94 runs and two wickets in the middle session of play today.

Ben Charlesworth is 46 not out and will face Sajid Khan from the River End.
Notts 201 & 390-7 dec v Leics 93 & 249-9
Brilliant by Michael Finan, who drives Luke Fletcher through the covers for four and follows it with a straight drive to the boundary to carry him to a 37-ball 50.
He'll certainly remember his first-class debut - but probably not for the reason he might have expected.
Notts 201 & 390-7 dec v Leics 93 & 234-9
Image source, Rex FeaturesQuite a knock this by Leicestershire number 11 Michael Finan - brave too as he has been dinged on the helmet.
Three more fours in the same Dane Paterson over take him to 44 not out off 33 balls - and he has put on 60 for the last wicket with Callum Parkinson.
Lancashire 276 & 80-0 v Yorkshire 255
Any satisfaction Yorkshire felt at getting close to Lancashire's first-innings total has been knocked out of them in the final 12 overs before the interval.
Luke Wells has hit four sixes and four fours in his 58 off 33 balls and Keaton Jennings has 22 at the other end - and the lead is now 101.
These two put on 180 in the first innings and the visitors need to break this partnership fast.

The wind is up at Taunton and audibly gusting over the effects mic here.

Lancs 276 & 78-0 v Yorks 255
Keaton Jennings shows he can reverse sweep too and it's four runs for the left-hander off Dom Bess.
Luke Wells is down the track later in the over and belts the ball through mid-off for another boundary.
Kent 164 & 30-4 v Essex 573
Two in two for Sam Cook!
First Ben Compton pushes forward and is taken at second slip by one that went down the hill a smidge.
Then first ball, Jack Leaning is held by the same fielder, squared up in the crease to one that also holds it line just enough.
End of the over so Cook’s hat-trick ball will have to wait.
Somerset 248 v Gloucs 343 & 142-2 - lead by 237

Lancs 276 & 60-0 v Yorks 255
Dom Bess is on in only the ninth over at Old Trafford.
Keaton Jennings nudges a single to bring up a 50 partnership with Luke Wells, who continues his assault on the Yorkshire attack with a reverse sweep to third man for four.
Has he done for the over? No - the last ball is drilled over mid-on for the fourth six of Wells' innings.
Somerset 248 v Gloucs 343 & 133-2 - lead by 228
Gloucestershire have dipped below one run per over since the second wicket fell.

The bowler has settled into a good rhythm here - and that's three maidens for him in a row.
Notts 201 & 390-7 dec v Leics 93 & 202-9
Notts have now tried five short of a length balls at Michael Finan and all five have been despatched to the leg-side boundary - two in the latest Dane Paterson over.
Time for a new tactic, chaps.
Kent 164 & 23-2 v Essex 573
Three balls after the restart and Essex have a second wicket.
Daniel Bell-Drummond gets one that comes down the hill and flicks his inside edge.
Excellent low catch from Adam Rossington diving to his left.
Derbys 306 & 152-5 v Durham 223
Derbyshire slump from 147-2 to 152-5 and Wayne Madsen is the latest to go.

Not to be out-done, Keaton Jennings straight drives to the boundary at the start of the next, bowled by Steven Patterson.
Notts 201 & 390-7 dec v Leics 93 & 190-9

Three times he tests out Michael Finan and three times he is pulled to the boundary.
Full marks to the Leicestershire number 11.
