They need a big over from somewhere.

Time for a bit more spin, this time from Dan Lawrence.
Still Derbyshire can't get any momentum going. Three from the over.
They need a big over from somewhere.
Hughes 22, Smit 1
Another fruitful over comes to an end for Essex.
Derbyshire need 79 more from 54 balls. They're in a quandary.
Derbyshire 81-6 (target 161)
Derbyshire are collapsing.
Matt Critchley tries to heave Aaron Nijjar over square leg, misses, and is bowled. The fifth batsman to have his stumps splattered in this innings.
That could well be game over.
Hughes 20, Critchley 4
Alex Hughes breaks the shackles by cutting Simon Harmer to the third-man rope.
But the rest of the over is bang on the money from the Essex spinner.
Halfway point - Essex are well on top you feel.
Hughes 14, Critchley 3
Alex Hughes and Matt Critchley need to stick around for a few overs to give Derbyshire a chance.
Ravi Bopara goes for just five from his second over as the pair are content to knock the medium-pace about.
Derbsyhire 66-5 (target 161)

What a bowler Simon Harmer is - he's looked a threat every single ball. It's a dry surface already and he's the bowler that has extracted the most turn.
Hughes 12, Critchley 1
Matt Critchley survives Simon Harmer's hat-trick ball.
But is that the over that has won this game for Essex?
Harmer now has 3-6 off his two overs.
Derbyshire 66-5 (target 161)
Simon Harmer is on a hat-trick!
Anuj Dal skips down the track, misses his first ball and it smacks into the timbers.
Derbyshire are reeling.
Derbyshire 66-4 (target 161)
BEAUTY!
Simon Harmer gets one to grip and turn away and it beats Leus Du Plooy all ends up as the ball clatters into the stumps.
Make that two wickets in two...
Du Plooy 9, Hughes 11
Aaron Nijjar gives the Derbyshire batsmen nothing off his second over as they milk him for six singles.
The Falcons need another 96 from 78 balls. Where's your money?
Derbsyhire 59-3 (target 161)

Essex will be pleased with how they have started in terms of picking wickets up in the Powerplay - it's so crucial in this format of the game to not let the batters get on top of you.
Du Plooy 5, Hughes 8
Alex Hughes follows up his opening four with another cut to the rope off Ravi Bopara.
11 come from the over.
That's the Powerplay done - probably just shaded by Essex.
Du Plooy 3, Hughes 4
What a way to get off the mark!
Ravi Bopara drops short and Alex Hughes laces him through point for four.
Derbyshire have lost wickets, but they're up with the required run rate.
Du Plooy 3, Hughes 0
14 come off Aaron Nijjar's first over, but Essex will take that after it brought the wicket of the dangerous Wayne Madsen.
Ravi Bopara is entrusted with the final over of the Powerplay.
Derbyshire 48-3 (target 161)
Bowled him!
Wayne Madsen tries to sweep Aaron Nijjar for a fourth boundary in the over but misses and the ball clatters into leg stump.
Derbyshire are three down and in a bit of trouble.
Madsen 17, Du Plooy 3
Essex spinner Aaron Nijjar comes on and is greeted with disdain by Wayne Madsen.
The Derbyshire batsman sweeps him for four, then launches him over mid-wicket for a huge six, followed by another four.
But HOLD ON...
Derbyshire 34-2 (target 161)

Ex-England batter on BBC Radio 5 Live Sports Extra
Derbyshire don't have the super big hitters but they seem to operate as a unit.
If Wayne Madsen, who has the experience with that cool calm head, can bat 10 overs that will really help support Derbyshire to chase that total down.
Derbyshire 34-2 (target 161)
Luis Reece was smacking the ball to all parts at the start of Derbyshire's chase, but Adam Wheater had other ideas...
Madsen 3, Du Plooy 3
That's now two overs dominated by Derbyshire, and two by Essex.
This is very much the Eagles' six balls. Simon Harmer concedes just four off his first and picks up the wicket of Billy Goldeman.
Derbyshire 30-2 (target 161)
Simon Harmer spins one past the bat of new man Leus du Plooy and they're checking the stumping.
Not out. It's another fine delivery from the South African.
