Surrey beat Middlesex by 73 runs
A superb win for Surrey and they've now won their last seven straight against Middlesex.
It was the Curran show in the first half as Tom made 68 and Sam 50 in a stand of 118 for the third wicket.
199-6 seemed plenty and so it proved as only Max Holden really showed for the home side with 43 from 23 balls.
But Middlesex tumbled away from 93-3 to 122 all out.
They now travel to defending champions Hampshire tomorrow while Surrey play Kent at The Oval tomorrow.
Surrey beat Middlesex by 73 runs
Surrey captain Sam Curran tells Sky Sports:
"The message was to take the form and confidence from the Championship into the T20 and we've put on a good performance.
"We've got the luxury of floating a lot of batsmen and we're in a very lucky position.
"Hopefully we can have a consistent side throughout the tournament and the schedule means we won't lose too many players."

I think Surrey will firstly be very happy with that win, but they'll think there'll be room for improvements in all departments too. As in the Championship, someone has always stepped up to the plate with a big performance.
Middlesex shouldn't beat themselves up - this is a very good side with a lot of franchise experience.
The last time Surrey won the T20 was 2003. With what they've got at their disposal they are a very good squad and if they play to their potential they'll be there or there abouts at the end of the competition.
They will be very happy with the winning start and will be looking to back it up against the Kent Spitfires tomorrow night.

Middlesex captain Steve Eskinazi tells Sky Sports:
"We've got two sides here in very different stages of their development and it was always going to be a tough ask for us.
"It's an extremely high standard this competition and you're going to get hurt if you miss."
Middlesex 126 (Cullen c Overton b Atkinson 4) v Surrey 199-6

But his second is swung to long-on and Gus Atkinson has indeed polished Middlesex off.
And completes a thumping win for Surrey.
Middlesex 122-9 v Surrey 199-6
Gus Atkinson to try and finish this off.
John Simpson takes him down the ground but can't clear long-on who takes a good catch running to his left.
Middlesex 120-8 (14 overs) v Surrey 199-6

Middlesex commentator for BBC Radio London
The game is up for Middlesex. They have got to limit the damage here. Net run rate is important. They were always up against it against this strong side but they have been pummelled here against a Surrey side who are without several very good players, not least Jason Roy who had to pull out during the warm-up.
It's not the start Middlesex would have wanted but they have to shake this off, and quickly.
Middlesex 120-8 (14 overs) v Surrey 199-6
Any excitement in this game has quickly disappeared and now it's just how long Middlesex can keep swinging for.
Middlesex 119-8 (13.4 overs) v Surrey 199-6
A full ball from Will Jacks squeezes until the bat of Nathan Fernandes and the 19-year-old's debut ends as his loses his off stump.

Quality comeback rom Sunil Narine, who finishes with 2-37 from his four.

John Simpson sweeps hard and gets four towards Old Father Time.
But no further damage and the asking rate is heading towards two a ball.

Suddenly two fresh batsmen out there.
John Simpson and Martin Andersson very careful against Sunil Narine and now the required rate climbs.
Middlesex 98-6 (10.3 overs) v Surrey 199-6
Kevin Hand
Middlesex commentator for BBC Radio London
They were ahead of the game and ahead of the rate, but they were behind on wickets. They were playing like they had to try and win it in the next two balls. The problem is you can lose it in two balls and we might be seeing that. They were ahead of the game. It feels like they have thrown the wickets away.
Middlesex 98-6 (10.3 overs) v Surrey 199-6
Max Holden was essential to this chase but now Sunil Narine gets him!
He opens up the 10th with a lofted drive wide of deep cover for four.
But then sweeps and is cleaned up by one that skids on a little.
Huge wicket and maybe the game?
Middlesex 93-5 (10 overs) v Surrey 199-6
Bowled him!
Luke Hollman goes too far across his stumps, sweeps and misses and loses his middle stump!
Looks very ugly and now Middlesex running out of batting.

Middlesex 88-3 (9 overs) v Surrey 199-6
20-year-old Tom Lawes into the attack.
Max Holden gives himself room and drives wide of short-third man for four.

Good comeback from Lawes.
Middlesex 80-3 (8 overs) v Surrey 199-6
Sunil Narine for his second over.
And his first ball is slog swept into the Mound Stand for six by Max Holden! Another wonderful blow from the lefty.
He then goes well outside off to sweep over short-fine leg for four.
Holden looking in great touch here and Middlesex up with the rate.
