The ball was swirling in the air and Higgins was swirling underneath it but he takes a good catch. Middlesex finally break the 118-run partnership. Sam Curran will look to give it a real go to get over 200 in these remaining deliveries.
Bear in mind Middlesex's highest score in T20 cricket at Lord's is 210.

Surrey are looking like they are going to be well up and over 200 here. That is going to formidable given the talent Surrey have with bat and ball.
Look at the timing on Tom Curran. They are looking good, Surrey, this is looking ominous for Middlesex.
Middlesex v Surrey 122-2 (13 overs)

What a fantastic catch that was from Tom Helm, Will Jacks didn't get all of it but he's a tall man and he's come running in, he's got a lot of ground to cover and he has to dive forward. It's a great catch. He's sprinting and he has a long way to come down. A very, very good catch.
Middlesex v Surrey 71-2 (8 overs)

A good diving stop and they take three to end the eighth.

Luke Hollman's leg-spin now.
Slightly wide to Sam Curran and he cuts very hard just past cover.

Then a drag down to Will Jacks is heaved towards the Grandstand and all the way for a flat six.
