Manchester Originals: Jos Buttler, Phil Salt, Max Holden, Laurie Evans, Wayne Madsen, Paul Walter, Jamie Overton, Calvin Harrison, Josh Little, Zaman Khan, Richard Gleeson.

Southern Brave: Finn Allen, Devon Conway, James Vince, Leus du Plooy, Colin Ackermann, Mitchell Santner, George Garton, Chris Jordan, Rehan Ahmed, Craig Overton, Tymal Mills.

Craig Overton comes in for Joe Weatherley in the only change to the Brave line-up. Originals bring in three - with Max Holden, Josh Little, and Richard Gleeson replacing Ashton Turner (who has departed for Australia international duty), Tom Hartley and Josh Tongue.

So there's one less spin bowling option for Originals, with Little and Gleeson both bowling seam.

You always bowl first when you're not sure about the conditions and that hampered Originals in the last group game between these two.

So it was quite a predictable decision.

I am looking forward to seeing the battle of the Overton twins.

Southern Brave captain James Vince: "I would have had a bowl first but it looks a decent pitch, like it is normally at The Oval, so hopefully runs on the board in a knockout game helps.

"We've got Craig Overton coming back in and having an extra seamer in could help.

"We know they are a quality side and we came out on top the other night but hopefully similar tonight and get ourselves through to the final."

Manchester Originals captain Jos Buttler on Sky Sports: "We'll bowl first, with the weather around we fancy a chase today.

"Josh Little, Richard Gleeson and Max Holden come in. We're excited for a great game.

"We lost to them the other night but that's behind us now. This is a one-off game to get us into the final."

Manchester Originals have won the toss and captain Jos Buttler has chosen to bowl.

Manchester Originals finished ahead of Southern Brave in the men's table thanks to their superior run rate.

Both sides finished with four wins, three losses and one no result for nine points, four short of table-toppers Oval Invincibles, who progressed straight to the final.

That table positioning means that should this match fall to the weather, it will be Originals that advance to tomorrow's final at Lord's.

Right, we've got your match information.

We'll have the toss at the extremely precise time of 18:02 BST with a full match set to start at 18:30. That means we haven't lost any balls at this stage.

Southern Brave's Chris Jordan is currently sat in the Sky commentary box.

Given he'll be in need of a warm-up, I can't imagine we'll be getting going at the original start time of 18:00 BST.

The Hundred and the weather... it's been complicated.

We were meant to be bathed in August sunshine, but instead a slew of matches have fallen to stormy conditions.

The women's eliminator between Welsh Fire and Northern Superchargers was the ninth game this month to end in a no result, will the men's match between Manchester Originals and Southern Brave become the tenth?

Just an hour after the women were forced off by lightning, The Oval is under blue skies. We await an umpire's inspection at 17:40... which is just about now.
