Muted appeal from Felix Organ as he thinks Dom Sibley has edged into the gloves of Ben Brown, who then whips the bails off.

No catch, no stumping.

Sibley drops the next into the leg side for a single to reach 30* and Matt Fisher negotiates the final four balls without alarm.

The Hampshire over rate is still -2 which may explain why Organ is bowling so early today.

Dom Sibley picks up the first run of the morning from the final ball of Sonny Baker's over with a flick off his hip to fine leg.

He'll keep strike for the second, which will be bowled by Felix Organ from the Pavilion End.

Spin first thing. Interesting.

Dom Sibley resumes on strike on 28* with nightwatch Matt Fisher on 7*.

Sonny Baker will bowl the opening over of the day from the Vauxhall End.

If we get any rain today that will put the kybosh on any hopes of a positive result.

We can't afford to lose any more time in this game...

Surrey’s Jordan Clark claimed 4-64 but could not help prise Hampshire out for below 272 and enforce the follow-on on Tuesday.

He said: “The ideal situation would have been to take all ten and force the follow on and it was looking quite good at one stage.

"But the overhead conditions changed and it was a nice afternoon and the lateral movement wasn’t there.

"We need to set a foundation with the bat and see where we are. It’s going to require a lot of hard work but we definitely believe we still have a chance (of winning).

"I felt good with the ball. Transitioning from the white ball into the red has been quite good. You ramp up the intent for T20 and bring that into red-ball cricket. If you keep moving and you can manage your tiredness you can crack on.”

I strongly suspect Simon is referring to the decision to bowl offy Will Jacks straight after tea on day three, with Hampshire on 238-8, 34 runs shy of the follow-on. 25 of them came off his first two overs.

Burns later dragged on off Kyle Abbott to depart for 10.

After hitting an unbeaten 84 to guide Hampshire past the follow-on target on the third afternoon Delano Potgieter said: "When I came in (at 173-6) it was a tricky situation and they were bowling extremely well at that stage.

"I was hit on the chest second ball which hasn’t happened to me for a long time and it was quite painful and then I got hit on the finger with the new ball.

"But it was nice to contribute with the bat and credit to our lower order, we were able to put together some nice partnerships at the back end. They didn’t give us a lot to hit.

"The wicket has got better to bat on and we’re going in the right direction with our batting. We will take a lot of confidence going into the final day."

If you've been with us for the past three days you'll be well aware it's not been easy going and the ground staff have probably put more miles on the clock than the bowlers.

We lost five overs to bad light on the first evening, only 24 were possible in the whole of day two, and we had mini-sessions of eight and 25 minutes on the third morning due to sharp summer showers.

I'm afraid I'm not confident we'll see 96 overs today either, our colleagues at BBC Weather suggest a sunny morning will give way to cloud with the chance of further showers through the day.

We've seen the bowling conditions have been helped immensely by cloud cover and there's been a lot of late swing off a green track which hasn't dried out an awful lot across the first three days.

Whatever you're expecting to happen, almost certainly won't, and isn't that why we love cricket?

From 173-6 to 333, it was some recovery from Hampshire yesterday afternoon, thanks largely to the defiance of Jake Lehmann (69) and Delano Potgieter (84*).

James Fuller's explosion - hitting 18 runs from four deliveries from off-spinner Will Jacks right after tea - helped avert the threat of the follow-on while last man Kyle Abbott hung around with Potgieter for more than an hour to reduce the deficit to double figures before the reply was over.

Abbott then picked up his 30th wicket of the season to oust Rory Burns early in the reply and Fuller produced a fine caught-and-bowled to account for Jacks, but Surrey have a lead of 145 runs going into the final day with eight wickets in hand and Dom Sibley and nightwatch Matt Fisher at the crease.

You'd imagine the order of the day will be to build a lead north of 300 before having a crack at getting 10 wickets on a spicy track which remains pretty green on the final day.

Hampshire will have other ideas, of course, aiming to set up a possible chase by making early inroads.

Should be a cracking day.

Good morning, welcome to the final day of what has been an absorbing sole County Championship fixture of the week.

Hampshire's defiance with the bat on the third afternoon looks to have staved off the immediate threat of defeat as Division One's bottom side blasted past the follow-on target after tea, with just two wickets remaining, and ended-up tripling their batting points tally for the season in their seventh match.

Surrey lost a couple of wickets before stumps but have a lead of 145 going into day four and will surely look to put the pedal down before having a crack at bowling Hampshire out for a second time late in the day for a win which would take them top of the table,

Let's bring you up to speed before the scheduled start of play at 11:00 BST.
