Marcus Harris has played some lovely on drives in this innings.
He has phlegmatically, philosophically has just got on with it.
The first 100 for a Leicestershire player this season.
Well played.
Essex 123-1 v Lancashire 146
Glenn is right, it is time for Nathan Lyon.
After 16 wicketless overs of seam bowling, Lancashire captain Keaton Jennings turns to the Australia great.
He grabbed five wickets at Hampshire last week. Lancs need him to pull a few rabbits out here.
Gloucestershire have lost their ninth wicket at Hove, with Zafar Gohar bowled by James Coles for 60. Only one more run needed, though, for fourth batting point on 399-9.
Glamorgan have their first point at Wantage Road thanks to a half-century by Mason Crane, brought up with a slog over mid-on for four off Ben Sanderson, and they are now 260-9.

It is cold at Chelmsford, not baltic, but cold which won’t help the Lancashire mood and nor will dropping the nightwatchman Sam Cook in the first over of the morning.
Since then Cook has looked more and more confident while Dean Elgar is beginning to look like the immoveable object he was on his way to a century against Kent last week.
Essex are right on top here and Lancashire may have to turn to Nathan Lyon…
Middx 136-7 v Yorks 159
The Middlesex collapse continues at Lord's - that's five wickets gone this morning for 39 runs, three of them for Ben Coad.
Bowling round the wicket, he beats Jack Davies' defensive stroke and the umpire sends the wicketkeeper on his way.
Hampshire v Warwickshire 391-5
Warwickshire begin the 110th over needing 10 runs to reach a fourth batting point.
Jacob Bethell takes one single from the fifth ball of Liam Dawson's over as the Bears focus on batting big.
The bonus points for this innings end with three for the Bears and only one for Hampshire.
Derbys v Leics 217-3
Image source, Getty ImagesA thoroughbred stroke by Marcus Harris takes him to the first century of his second spell with Leicestershire.
Anuj Dal overpitches and the Australian left-hander drives it back down the ground to the on-side of the stumps for four to reach three figures off 189 balls.
It's his 28th century in first-class cricket.
Essex 113-1 v Lancashire 146
Dean Elgar pushes one out into the offside and sets off for a run, which he makes.
That clocks up the 50 partnership between him and night-watchman Sam Cook.
Only an hour played this morning, but it already feels like this is going to be a LONG day for Lancashire.
Middx 135-6 v Yorks 159
Having just talked him up, Leus du Plooy departs at Lord's as Ben Coad brings one back down the slope and cleans him up.
Barring a major wag of the Middlesex tail, Yorkshire have bowled themselves right back into the game this morning.
Coad now has 2-39 from 12 overs.

James Gulleford: Can anyone explain why games where overs have been lost due to rain always add overs on at the end of the day when there is often bad light rather than starting early like they could have done today? Get the players on the field at 10:30! #bbccricket
That is a good question. It's one of those things about cricket that always vexes us.
Somerset 158-2 v Notts 193
After a slow start in which they lost Sean Dickson, Somerset have started to find their groove.
Josh Davey in particular is looking good, he's just hit three fours in Dane Paterson's last over.
In the next over, Tom Lammonby helps himself to a couple of boundaries off Luke Fletcher - the second a lovely shot straight down the ground.
The hosts only trail by 35 runs now.
Middx 135-5 v Yorks 159
Image source, Rex FeaturesHe's 29 now, but given the age of some of their more recent Test debutants, surely South Africa must be taking a look at Leus du Plooy.
The left-hander went into this game with a first-class average of over 48 following last week's 196 not out against Northants, and two runs to square leg off Ben Coad takes him to another 50 from just 43 balls.
Kent 144-4 v Surrey
The groundstaff are pulling the covers off at the Spitfire Ground and it looks like Kent will be resuming their first innings in the not too distant following that irritating rain shower.
Nightwatcher George Garrett is 20 not out and Joe Denly has 14.
Hampshire v Warwickshire 384-5
Liam Dawson has a reward for his perseverance.
Danny Briggs shuffles across the crease in an attempt to sweep to the short boundary and he is almost yorked as Dawson knocks over the leg stump.
Now can Hampshire follow it up with a couple more wickets?
Derbys v Leics 203-3
Two Australians batting together now for Leicestershire and Peter Handscomb drives the ball back past a sprawling Blair Tickner for four to push the total beyond 200.
Opener Marcus Harris is still there, in no more of a hurry than he was yesterday, and is now on 91 not out
Worcs 115-6 v Durham 244
Problems for the Pears.
Matthew Waite only lasts six balls before being caught behind off Ben Raine, who is very much the Durham danger man at present.
The hosts still trail by 129 and only have four wickets left.
That promising start seems a while ago already.
Hampshire v Warwickshire 379-4
Dan Mousley goes for a quick single and Nick Gubbins goes for the run out.
Mousley is in, the ball misses the stumps and runs off for four overthrows.
It's a lesser spotted five to add to the Warwickshire total.
Worcs 111-5 v Durham 244
The Worcestershire opener takes a single off Matthew Potts and acknowledges the applause for reaching a half-century from 101 balls.
He's really anchored the innings when his side has needed him to.
Northants v Glamorgan 236-9
Image source, Getty ImagesHe may never play a game of international cricket but there are few more reliable seamers around than Ben Sanderson.
Glamorgan loan signing Brad Wheal edges to the keeper and that is the 19th time Sanderson has taken five or more wickets in a first-class innings.
No wonder head coach John Sadler said of him last evening: "Ben Sanderson was magnificent, relentless, keeps asking questions every ball."
