WICKET
Nabi c Davies b Mills 9 (Spirit 135-6)
London Spirit are making a right hash of this!
Tymal Mills takes pace off the delivery and Mohammad Nabi completely mis-times his stroke to pick out Alex Davies in the covers.
Southern Brave are favourites now - no set batters in for Spirit and Chris Jordan to bowl the final five.
Spirit 135-5
Need 11 runs to win
Chaos as Spirit sneak a bye through to De Kock.
Chance of a run out at both ends but neither come off.
Spirit 134-5
Need 12 runs to win
Take a bow, Liam Dawson.
A fine diving stop on the rope as Mohammad Nabi looked to have flashed it off the edge for four.
Should be two but Dawson gets it in so quickly, it's just a single.
Brave do miss the cut-off and have to bring a fielder up.
Spirit 133-5
Need 13 runs to win
Van der Merwe inside edges it just past his stumps and they sneak a single through to keeper De Kock.
Spirit 132-5
Need 14 runs to win
Swing and a miss by Van der Merwe.
Lightning from Mills.

Spirit 132-5
Need 14 runs to win
Nabi slashes out to the deep to pick up two.
I don't think Brave are going to make the cut-off time here.
Mills will have to bowl five balls in three minutes.
They could well have to bring another fielder into the ring.

Chris Jordan is so chilled under pressure. He's so used to closing out games.

Chris Jordan does this so well.
Spirit 130-5
Chris Jordan gets his radar spot on this time, round the wicket to right-hander Mohammad Nabi and right on the margin with a wide-ish one angled across.
Nabi misses and it's not wide enough to be called wide.

Quinton de Kock was full-stretch Superman there. Wow!
