It's a really good wicket for the Fire. McDermott is such a dangerous batsman. It was a bit of a nothing shot in the end, he just lollipopped it to the fielder.
McDermott c Pretorius b Sodhi 32 (Spirit 90-4)
Ish Sodhi has done it again - Ben McDermott goes!
McDermott goes for the reverse sweep but can only lob the ball straight to Dwaine Pretorius at point!
Jake Ball on the player mic: "Anybody else would've caught that five yards in. I'm quite far away from him [Duckett] but it looks like he's in some sort of hole. Nah, that was a brilliant effort."
"It's good fun, how can you not enjoy this? Packed crowd, bit of sun."

Oh my word, that is outstanding! Ben Duckett, he's managed to throw his arms at it, catch the ball and put it back in.
That is just incredible, I could watch that all night long.
OH MY WORD, BEN DUCKETT!
That is one of the best pieces of fielding I have ever seen! Ben McDermott has hammered a full toss from Dwaine Pretorius that looked six all the way, but Duckett has dived one-handed to catch the ball and, realising he was tumbling over the boundary rope, threw the ball onto the outfield to prevent the six and Spirit can only run two.
Absolutely sensational.
Nathan Ellis speaking to BBC Sport: "I think it's a pretty good wicket. These to will steady the ship a little bit for the big guns to have a go a bit later."
On playing at Lord's: "It's unreal, with the atmosphere like it is here tonight."
When your luck is in. Ben McDermott slashes at a wide one from David Payne and the ball fizzes fine off the edge and wide of the wicketkeeper for four.

Dan Lawrence is a very good player of spin. He uses his feet very well and has good wrists. He hasn't quite gotten going in the tournament yet but this a good opportunity for him.
Time for some more spin as Matt Critchley comes into the attack.
Dan Lawrence does really well to work the ball into some space in the on-side to bring himself two. Ben McDermott then charges Critchley and hits an uppish drive that is fielded by the man of the boundary for another two.
Jake Ball was briefly excited about another catch then but Ben McDermott has simply smacked it over his head for six.
That's the way to do it.
Jake Ball on the player mic: "I made it look a bit better than it should've been. I misjudged it a little bit. A lot of the lads didn't expect me to hold onto that."
"Morgs [Morgan] was a bit unlucky there, it just stuck in my hand. I don't know what I'm doing here though. It'll go on the Instagram later."

It's an absolute stunner from Jake Ball!

That's a big wicket in this situation.
Morgan c Ball b Cobb 0 (Spirit 57-3)
What a stunning catch from Jake Ball! Eoin Morgan goes for a duck!
Morgan has chipped a delivery on to the on side and Ball has dived forward full stretch coming off the boundary at long-off to take a brilliant, brilliant catch.
Isa Guha
Former England bowler on BBC Two
There was a loud cheer around the ground when Eoin Morgan walked in.

Talk about building pressure and that's exactly what Sodhi did.
Rossington c Duckett b Sodhi 32 (Spirit 56-2)
Adam Rossington goes!
Ish Sodhi has bowled very well so far and gets his reward as Rossington loops the ball up to Ben Duckett at mid-on.

McDermott is a fantastic player. He can be very dangerous if he gets going.
