Leics all out for just 123 in 19.2 overs
Glamorgan seamer Meschede takes 3-17
Colin Ingram scores half-century in just 38 balls for hosts
Glamorgan ease home in 13.4 overs
De Lange 3-0-20-2
Marchant de Lange came back on there for Glamorgan from the River Taff End and bagged his second wicket of the evening.
He got the ball rolling earlier with the wicket of Cameron Delport in case you weren't with us and you can watch that wicket back below...
The man with the trumpet in the Swalec Stadium crowd is proving popular as he plays a few tunes to plenty of cheers as well.
Leicestershire 98-8
Well, we've really seen it all now for Leicestershire in this innings and not in a good way.
Mathew Pillans tries to evade a short ball from Marchant de Lange and the ball ricochets off his elbow and rolls back on to his own stumps.
Sorry stuff this now for the Foxes.
Ingram 4-0-19-1
Clint McKay the Leicestershire T20 skipper in now. A penny for his thoughts as he strides out to the middle probably a lot earlier than he intended.
Just one run conceded off Colin Ingram's final over. A dozen dot balls from him as well in his spell.

It's very, very disappointing. If you're a Leicestershire player, coach or fan, it's been a pretty dismal last six or seven overs.
They got off to a flying start and it's all gone downhill from there.

Oh my! That's pretty simple really for Colin Ingram and Glamorgan.
Tom Wells lobs a simple catch right back to the bowler and Leicestershire have lost their seventh wicket.
They may not even see out the full 20 overs at this stage...
Meschede 4-0-17-3
Take a bow Craig Meschede. That could well end up being a match-winning spell of four overs.
Twelve dot balls in among his three wickets and his partnership with Colin Ingram in these middle overs may well prove decisive on the night.

They're really struggling to find momentum.
Glamorgan are well on top here. Leicestershire are in trouble.
Leicestershire 90-6
It's unravelling horribly now this innings for Leicestershire.
Craig Meschede into his final over and he bags a third wicket of the evening. Ned Eckersley slashes a wide ball to Michael Hogan at short third man.
Delight abounds for the men from south Wales.
Eckersley 24, Wells 0
Pressure on Ned Eckersley's shoulders now after that run out as Glamorgan keep being disciplined in the field.
Tom Wells the new man out in the middle for Leicestershire.
Leicestershire 87-5
Oh dear! That's not what you want to be doing when you're trying to score vital runs in a quarter-final.
Aadil Ali is run out going for a dangerous second run with Ned Eckersley.
Ali a long way short of safety as Kiran Carlson's throw is well gathered by Colin Ingram at the bowler's end and the batsman is short by a pace or two.
Eckersley 22, Ali 1
Craig Meschede bowls an absolute peach of a ball to Ned Eckersley that squares him up and somehow beats the outside edge.
But, television slow-mo suggests he may have actually got a scratch on that through to the keeper.
Eckersley not to be put off by that looks busy and forces a couple of runs down to third man and then just survives a half-chance for a catch at extra cover.
Eckersley 19, Ali 0
Colin Ingram continues from the Cathedral Road End and Aadil Ali is the new batsman in for Leicestershire.
Big test now for this Foxes middle order to steer them through the rest of the innings.
Ned Eckersley keeps finding a timely boundary, if not all that convincing off his outside edge, while Ali survives a big leg before shout.

Cosgrove is a key man, a seasoned professional. He's been around for donkey's years in county cricket and played international cricket.
Four early wickets - it's what Glamorgan wanted. Leicestershire need to reset and go again.

Another big wicket for Glamorgan. Mark Cosgrove plays on to Craig Meschede who has two in two overs for the hosts.
It was looking like a chance for Leicestershire to start building a partnership, but Glamorgan snuff it out before it can get going.
Cosgrove 13, Eckersley 9
Colin Ingram on as the sixth different Glamorgan bowler already with his leg breaks.
Ned Eckersley finds a welcome boundary with a slashed four fine of third man. Jacques Rudolph was an interested party at slip for a while.
Eckersley escapes with a mis-timed sweep down to long leg, but no fielder is near it as the setting sun presents the odd problem. Ten off that over for Leicestershire.
Cosgrove 11, Eckersley 1
Tidy first over from Craig Meschede.
Just the two runs from it and a wicket. Time for Mark Cosgrove and Ned Eckersley to do a bit of rebuilding.
Leicestershire 57-3
Another timely wicket there for Glamorgan and Craig Meschede picks up a scalp with just his second ball.
Colin Ackermann pulls the ball right down the throat of the waiting Aneurin Donald on the deep square leg boundary.
Ned Eckersley the new man in.
Leicestershire 57-2
Image source, Getty ImagesSix overs done and plenty to talk about there in the Powerplay.
A couple of wickets for the hosts but some handsome boundaries as well from Leicestershire after electing to bat first.

Cosgrove 10, Ackermann 6
That's not a bad way to get off the mark!
Colin Ackermann slog sweeps new bowler Andrew Salter over the deep square leg boundary for a handsome six.
Lovely shot, always in control of it.

That's a huge wicket. They've got the dangerman. Not only is he Leicestershire's top run-scorer but he goes at a rate of knots as well.
Wagg was on the money, got through the defences and it's a big loss for Leicestershire.
