Alarming from a batter's perspective that is.
Hill then steps down and drives Matt Critchley over the mid-on fielder for four to bring up Leicestershire's 200 in the 72nd over.

Lots of chat about how slowly somerset are scoring. Current run rate is around 3, which is the same as both first innings.
Dave, Wiltshire
Indeed, Dave. Somerset have found the knack of just putting their foot on the gas in spurts to keep the scoreboard ticking along despite some spells of very tight bowling by Notts.
Their lead is already 338 with five wickets still in hand.
Lancs 167-4 - target 424
Nice shot by Liam Livingstone to get off the mark, driving straight down the ground for four off Hasan Mahmud.
Lancashire need to rebuild once more.
Notts 193 v Somerset 310 & 220-5
Real frustration for Notts and Dillon Pennington.
Thomas Rew slashes hard outside off stump from Pennington and edges behind.
It's a tough chance for Joe Clarke, diving at full stretch to his right but it goes into the glove before bouncing out.
Rew comes through for a single to go to 58. Will Notts live to rue that missed chance? Or Rew you could say...
Sussex 521 v Glamorgan 155 & 186-2
At this moment, Kiran Carlson and Ben Kellaway are both averaging over 50 in this season's County Championship, so they are a good pair for Glamorgan to have together in this tough situation.
Tom Price drops short and Kellaway cracks the ball away square for four as he progresses to 45 not out.
Leics 187 & 196-5 (f/o) Essex 401

The deficit is down to 18.
Lancs 162-4 - target 424
All of a sudden, this game has very much gone back in Kent's favour.
Two wickets in quick succession and what was looking like an awkward day feels slightly less pressurised for the visitors.
They need six more wickets for the win.
Liam Livingstone is in for Lancashire who still need 262 runs.
Hammond c Bartlett b Guthrie 15 (Northants 465 v Gloucs 268 & 107-3 (f/o)
Big wicket for Northamptonshire!
Miles Hammond drives beautifully through the covers for four, but Liam Guthrie's revenge is swift,
The next ball squares up Hammond and catches the outside edge to give George Bartlett a simple catch at third slip.
James Bracey joins Cameron Bancroft. Plenty needed from this pair.
McDermott run out (Northeast) 0 (Lancs 162-4 - target 424)
What a waste.
Marcus Harris taps it into the covers off Bertie Foreman and decides to take a quick single that doesn't really look on with Ben McDermott always struggling to make up the ground.
Sam Northeast is onto it quickly and launches the throw to the gloves of Chris Benjamin to whip off the bails without breaking stride.
McDermott is just short and has to go for a duck having faced just one ball.
Lancs 162-3 - target 424
That partnership for Lancashire between Keaton Jennings and Marcus Harris was worth 104 runs.
They've got the home side within 262 runs of victory, but now with only seven wickets remaining.
Sussex 521 v Glamorgan 155 & 171-2
As Sussex head coach Paul Farbrace tells BBC listeners that some players will not be offered new contracts because of the club's financial situation, Ben Kellaway edges Tom Price for four as he and Kiran Carlson bring up a half-century stand for Glamorgan.
"I'm having regular conversations with all of the players," adds Farbrace.
Jennings c Benjamin b Mahmud 61 (Lancs 162-3 - target 424)
That's a big wicket for Kent and the celebrations in the field show you they think so too.
Keaton Jennings has been on the attack and walks down the pitch toward Hasan Mahmud.
He tries to flick it round the corner but it brushes his glove and loops down the legside, where wicketkeeper Chris Benjamin is diving across to his right to take a nice catch.
Mahmud now has three-for in this innings and six wickets in the match so far on debut.
Northants 465 v Gloucs 268 & 103-2 (f/o)
Raphy Weatherall in and Miles Hammond pushes down the ground for his second boundary to bring up three figures for the visitors.
They're going to need plenty more where that came from on a pitch which doesn't appear, for now at least, to be misbehaving.
They need 95 more to avoid an innings defeat.
Guest b Potts 0 (Durham 377 v Derbyshire 118 & 217-7)
Image source, ShutterstockTwo in three balls for Matthew Potts as Brooke Guest is totally non-plussed by one which keeps low and removes his off stump.
Derbyshire are still 42 behind - Division Two leaders Durham need three wickets for an innings win.
Andersson c McKinney b Potts 10 (Durham 377 v Derbys 118 & 217-6)
He's had to be patient but Matthew Potts has his 12th five-for in first-class cricket as Martin Andersson advances down the pitch and drives to Ben McKinney at cover.
Potts' first four wickets came in yesterday's final session, but Derbyshire have showed much sterner resistance today.
Lancs 161-2 - target 424
Marcus Harris pushes to the sweeper on the cover boundary off Bertie Foreman to pick up a single and reach 50 from 78 balls.
