Joey Evison serves up an over that costs 10 runs, including back-to-back fours for James Vince.

Now the Hampshire captain slog sweeps Matt Parkinson for another boundary. The wheels may well have come off for Kent now.

What does Daniel Bell-Drummond do now?

Middlesex continue to shed wickets at Leicester as the Foxes look to forge a sizeable first innings lead, despite compiling just 179 in their knock.

An easy single for James Vince off Matt Parkinson finally sees him bring up the century that has seemed on the cards from early on.

It is a 30th of his first-class career and second of the season after his 166 not out against Warwickshire last week.

He and Ben Brown have now put on 152 for this fourth wicket.

Essex are looking to the spin of Simon Harmer to get the breakthrough and has Sai Sudharsan playing inside the line with bat behind pad, but the batter survives the over.

The fifth wicket partnership is up to 69.

Jamie Smith gets a single off Jamie Porter, who waves the physio on to the field after appearing to take a stinging blow to the finger fielding a drive struck by Sai Sudharsan.

He's leaving the field with two balls left in the 51st over.

Paul Walter will take over.

Charlie Stobo and Grant Stewart aside, Kent haven’t really made the most of asking Hampshire to bat first.

Nathan Gilchrist is still recovering from an ankle injury and hasn’t really bowled enough balls in the right place.

Joey Evison, too, hasn’t backed up the two main bowlers.

This has left Kent relying chiefly on Matt Parkinson’s leg breaks to keep the run rate in check when they should be looking to take wickets.

There is a green tinge to the wicket but the bowlers haven’t really created enough pressure over a long period of time.

The George Balderson wicket was a timely one for Nottinghamshire.

Another tidy over from Tom Lammonby, costing just two singles.

That's 80 bowled in the innings and Umpire Rob Bailey signals that the new ball has been taken straight away.

Josh Davey will bowl.

A leg slip comes in for Paul Walter but Jamie Smith is blissfully unperturbed with four driven serenely through mid off.

He's very much the key wicket for both sides in this session of play.

Two fours in three balls from Ben Brown off Nathan Gilchrist.

It feels like the wheels are wobbling on the Kent car as the 200 comes up.

This game continues to move along at the speed of light, with 20 wickets falling in less than 68 overs.

Replying to Sussex's meagre 143, Northants failed to make it into three figures, bowled out for 97, as Ollie Robinson took 4-42.

Remarkably, Sussex have a first innings lead of 46.

Josh Davey replaces Jack Leach in the attack and pauses after two balls to inspect the foot marks.

His third ball is driven through point by Chris Woakes for one.

Michael Burgess is well forward on the drive but can't pierce the off side field this time.

Two runs punched through the off side on the back foot.

Keaton Jennings has played wonderfully well.

It's been a real assured innings.

Really well organised play and solid defensively.
