Leaders The Blaze are 186-8 in the 42nd over against Lancashire after England Amy Jones made 52 off 76 balls at the top of the order.

Surrey captain Bryony Smith has just reached 100 at better than a run per ball against Somerset and they are 218-2 in the 33rd.

Georgia Adams is 84 not out for Hampshire, who have recovered from 32-2 to reach 225-4 in the 45th against Essex at the Utilita Bowl.

In the remaining game, Warwickshire are looking for runs from their lower order - they are 199-7 after 44 overs at the Riverside against Durham.

Tom Alsop and James Coles added 125 for the fourth wicket to put Sussex in a dominant position in this match but neither managed to stick around for the full session.

Sussex will want to push on hard in the afternoon to stretch the lead up beyond 350.

But with Ollie Robinson, James Hayes, Ari Karvelas and Fynn Hudson-Prentice all in the wickets in a first innings which saw Worcs struggle with the bat, the chance to go and win a second match of their season is there.

It's been an interesting morning.

Sussex are in the driving seat, but I think Worcestershire have bowled pretty well.

They have this big lead, but the game is not completely out of range for Worcester. If they can nip a couple out then there could still be quite a bit in this game.

It took Adam Lyth 196 balls to reach 100, but he only needed 41 more progress to 150, reaching it by steering Matt Critchley for a single.

The Yorkshire lead is 333 and with five sessions left and eight wickets remaining, the White Rose will likely be looking for one north of 400 before asking Essex to begin the chase.

Lyth is 151 not out at lunch, having put on 153 with James Wharton, who top edged a catch off Simon Harmer on 61.

Two centuries from Liam Patterson-White, who walks off at lunch with 120, and a second of the season for Jack Haynes (117) have put Notts in complete control of this contest.

Nice touch from Hants players who applaud the two over the rope at the end of a bruising session which has seen the hosts put on 139 for the seventh wicket.

With the lead over 450 a declaration should be forthcoming but Notts will be mindful of the fact that batting looks easy against the old ball.

So far, so good for Kent as Ben Compton and Harry Finch survive 11 overs before lunch after Glamorgan enforced the follow-on.

The home side added 57 to their overnight 155-8 before being bowled out for 212.

Zain ul-Hassan took the final two wickets, leaving Chris Benjamin unbeaten on 94.

Kent trail by 318 and it is going to take something special from their batters second time around to avoid losing this one.

We can't call that a dropped catch because the ball hit Kai Smith on the foot at short leg, but it was a mighty near thing for Dan Lawrence in the final over before lunch.

Lawrence survives and it has been a satisfactory morning for Surrey at Edgbaston, with 69 runs added for the loss of Ryan Patel.

The story is all about survival for them and Warwickshire's bowlers - like their Surrey counterparts - are struggling to extract anything from the pitch.

Beau Webster took the one wicket to fall, with Patel caught behind after a 78-run stand with Dom Sibley, who remains on 62 not out.

We've seen Zen Malik score a maiden century for Warwickshire in this game. Now he's got a chance to shine with the ball.

His first delivery is short of a length and clipped away for four by Dom Sibley, who adds a single to rotate the strike.

Rob Yates starts another over and Dan Lawrence punches his first delivery to mid-off for a single as the Surrey total reaches 150.

Just as it was over the first two days, this is very hard work for the bowling side.

Yorkshire have been batting very well but it has to be said that some of the bowling has not been at the highest order.

Adam Lyth really has put the pedal to the metal since he got to that 100 mark. Incidentally, there are just two counties now that Adam Lyth is yet to score a first-class century against - Worcestershire and Derbyshire.

Yorkshire are really looking to get on with this now.

Adam Lyth dances backwards to give himself room before cutting Matt Critchley for four and two balls later produces a reverse sweep, which also finds the boundary. He is 139 not out.

Kent's openers have safely negotiated the first three overs of their second innings, having been asked to follow on by Glamorgan.

Timm van der Gugten has sent down two maidens so far and James Harris is now into his second over.

James Coles and Tom Alsop are starting to take this game away from Worcestershire, they’ve passed a 100 partnership and both have posted half centuries

Coles has been particularly impressive with stylish shots around the ground, while Alsop has been more circumspect, but has grown in confidence throughout the morning.

The pitch doesn’t appear to be offering the assistance to the seamers as on the first two days, and Worcestershire may need a similar rearguard action that they displayed at Somerset earlier this season to avoid defeat.
