Surrey's Dan Lawrence is back out to bat after lunch having gone into the break in some discomfort with a back injury.

He manages to get one away for a single on the leg side from Jordan Buckingham but he still doesn't look overly at ease with the pain.

Kyle Abbott bowls the final four balls of his 13th over to start the afternoon session at Edgbaston.

New batter Zen Malik plays out four dots. The 27-year-old made a century last weekend in just his second first-class match.

How the Bears could do with a repeat today.

Brad Wheal's opening over of the session costs two singles before Ed Barnard goes aerial to a rising ball outside off-stump and picks up a boundary. He moves to nine.

The players are back out around the grounds and we're about to get going for the afternoon session on day two.

Glamorgan enjoyed a one-sided first session as they added a further 134 runs for the loss of Kiran Carlson’s wicket as Northants’ seamers failed to find the threat that the bowlers demonstrated on the first day.

Carlson got Glamorgan’s momentum going in the Cardiff sunshine before he was snared into flicking a leg-side catch to Saif Zaib off Ben Sanderson for 54.

But Northants could not keep the pressure on despite two very tight spells from captain Luke Procter, leading by example as he also threw himself into a couple of boundary saves.

While Sam Northeast reached a patient 50 off 120 balls, the in-form Ben Kellaway was quickly into his stride to take Glamorgan ahead with the promise of a significant lead.

I had to check this out as it seemed far fetched but it was indeed the case! BBC Sport's Chris Charles covered the incredible story back in July 2001.

Wisden called the game "extraordinary" adding "the chances of it happening must be billions to one".

If you're interested, Amarmilan beat Yorkshire LPS by 31 runs.

After six wickets fell yesterday, we had six in the morning session with this game evenly poised.

Somerset lost their last four wickets for just 21 with Nathan McAndrew and Ollie Robinson cleaning up the Somerset tail.

Sussex then lost Haines and Clark before lunch with Matt Henry on his first appearance of the season taking one of the wickets.

There is still help for seamers on this pitch but with sunny conditions could turn this into an excellent batting surface later in the game.

Kurtis Patterson has batted wonderfully on his County Championship debut for his unbeaten 50 and Dan Lawrence (19*) has got himself in as well.

The lead has been cut to just 113 for Yorkshire and Surrey still have eight wickets in hand to work with and close in on that gap.

Surrey 145-2 v Yorkshire 255

Kurtis Patterson rushes through for a quick single and gets a well-deserved 50 on debut for Surrey.

His batting partner Dan Lawrence looks in a bit of discomfort with his back and might need some treatment at lunch.

A perfect morning for the home side as Durham reach lunch unscathed after resuming on 2-0.

James Minto has been superb, bringing up his maiden first-class fifty and goes to lunch unbeaten on 63 from 111 balls.

Alex Lees at the other end is 11 runs shy of his fifty.

The Notts bowlers have been unable to create much danger of what looks a belting batting pitch.

It's all fairly evenly poised as we head for lunch at Taunton.

Somerset suffered a mini-collapse first thing this morning, adding just 21 runs to their overnight score and losing their final four wickets within 40 minutes.

Sussex's in-form batter Tom Haines was caught behind for 24 off Craig Overtonn and Matt Henry trapped Tom Clark LBW for just four as the visitors go for a bite to eat at 68-2.

Glamorgan v Northants 185

Sam Northeast leading the front as usual for Glamorgan as he reaches a half-century in 120 balls.

Northeast is capable of some big scores - might he get another here?

Ben Kellaway at the other end is on 43 and Glamorgan's lead is 31 as we approach lunch.

A perfect end to a brilliant session for Hampshire.

Beau Webster has looked the batter most likely for the Bears, but aims a drive at a Kyle Abbott ball which nips back sharply and thuds into leg stump.

Hampshire have fully pressed home their advantage this morning, picking up four further wickets as the Bears added 76 runs to their overnight 27-2.

It could have been worse - Hampshire shelled three more chances.

Much work for the Bears lower order to drag the hosts back into the match.

Durham 101-0 v Notts 407

James Minto milks a single off Freddie McCann as Durham reach three figures without loss before lunch in the 30th over.

The century opening stand has come off 177 balls.

James Minto has been a revelation in his first knock of the season, dominating the partnership with 62, while Alex Lees has 38.

Full half-volley from Jordan Thompson and Surrey's Kurtis Patterson punishes it with a lovely cover drive.

It races away for four and Patterson is racing towards 50. Just two more needed for a half-century on debut.
