This is a big, big delivery. It has to be a boundary.
Quick single stolen, Luff on strike.
Need 21 more runs to win
It's Linsey Smith to bowl the penultimate five balls. Misfield! Monaghan gets a thick inside edge, it should just be one but the fielder misses it.
They come back for two but that might suit the Superchargers, Luff still off strike.

If she isn't hitting boundaries Alice Monaghan has to get off strike.
Need 23 more runs to win
A single for Alice Monaghan to end the set from Higham.
That suits the Superchargers just fine, it keeps Luff off strike.
Before we enter the last 10 balls, though, we're going to have a strategic timeout.

This is going to the wire. The Superchargers are ahead but a good set of five for London Spirit and it could all change.
Dattani c Wolvaardt b Higham 5 (Spirit 104-5)
Caught in the deep! This game takes another turn!
Naomi Dattani had struggled to get going and tries to change that by swinging the ball away over the ropes.
She doesn't get hold of it though and Laura Wolvaardt takes the catch under pressure at deep mid wicket.

A brilliant huge hit into the stand and dropped in the front row by the man in the blue shirt!
Need 25 more runs to win
Big, big hit and that is brilliant from Sophie Luff!
She's hoisted Higham over deep mid wicket and into the stands. The one is going to the wire!
Need 31 more runs to win
Dot ball, a good one to finish from Langston.
Need 31 more runs to win!
Slapped down the ground for four! Top shot from Sophie Luff, dearly needed runs for the Spirit.
Need 36 more runs to win
Luff is really trying to push it with her running between the wickets. Just singles from the first two balls of Langston's set.
It's up to two runs a ball needed for the Spirit.

In the last 20 deliveries London Spirit have found the boundary once. In the next 20 you think they are going to have to find it at least five times.
Need 38 more runs to win
It's a slow pitch at Headingley and that is making the spinners all the more effective.
Lucy Higham gets through another superb set. It's another five balls that tilts the game in favour of the Superchargers.
Need 42 more runs to win
That's a really good set of 10 from Katie Levick, only eight runs conceded and the wicket of Amelia Kerr.
That could be a game-winning 10 deliveries. It's certainly ramped up the pressure on the Spirit.

Alice Davidson-Richards gave it the Alan Shearer celebration after taking that catch with the one hand in the air pointing to the crowd. She knows what a big moment that could be.
A Kerr c Davidson-Richards b Levick 16 (Spirit 85-4)
Caught in the deep! Big wicket!
Amelia Kerr will not be happy with herself. She's chipped it straight down the throat of Alice Davidson-Richards at long off.
It was almost a checked drive, if she'd followed through with the shot, the ball may well have sailed over ADR's head into the stands.
