Nigel Llong is getting a round of applause from the crowd and his fellow umpire! It is a rare round of applause for the umpires today.

What a brilliant bit of work from the umpire!
Whatever we say about cricket it is a high-risk sport for the umpire at the non-striker's end.
That took some agility!
Woah! This could have been really, really nasty. The ball is smashed back at umpire Nigel Llong and would have caused serious damage but for a 007-style roll to get out of the way.
His fellow umpire and the crowd are applauding as that move is shown on the screen.
This Invincibles bowling line-up is good, isn't it? They've got international stars wherever you look. Reece Topley is on now.

These dot balls will be building more and more pressure on the batters.
Need 75 more runs to win
Mahmood comes back well with two deliveries that don't cost a run. It would take something extraordinary for the Rockets to win this now.
Consecutive fours for Samit Patel!

Sunil Narine has given the Invincibles the upperhand.
I would have bowled him a 10 there, but Sam Billings must have decided to keep him back in case Rockets get a partnership.
Saqib Mahmood is slapped to the boundary by Samit Patel and stomps back to his mark more than a little angrily.

Moores should have gone a little bit straighter with that, but that was the pressure of the situation. He knew he had to go.
It will be interesting to see if Sam Billings keeps Sunil Narine on here.

That went very high - way above the pavillion for our perspective!
Moores c Evans b Narine 1 (Rockets 42-4)
The Oval Invincibles are charging towards victory as Sunil Narine picks up his third wicket! Tom Moores has give it a whack but only offers a skier of a catch. Delight for the home crowd.

Trent Rockets need everything to go there way now. They need every ball to miss the fielder and go to the boundary.

You just wonder if that makes it a mountain too big to climb for the Rockets. Hales is such a big wicket.

Gone! Sunil Narine returns and knocks Alex Hales' middle stump clean out of the ground. Is that a match-winning moment?
Henry Moeran

Alex Hales is starting to find a little bit of rhythm, even though he's still hobbling. Maybe the decision is 'it's easier if I just hit boundaries, rather than taking singles'.
Target 126
The Rockets needed this! Hales swings hard, heaving the ball towards the stands.
Reece Topley is on the boundary and is a very tall man but can't get there despite an impressive leap.
Tabraiz Shamsi is on now - the number one T20 bowler in the world. Good luck, Rockets. Good luck.
