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
Cosgrove 9, Ackermann 0
No wonder Luke Ronchi raced his way to 28 off just 18 balls there. Take a look at his strike rate in this year's competition before tonight...
Image source, Getty ImagesIt was a nice little cameo here as well tonight with three fours and a six in that knock.
Colin Ackermann is the new man in at four for Leicestershire.
Leicestershire 49-2
Danger and dismissed for Glamorgan and Graham Wagg is the man who's come on to claim the big wicket of Luke Ronchi.
The New Zeland international swipes across the line and is bowled by a smart slower ball from the left-armer.
Ronchi 27, Cosgrove 4
First six of the night and it's come from the bat of Luke Ronchi with a massive straight maximum off Michael Hogan.
Leicestershire motoring here in the Powerplay. Mark Cosgrove is also off and running with a sweetly-timed pull for four.

Delport was beat for pace, beat for length - it was a perfect yorker right on the popping crease.
It's obviously a ploy they've gone for because he's bowled at least three and Michael Hogan was targeting them earlier.
Ronchi 16, Cosgrove 0
Earlier in that over it was boundary time again for Luke Ronchi with another four off Marchant de Lange. Slashed stroke down to third man as he gives himself room outside leg.
Mark Cosgrove is the new man in for the Foxes and he nearly chips one into the waiting hands of extra cover.
The ball just drops short and the big Australian survives.
Leicestershire 28-1
Beaut of a ball from Marchant de Lange to bag the first wicket of the night.
Cameron Delport is cleaned up for pace and swing with a marvellous yorker that shatters his stumps.
Glamorgan off and running with the ball.
Delport 10, Ronchi 9
Aussie seamer Michael Hogan shares the new white ball for the hosts from the Cathedral Road End.
Luke Ronchi steals a quick single in the infield and Colin Ingram throws and misses at the stumps. Probably out with a direct hit.
Cameron Delport gets hit first boundary with a lofted shot down the ground that just trickles over the rope before following it up with a neat steer down to third man for four more.
James Taylor
Ex-England batsman on BBC Radio 5 live sports extra
Luke Ronchi doesn't need time to get himself in, get his eye in or get the pace of the surface.
He gets that strong base of his and uses exceptional hands and timing to go through the ball.
Ronchi 7, Delport 1
Luke Ronchi gets off and running with a nice flick off his legs for a couple and then a four from a free hit to the deep mid-wicket rope after Cameron Delport banged one in too short.
A round 10 off the first set of six deliveries for the Foxes.

Hampshire beat Derbyshire by 101 runs
In case you were on another planet last night, you may not have realised that Hampshire's Shahid Afridi hit the fastest T20 Blast hundred of 2017 in his side's quarter-final victory against Derbyshire on Tuesday.
The former Pakistan captain reached his century off 42 balls during his side's crushing 101-run win to book them a place at Finals Day.
Watch the all his big hits on a memorable night at the County Ground above.
Glamorgan v Leicestershire Foxes (18:30 BST)
Image source, Getty ImagesLeicestershire T20 captain Clint McKay hopes his side's four-game winning run can give them the momentum to secure a place at T20 Blast Finals Day.
The Foxes are looking to return to Finals Day for the first time since winning the trophy in 2011.
"To win four in a row gives us confidence at Cardiff," McKay told BBC Radio Leicester.
"We always believed we have a very good team and if we turn up and play our best we can beat anyone, as we showed throughout the group stage."
Leicestershire set the early pace in the North Group with four straight victories, but they lost the next five to leave them needing four wins to qualify.
"Going into the last four we knew it was do-or-die, so the boys went out and played with freedom.
"We know we've got a quality squad and some exciting young guys coming through, so it's great for them to know we can beat anybody on our day."
Glamorgan v Leicestershire Foxes (18:30 BST)
Image source, ReutersDavid Miller's a man who's clocked up a fair few air miles this week just to feature in this evening's quarter-final for Glamorgan.
The batsman has flown overnight to be in south Wales after playing for South Africa A yesterday in Potchefstroom against India A.
Miller made just 13 and 18 in the second unofficial Test earlier this week, so he'll hope the red-eye flight back from Johannesburg was all worth it.

Image source, Getty ImagesNews from the middle at the toss of the coin is that Leicestershire Foxes have called correctly and will bat first.
Team news-wise, it's a real cosmopolitan affair tonight in Cardiff with a real smattering of nationalities on show.
No England internationals on either side, but still plenty of international and big match experience.
Glamorgan: Rudolph (c), Donald, Ingram, Miller, Cooke (wk), Carlson, Salter, Meschede, Wagg, de Lange, Hogan.
Leicestershire: Ronchi (wk), Delport, Cosgrove, Ackermann, Eckersley, Aadil, Wells, Pillans, McKay (c), Parkinson, Griffiths.
Daggers has actually just admitted on air that that stat should read nine South Africans and three Australians on show....
Glamorgan v Leicestershire Foxes (18:30 BST)
