A wide helps the Spirit before they do decide to take a single.
That brings Charlie Dean on strike with five balls to go.
They've not made the cut-off time so an extra fielder comes into the ring.

What an amazing bit of fielding! A direct hit from the boundary!
That is incredible!
Monaghan run out (Wolvaardt) 4 (Spirit 113-6)
Fantastic from Laura Wolvaardt! A direct hit from the deep!
They were coming back for two though so Luff will still be on strike.
