    IT'S ALL OVER AT TAUNTON

    Derbyshire 74 all out (11.2 overs), Somerset 265-5

    Derbyshire have lost to Somerset by 191 runs - and it's by some margin a record defeat in English T20 cricket.

    It beats the 144-run loss suffered by Worcestershire at Edgbaston just 15 days ago - and jubilant Somerset are heading for Finals Day for an eighth time.

    But, for Derbyshire, this has been a total embarrassment.

  3. Derbyshire 73-9 (11.1 overs), Somerset 265-5

    A no ball - and Derbyshire avoid getting their lowest ever T20 score.

  4. Derbyshire 71-9 (11 overs), Somerset 265-5

    Four off that over. Benny Green to continue.

  5. wicket

    WICKET - Aitchison run out 2

    Derbyshire 68-9 (10.2 overs), Somerset 265-5

    Ben Aitchison goes in a comic run-out mix-up.

    Derbyshire still short of their lowest ever score in T20 - of 72.

  6. Derbyshire 66-8 (10 overs), Somerset 265-5

    Ben Aitchison at least has the sense of dignity about him to avoid the hat-trick.

  7. wicket

    WICKET - Watt c Banton b Green 0

    Derbyshire 65-8 (9.5 overs) v Somerset

    Benny Green on a hat-trick as Mark Watt skies to square leg and Tom Banton runs to take the catch.

  8. wicket

    WICKET - Hughes c Lammonby b Green 12

    Derbyshire 65-7 (9.4 overs) v Somerset

    Alex Hughes is the next to go.

  9. Derbyshire 61-6 (9 overs) v Somerset

    New man Mattie McKiernan introduces himself with a boundary off Lewis Gregory.

  10. wicket

    WICKET - Madsen c van der Merwe b Gregory 14

    Derbyshire 54-6 (8.2 overs) v Somerset

    Somerset celebrateRex Features

    Derbyshire are folding like a pack of cards.

    Wayne Madsen drives straight to mid off.

    Roelof van der Merwe takes trhe catch with arms above his head.

  11. 50 runs

    50 up for the Falcons

    Derbyshire 53-5 (8 overs) v Somerset

    Little victories. 50 up at least in that over for Derbyshire.

    Just another 213 needed. Off 12. With half the batting gone.

    Not the moment to glance over and see what the DLS is.

  12. wicket

    WICKET - Guest b Gregory 0

    Derbyshire 43-5 (6.3 overs) v Somerset

    Things are just going from bad to worse for Derbyshire.

    Brooke Guest goes second ball, bowled by Lewis Gregory.

    Alex Hughes is the next to try his luck.

    Let's just hope that George Scrimshaw can bat as well as he bowled earlier. He's their only hope!

  13. wicket

    WICKET - Cartwright c sub (Bartlett) b Siddle 10

    Derbyshire 42-4 (6 overs) v Somerset (265-5)

    Peter SiddleRex Features

    A fourth Derbyshire wicket goes down as George Bartlett pouches a catch off Peter Siddle.

    Brooke Guest comes in.

  14. Derbyshire 36-3 (5 overs) v Somerset (265-5)

    10 off that Craig Overton over.

    The main job for Wayne Madsen and Hilton Cartwright now is keeping things respectable.

    It's only 15 days since Worcestershire suffered the worst defeat in this competition, by 144 runs at Edgbaston, to the Birmingham Bears. That must be their first target.

    Peter SiddleRex Features

    Derbyshire are just falling apart.

    Psychologically they were pulverised when they chose to bowl and field first tonight.

  16. wicket

    WICKET - Du Plooy c Banton b Siddle 0

    Derbyshire 26-2 (3.5 overs) v Somerset

    Leus Du Plooy is out just a ball later.

    Two wickets in three balls for Peter Siddle.

    New man is Hilton Cartwright.

  17. ouch!

    Painful blow for Leus du Plooy

    Derbyshire 26-2 (3.4 overs) v Somerset

    Painfiul blow for Derbyshire skipper Leus du Plooy, who is hit on the left elbow.

    He needs treatment - but he looks in trouble.

  18. wicket

    WICKET - Reece c Rossouw b Siddle 13

    Derbyshire 26-2 (3.3 overs) v Somerset

    Luis Reece is the second man to go.

    Leus Du Plooy is the new man.

  19. Derbyshire 14-1 (2 overs) v Somerset (265-5)

    Dave Fletcher
    BBC Radio Derby Sport

    It's quite a subdued atmosphere here inside the County Ground here now. It's unsurprising as we all know the result. We are just waiting for the end.

  20. Derbyshire 14-1 (2 overs) v Somerset (266-5)

    Only five off the second over, which ends with a turned-down LBW review against Luis Reece.

    Craig Overton stays on for a second over.

    Atmosphere now a little subdued. Few in the Taunton crowd give the visitors any chance of even getting close here.
