Superchargers chase 136 with one ball to spare to seal place in knockout stages
Southern Brave also progress as a result
Spirit and Manchester Originals eliminated as a result
Spirit make 135-7 with Kerr making unbeaten 60 off 32 balls
That's it from the first of today's double-header at Lord's.
Another exciting finish but Northern Superchargers got over the line and they're safely through to the knockout stages. London Spirit are out.
You can read Tom Mallows' report on that one here.
We'll be back after a short break for the men's game. Join us here for that from 18:15 BST.
Northern Superchargers' Kate Cross on Sky Sports: "Yeah [I thought I was gone], nine times out of 10 you're catching that.
"So I felt a bit for Tara because that meant that the Spirit can't qualify and you could see how disappointed she was.
"But we're just finding ways to win at the minute. So it's great to be in the Superchargers camp.
"The way that we've been bowling has been fantastic, as a unit, everyone is chipping in. Then with the bat, Phoebe [Litchfield] has been leading the charge - batting right-handed and left-handed and making it look really easy.
"We've spoken about momentum in tournaments like this. We've had a bit of a break and to get through to the eliminators is absolutely brilliant."
Match Hero Phoebe Litchfield: "I'm so glad we just got it done in the end. Georgia Wareham, Jemimah [Rodrigues] at the top and then Kate Cross at the end, it was definitely a team win.
"It has been awesome to score runs and win games. I've loved my time at Superchargers. To get into the knockouts is really exciting and I'm really keen to get back down to London and take on whoever we take on.
"It's a dream come true to play at Lord's. I remember coming here aged 10 so to be on this side is really special.
"I just do standard practice. I'm not the biggest hitter so I try and hit different pockets."
Phoebe Litchfield is the Match Hero and says it was "a dream come true" to play at Lord's and that she's glad to have come out on the winning side.
We'll have more from that interview shortly.
What a remarkable finish. Just as the Superchargers looked to have won it, they nearly threw it away.
Kate Cross could have been stumped and then really should have been caught by Tara Norris. It was a sitter.
London Spirit are now out. So, too, are Manchester Originals.
Dropped in the covers - an absolute dolly! But that does it for the Northern Superchargers!
They win and secure their place in the knockout stages. Southern Brave are now officially through as well.

Alice Davidson-Richards won't want to see this one again, though. She half-committed to a scoop shot but Sarah Glenn found a bit of extra bounce.
That surprises the batter and she ends up playing a nothing shot. The ball flicks off the glove, onto her body and loops up.
Ghosh reacts very well behind the stumps and dives forward to take the catch.
