Worcestershire Rapids 137-5 beat Gloucestershire 136-8 by five wickets
Thanks to all of you who've joined me today.
It was a game which promised much and largely lived up to expectations, despite the low-scoring nature.
I'll be back in just under 24 hours for the last of the quarter-finals. Until then, goodbye.
Somerset v Nottinghamshire Outlaws (Sunday, 15:00 BST)
We know three of our four Finals Day participants, but you'll have to wait until tomorrow to find out the fourth.
Somerset host Nottinghamshire at Taunton, with the first ball set to be bowled at 15:00 BST.
You can join me again for live text coverage of that one from around 14:45.
Worcestershire Rapids 137-5 beat Gloucestershire 136-8
It's the first time Worcestershire have reached Finals Day, and it's no less than they deserve after putting in a string of sterling outings in the group stages.
Callum Ferguson's 64 from 47 - on a day when nobody else could get to grips with a slow surface - was a phenomenal innings considering the pressure on his shoulders.
Worcestershire Rapids 137-5 v Gloucestershire 136-8
Worcestershire are off to Finals Day!
Callum Ferguson finishes unbeaten on 64, but Ed Barnard has the honour of scoring the winning run, guiding a single down to third man off a Matt Taylor no-ball.
Gloucestershire had their moments, but Brett D'Oliveira's brilliant 4-26 and Ferguson's composed knock proved too much for the visitors in the end.
Worcestershire Rapids 128-5 v Gloucestershire 136-8
A good spell from Jacob Lintott, but without a wicket to show for his efforts.
Just five runs conceded in his fourth over - that's all Worcestershire need now though.
Worcestershire Rapids 123-5 v Gloucestershire 136-8
Andrew Tye's fourth and final over is another good one, but it could have been a great one.
He allows only two runs from five deliveries, but then follows up with two wides and a single to finish.
Just 14 needed for Worcestershire from the final three overs.
Worcestershire Rapids 118-5 v Gloucestershire 136-8
That may just be a match-winning bit of hitting from Ross Whiteley.
Seven runs come off the first three balls, with a no-ball and a wide thrown in there.
Whiteley then launches successive sixes - the first just beating the rope down the ground and the second a big old heave into the leg side.
He's out to the final ball of the over, caught deep on the off-side, but the damage has been done - 22 runs coming from the over.
Worcestershire Rapids 99-4 v Gloucestershire 136-8
...but brilliantly stopped as Ross Whiteley tries to smash the ball to the off-side boundary.
Gloucestershire might say justice was done there - David Payne's full toss was either just above the waist or just below it, depending on your allegiance.
Worcestershire Rapids 98-4 v Gloucestershire 136-8
Free hit coming up...
Worcestershire Rapids 96-4 v Gloucestershire 136-8
This is impossible to call.
Worcestershire need 40 from five overs - on any other surface you'd back them to cruise to their target, but not here.
Andrew Tye allowed just four runs to come off his latest over.
Worcestershire Rapids 92-4 v Gloucestershire 136-8
A better end to the over from Ryan Higgins, but Gloucestershire desperately need another wicket now.
This was their latest one, the dangerous Ben Cox gifting Andrew Tye a catch.
Worcestershire Rapids 92-4 v Gloucestershire 136-8
More medium pace bowling from Gloucestershire, with Ryan Higgins handed the ball for the first time.
He hasn't found his range so far though, a short ball pulled through the leg side for four, before Callum Ferguson brings up his half-century with two runs to the off-side boundary.

Benny Howell's impressive spell comes to an end, seven runs taken from his final over as he records figures of 2-22.
Worcestershire have made hard work of this chase, but they're only 53 short of their target.
Worcestershire Rapids 75-4 v Gloucestershire 136-8
Despite the struggles of his team-mates, Callum Ferguson is still going very nicely for Worcestershire.
He takes two runs off the each of the final three balls of a slightly scruffy Jacob Lintott over, 10 runs coming off it in total.
Ferguson has 40 from 28 deliveries.
Worcestershire Rapids 67-4 v Gloucestershire 136-8
Worcestershire try to counter attack, taking 10 runs from the first four balls of Benny Howell's over.
The Pears' joy is short-lived, however, as Ben Cox gets his timing wrong and chips the ball up to mid-on, where Andrew Tye makes a diving grab.
Worcestershire 55-3 v Gloucestershire 136-8
Halfway through the Worcestershire innings.
The hosts are keeping wickets in hand - perhaps the plan is just to stay in contention until the seamers come back into the attack?
Jacob Lintott matches his efforts from his first over, just five runs given up.
Worcestershire Rapids 50-3 v Gloucestershire 136-8
Just two runs off the over as Gloucestershire crank up the pressure.
Worcestershire need a big over sooner rather than later.
Worcestershire Rapids 48-3 v Gloucestershire 136-8
This is top-drawer bowling from Gloucestershire.
Benny Howell went for just one run and a wicket, and Jacob Lintott follows up by conceding just five runs from his first over.
Worcestershire Rapids 42-3 v Gloucestershire
The change of pace takes just two balls to pay dividends.
Benny Howell's medium pace does for Brett D'Oliveira, the ball holding up in the surface just enough for the Worcestershire all-rounder to it in the air to Andrew Tye.
Worcestershire Rapids 42-2 v Gloucestershire 136-8
End of the powerplay, but no nearer to finding out who will reach finals day.
Worcestershire have the run rate where it needs to be, but the dismissals of Moeen Ali and Joe Clarke have given Gloucestershire a bit of hope.
Benny Howell is coming on for the seventh over.
