Beaumont (42) and Dottin (50 not out) fire Spirit to victory
Leading run-scorer Rodrigues hits 57 in Superchargers' 126-5
Northern Superchargers won toss and opted to bat

Wolvaardt 12, Rodrigues 8
That's the end of the powerplay - and you'd have to think that London Spirit will be pretty happy.
They've got the big wicket of Lauren Winfield-Hill, and they haven't allowed Superchargers to get away from them.
Good over from Deepti Sharma with just three runs and a wide coming off her second set of five. She's conceded 10 from 10 balls so far.
There was a brilliant bit of improvisation in that set from Laura Wolvaardt, as Jemimah Rodrigues slapped a filthy full toss back down the back, she did really well to jump out the way and allow the ball to go between her legs.
I know this is a ridiculous comment, but Lord's looks even more slopey than usual today. I know, that's a silly comment, but it really does.
Laura Wolvaardt picks up her second boundary with another drive. This one is a bit uppish, but it brings the same result.
Freya Davies beats the bat next up. This has been a good even start.

One of the umpires today is the rather wonderfully named Yvonne Dolphin-Cooper.
England's Freya Davies is into the attack for Spirit.
South Africa's Laura Wolvaardt is off the mark straight away with a nudge down to fine leg for a couple.
Oh, that is beautiful! Sophie Munro goes a tad too full, and Wolvaardt just leans on a drive that races to the point boundary. Lovely.

I wonder if that stuck in the pitch slightly. She went through the shot early and it was a nice, simple catch for Heather Knight. Spirit will be pleased with that. When Winfield-Hill is in, she can be very destructive.

That was an easy catch for Heather Knight - she did not have to move as the ball looped up towards her.
Winfield-Hill c Knight b Munro 1 (Superchargers 8-1)
BIG wicket!
Sophie Munro had thrown down a couple of wides, but she gets her off-stump line eventually and Lauren Winfield-Hill, who is coming down the pitch slightly, just loops up a simple catch to Heather Knight in the covers.
That is an ideal start for Spirit.
Deepti Sharma goes for just six from the first set - a decent start for Spirit.
Sophie Munro, who is just 19, is on now. This is just her second game in the tournament.
Shot!
Jemimah Rodrigues has been a star of the tournament so far - she's currently the leading scorer in the women's competition and leading the MVP award.
She gets off the mark with a crunching sweep through square leg for four.
Lauren Winfield-Hill gets off the mark with a lovely drive down to long on for a single.
India all-rounder Deepti Sharma is going to get us under way with her right-arm spin.
The players are making their way out to the middle, greeted by the fireworks.
The sun is shining at Lord's too.
Hopefully we're set for an absolute cracker.
The weather has been a bit hit and miss so far at Lord's in this tournament, but thankfully it looks set fair for the women's game, and the men's game at 18:30 BST.
