We do it all again tomorrow with a double-header at Old Trafford as Manchester Originals take on Birmingham Phoenix in both the men's and women's competitions.
It's been a dramatic day of cricket - four exciting games, three of them competitive, one featuring some huge hitting from Northern Superchargers. Enjoy the best of the day's action below.
'That's so tight' - Curran
Match hero Tom Curran speaking to Sky Sports: "That run-out, that's so tight. I guess you could say a fair result in the end. It could have gone either way on that last ball.
"When I came in there was one option. We had to go - we needed about 12 a set. They have two world class death bowlers. I was lucky to get a few out of the middle - what a game.
"It was amazing. A lot of the time when you're playing you can't hear the crowd, it's just white noise, but I could hear it there, it was loud. I think Nasser Hussain said that last year we didn't have many close games, now we've had last ball finishes in almost every game - it's been a great start to The Hundred.
"It's always amazing playing here at The Oval. The wicket was a bit two-paced, in the sense that some were flying through, Gus Atkinson had some in our innings, the same with Rauf and Shaheen. But it is a good wicket here and if you do get bat on ball you get good value for your shots and it's a quick outfield."

Crushing for Welsh Fire who thought they'd done enough. Some superb bowling from Haris Rauf and Shaheen Afridi took them close, while Ben Green took two fantastic catches in the deep after dropping a steepler early on.
Match tied
Not out!
The big screen teased us - they showed the word out first! Tom Abell started celebrating, he thought Tom Curran was gone. David Payne had to correct his captain.
That was a magnificent effort from Tom Curran, who finished on 38* off 18 balls, dragging his team into contention. Some magnificent clean hitting.
Umpire review
Curran hits into square! He's racing for two, it's a huge dive as he comes back to the striker's end. Has he beaten the throw?
This is so close!
WICKET
