Somerset 72-2 v Northants
Fantastic catch by Emilio Gay, who dives across in front of first slip and takes it in both hands.
You have to say Ben Sanderson deserved that wicket - he now has 1-4 from 10 overs, with eight maidens, including that one.
George Bartlett is the new Somerset batter.
Somerset 72-1 v Northants
Ben Sanderson is still keeping it very tight for Northants, but Lizaad Williams is unable to match him and Tom Abell clips a leg-stump half-volley away for four.
He is nine not out and Tom Lammonby has 30.
Surrey 109-3 v Yorks
You can only imagine what words have formed themselves in the mind of Ben Coad.
Ollie Pope tries to come down the wicket Bazball-style, but makes a hash of an attempt to play to leg and a leading edge just clears the cover fielder and runs away for four.
A couple of twos end the over and Pope is now 40 not out.
Gloucs v Warwks 85-3
Will Rhodes drives Payne down the ground for four to reach double figures.
He's struck on the pad next ball but the ball is clearly going down leg.

Solid start to the session for Warwickshire.
Surrey 101-3 v Yorkshire

Hill thinks there was a thin edge by Ben Foakes at the end of the over but again the umpire turns down Yorkshire appeals.
Essex v Lancs 89-7
George Bell had looked in decent touch on first-class debut, certainly one to watch in the years to come.
However, he gets a thick inside edge back onto his stumps as he looks to drive Sam Cook through the off side.
Surrey 95-3 v Yorkshire
Confident appeal by Ben Coad against Ollie Pope. Looks like it came off pad not bat and umpire Alex Wharf says 'no'. Surrey followers breathe a collective sigh of relief.
Surrey 95-3 v Yorkshire
The first boundary of the afternoon as George Hill strays onto the pads and that is easy pickings for Ben Foakes.
The next over starts with a four as Ollie Pope edges Ben Coad and the ball deflects away off third slip's hands and away to the rope. Definitely not a chance.
Worcs 103-5 v Notts
A maiden from Mullaney.
Gareth Roderick is struck on the pads by Paterson and the umpire turns down an LBW shout. A bit high but that must have been close.
In the next over, D'Oliveira guides the Pears past 100 with a steer to square leg off the bowling of Mullaney.
Somerset 55-1 v Northants
As you were at Taunton.
Ben Sanderson bowls the first over of the afternoon to Tom Abell and it is a maiden - his sixth from eight so far.
Hampshire v Kent 39-5
A lovely straight drive back past Mohammad Abbas from Joey Evison to start the afternoon session.
Kent could do with a few more of those.

Dom Sibley resumes on 35 not out with his captain Will Rhodes on four.
Zafar Gohar to bowl from the Pavilion End.

An inside edge brings Ben Foakes his first run and Ollie Pope tucks the next away for two to advance to 23 not out.
Worcs 99-5 v Notts
Great session of play for Division Two leaders Notts this morning, who will be further boosted by the struggles of their nearest rivals Middlesex at Grace Road so far today.

Notts captain Steven Mullaney to bowl the first ball of the session.
