Warwickshire 8-0 v Glamorgan (Warwickshire require 360 more runs to win)
It has been a pretty watchful beginning to the innings for Warwickshire's opening pair, Alex Davies and Rob Yates.
There was an intrigue as to how they might go about the chase, requiring around five runs per over, in the early overs - do they guard against the loss of early wickets, or look to apply pressure to the Glamorgan bowling unit?
So far they have proceeded with caution.

Northants 204-7 (target 249 to beat Gloucs)

Yorkshire 486 v Surrey 204 & 155 f/o
Image source, SWPIX.comYorkshire have won by an innings for the first time in a decade and what a superb team performance it has been.
You would do well to see a better all-round team performance than that this County Championship season.
George Hill cleans up by bowling Dan Worrall for 18 - taking his off stump on the drive.
A proper win for the White Rose and what a way to go into the T20 campaign. They have completely outplayed Surrey over three and a bit days.
Yorkshire claim 23 points, Surrey just the two.
The match started with centuries from Jonny Bairstow and Adam Lyth after Surrey captain Rory Burns won the toss and put the hosts into bat. Yorkshire put on 486 in total and then bowled Surrey all out for 204 with Hill starring with four-for as Bairstow enforced Surrey to follow-on.
On a rain-affected day three, Harry Brook was given the ball and he took 3-11 yesterday evening. The home side then skittled through the tail in the first session this morning and that is that.
A big reality check for Surrey who suffer their first defeat of the season.

Hampshire 97-5 & 214 v Notts 229

Somerset 526-8d v Sussex 253 & 47-1 f/o
