Dropped again! It's never easy when the ball is dropping over the shoulder like that but it really should have been taken. It's Sophie Luff again.
Oh dear not again?!
Bess Heath attempts an awkward reverse pull shot that loops into the air and should be taken, but Sophie Luff spills her second catching opportunity!
Huge! The biggest shot of the day so far from Bess Heath as she smashes a Charlie Dean delivery over the boundary for six!
There were two fielders on the boundary too so Heath had to get it just right. Brilliant shot.

Heath is providing some excellent entertainment for the home crowd and is taking the Superchargers towards a good total. Well batted, Bess Heath.
Bess Heath makes the most of her good fortune as she nudges two singles to bring up her 50 from just 29 balls featuring nine four.
A great knock so far - but more is needed to drag the Superchargers up to a competitive total.

It's a tough one but it should be taken, especially at this level. It could be a big miss.
Oh no! It's an almost identical shot from Heath and the ball goes straight to Sophie Luff on the boundary, but she lets the ball escape through her grasp and goes away for four!

It's been the Bess Heath show, she's putting Laura Wolvaardt in the shade.

Megan Schutt is too short and the ball sits up nicely for Heath, who pulls it away for four!
Bess Heath has raced on to 39 from 24 balls as we begin a strategic timeout.
These breaks so often bring wickets when play resumes, will it do so this time?

That's a fabulous shot, another reverse sweep and this time she gets it out of the middle. It's good thinking, playing it with the turn.

Heath is toying with Amelia Kerr now. Three boundaries in a row. You're applauding, Deep!
Three boundaries in a row for Bess Heath!
Two switch-hits disappear through the off side and a sweep shot escapes fine past the wicketkeeper.
To top things off they run three the next delivery to complete and expensive set of five from Amelia Kerr - 16 runs from it.
The Superchargers are warming up!

You look at the Superchargers top four with Healy, Rodrigues and Wolvaardt - three international stars - but it is Bess Heath at number three who is stealing the limelight.
Danielle Gibson, guilty of that error in the field a moment ago, has the chance to make amends with the ball - and she does. Just three three runs from her set of five.
London Spirit have been really disciplined with the ball so far.
Freya Davies took the first wicket of the match, bowling Jemimah Rodrigues with her fourth ball of the day.

Well that shot definitely woke me up! It was in the air but straight and always safe.

A great shot, it's straight and goes fast. It gives the home crowd something to cheer, everybody needs to be woken up on this Sunday morning.
That's more like. Bess Heath plays a lovely straight dive back over Charlie Dean's head for four.
Ooh, and that is a mid-field on the boundary! Heath heaves another Dean delivery in the the leg side for what should be just a single, but is escapes through Danielle Gibson and over the rope for four.
