Beaumont (42) and Dottin (50 not out) fire Spirit to victory

For the Superchargers, they need to create pressure through dot balls and squeeze the batters and then for the Spirit they need t run well between the wickets. That is something they can learn from how the Superchargers played in the first innings. They need to keep calm and carry on.
The players gather for a two-minute tete-a-tete.
I'd be using this time to have a snack, personally.
55 runs needed
A little more aerial than Deandra Dottin intended as she flicks Liz Russell off her pads, but it's just short of the fielder who is stationed on the boundary rope.
The wicket of Heather Knight has halted the Spirit progress as they chase 127. They are still slightly ahead of where the Superchargers were at the halfway stage...

That's a very good, tidy set of five from Katie Levick.
Deandra Dottin gets away with a punchy little drive off Katie Levick that drops just short of the advancing fielder at mid-off.

That's the halfway stage, with London Spirit in a decent position as they search for their second win of the tournament.
A good bit of running from Deandra Dottin to pick up two... or is it?
The umpire sends it upstairs but Dottin has pulled off a good bat slide to make sure she's home safe. She is so quick.
Alice Davidson-Richards returns and watches her first delivery get crashed off Deandra Dottin's pads and away for four.

Smith has bowled well. We have seen in both competitions that spinners have been key to teams doing well. In this competition to go at a run a ball is outstanding.
Jemimah Rodrigues was in superb touch earlier to set up this total for Northern Superchargers.
74 runs needed
New batter Deandra Dotton, incidentally, was a gold medallist for Barbados as a teenager in javelin, discus and shot put in the 2007 CARIFTA Games.
Basically, she's one of those annoying people that is very good at any sport they turn their hand to.

Knight lbw Smith 16 (Spirit 51-2)
Heather Knight has to go!
That didn't look quite right when you saw it in slo-mo but, with the angle Knight was at, the technology reckons the ball was going on to crash into leg stump.
Hello!
Heather Knight tries to play a reverse sweep, misses, and is given out lbw. She sends it straight upstairs...
76 runs needed
Calm as you like from Heather Knight and Tammy Beaumont so far.

Heather Knight has been working on that shot for the couple of years. She has been accessing that area a lot more.

That is lovely ball-striking from the London Spirit captain.
Shot!
A little shimmy of the feet from Heather Knight and she lofts the ball over the head of the close fielders for four.
