Haseeb Hameed is keen to keep Notts ticking. He drives Jaydev Unadkat through the covers for four to go to 18.

Freddie McCann is the new man at the crease for the visitors after Ben Slater's dismissal.

A third maiden of Somerset's run chase with no score off Ben Coad's second over.

Still Somerset await their first run of the second innings.

That was a fine piece of bowling from Scott Currie to dismiss Rishi Patel, full at the stumps and a hint of movement away.

Rehan Ahmed sees out the over.

James Fuller gets a ball to seam back sharply to Sheridon Gumbs in the next over, not missing the stumps by a lot as the opener leaves the ball.

Gumbs gets a leg bye off the third ball and Ahmed is back with one foot off the ground to slap a wide ball through point for four. Stylish.

Maiden over to start for Ben Cliff. Somerset are still 0-1 after two overs.

Here comes Ben Cliff for Yorkshire, fresh off the back of a career-best 8-76 in the first innings.

Tom Lammonby is on a pair for Somerset. He'll be keen to get off that asap.

That's exactly the start Yorkshire (and Warwickshire and Nottinghamshire) would have hoped for.

Couldn't have started worse for Somerset. Wicket maiden first over for Ben Coad with Josh Thomas' game already over.

Nicky Potts had a tough act to follow when coming on as an injury replacement for Ben Aitchison who, at the time, was the division's joint highest wicket taker and had scored a century earlier in the match.

But the sub isn't faring badly. He took three wickets in the Northants innings, albeit some poor shots contributed to those.

Now Potts is impressing with the bat hitting six boundaries so far to reach 28 as Derbyshire try to stretch their lead which is currently 274.

As run chases go, they don't come much more important than this one for Somerset.

Their season and hopes of winning a first ever County Championship title rest on what happens in this second innings for the visitors.

A flashing drive outside off by Sheridon Gumbs and a miss off the bowling of James Fuller.

Fuller gets one ball to jag in sharply, perhaps off the footmarks, but Gumbs survives the over.

Ben Slater drills through extra cover off Ari Karvelas for four and he is onto 14.

Notts have reduced the Sussex lead to 89 runs.

Fun in the sun for Glamorgan’s last wicket pair of Mason Crane (114*) and Mir Hamza (35) as they added 98 to push Surrey’s target up to 612.

Crane thrashed his second 50 off 38 balls and then moved past his previous best of 106, against Surrey earlier this season.

Hamza, who had to face just eight balls as Crane moved from 52 to three figures, then joined in the party with some big hits of his own.

Surrey have four sessions to survive, but a draw will be enough to keep Glamorgan up.

A decent start. But we shan't get too excited.

Rishi Patel blocks the first ball from Scott Currie and then waves in the direction of the dressing room. A call for fresh gloves maybe?

The third ball is driven straight and stopped by a diving mid off.

Patel defends down the ground and Sheridon Gumbs picks the ball up from the non-striker's end. Don't you need to ask the fielders for permission to do that?

The sixth ball of the over is carved over backward point on the back foot by Patel for four.

It's getting heated already...
