Five more to come in the innings.
Leics v Northants 151-2 (16 overs)
A fifth of the Northants innings left and they're very well placed.
Chris Lynn, who was put down, adds a second six and goes to a 28-ball fifty, also with five fours.

Big moment.
Somerset skipper Tom Abell runs out the Glosters key bat Grant Roelofsen and they're now looking light for the final quarter of their innings.
Lancashire v Derbyshire (19:50 BST)
After some hokey-cokey with the covers from the Lancashire groundstaff, they have finally been removed.
The umpires have clarified that, if there is no more rain, play will begin at 19:50 BST.
It will be 15 overs per side.
Bears 146-3 v Worcs
It's a surprising fact but Glenn Maxwell has still to reach 50 in this season's Blast and he's fallen short again this evening.
One hand comes off the bat as he tries to clear the rope at extra cover and Pat Brown runs round to his left to take a well judged catch.
Just 20 balls faced by the Aussie, who hit three sixes and five fours. The Bears would have wanted him to go deeper towards the end of their innings.

Kent 170-1 (15 overs) v Middlesex
There it is, a second T20 hundred for Daniel Bell-Drummond.
He has been in electric form in the last few games, but he's got to three figures tonight.
Exactly 50 balls, with 10 fours and four maximums and he is setting Kent up for a huge score.
Hants v Essex 72-0 (6 overs)
Image source, Getty ImagesWhat a powerplay here for Essex having been sent in.
Feroze Khushi is 36 from 19 balls and Dan Lawrence 33 from 18.
Victory should seal Essex's place in the quarter-finals.
Bears 143-2 v Worcs
Dan Mousley doesn't need to get his eye in - he's down the track to his second ball faced and lofts Dillion Pennington handsomely over mid-on for six. Seven more overs in the Bears innings.
Somerset v Glos 122-5 (13 overs)
Image source, Getty ImagesThe Glosters are just about back in the game here.

His first of the tournament.
The run-rate is back up at 9.5 but Graeme van Buuren has fallen for 36 from 21 balls.
Kent 151-1 (14 overs) v Middlesex
Joe Denly cracks Luke Hollmann away for his first boundary and to bring up his team's 150.
With six overs left and so many wickets spare, Kent will fancy a score of around 230.
Bears 134-2 v Worcs
Dave Bradley
Cricket commentator on BBC Radio 5 Live Sports Extra
Pennington has probably been the pick of the bowlers to be fair.
His first two overs cost just 16 - that sounds expensive but in the context of this game. it's pretty good going.
Glamorgan v Sussex 102-5 (13.2 overs)
Forget that, Michael Burgess is out!
Burgess tries to flick it into the onside, but misses and Andy Gorvin is on the money and into the stumps.
Bears 134-2 v Worcs
Rob Yates tries to swing Dillon Pennington over mid-wicket but gets a top edge and the Rapids seamer runs across to take the return catch.
Yates made his 59 from 39 balls and shared stands of 80 and 54 with Alex Davies and Glenn Maxwell.
Glamorgan v Sussex 102-4 (13.1 overs)
Michael Burgess with a lovely flick down to the fine leg fence for four to bring up the Sussex 100.
He and Shadab Khan have put on 58 and need to keep going.
Durham 49-1 v Yorkshire

This rain is now rather heavy and looks like it could be here to stay for some time. The weather apps have been changing their minds about this all day.
Bears 134-1 (12 overs) v Worcs
Ged Scott
BBC Sport at Edgbaston
It‘s been quite a week for Australian batters at Edgbaston.
Obviously he is not quite in Pat Cummins‘ class as a Test finisher but this Glenn Maxwell looks quite useful - and sure has a few shots of his own in his locker.
After a rather quiet start to the evening, even from a packed Hollies Stand, it now sounds like the Edgbaston crowd are really startting to enjoy this.
Not many Pears appear to have made the journey though, by the sound of it.
Durham v Yorkshire 49-1
No re-start yet at the Riverside.
Wayne Parnell is missing from the Durham side after picking up an injury in the warm-up.
Hopefully we will see more play but the rain is setting in for now.
Hants v Essex 48-0 (4 overs)
This walloping Essex start continues - despite the second over of the match only going for one run!
Nathan Ellis' first set is taken for 17.
And two more boundaries follow in the next over from John Turner.
Feroze Khushi is 20 from 13 and Surrey-bound Dan Lawrence 26 from 12.
Bears 121-1 v Worcs
Another expensive over from Josh Tongue costs him 15 - he has 0-38 from three so far.
Glenn Maxwell pulls for six over deep backward square and adds two fours as he moves to 30 off 12 balls.
A very dangerous man if like another Glenn - Miller - he's in the mood.
