Shadab Khan is the new man and works his first ball to long-on.

Five to go, where can Yorkshire get to?

150 still getable.

Dan Worrall is back.

Tom Kohler-Cadmore find a boundary first ball, then has a mighty swipe at the fourth ball but only gets a bottom edge to deep midwicket.

He then aims at the pavilion over long-off and just clears the fieldsman on the fence for six.

Just beginning to run now Yorkshire.

Yorkshire 82-2

Ah here we go, Tom Kohler-Cadmore clears the front leg and swings clean over Dan Moriarty's head for the first six of the night.

Then later in the over David Willey steps to leg and whacks one into the pavilion.

Have this pair decided it's time to have a dip?

Sunil Narine finally enters the fray and will surely bowl four of the remaining overs.

He almost strikes first ball as Dave Willey tries to go down the ground but squirts a wild edge just short of deep cover.

Tom Kohler-Cadmore then gets a thin edge to the third man fence.

The rest of the over it just worked around and Yorkshire reach halfway going along very patiently indeed.

Bazball this is not.

But then you're often dictated to by conditions.

Comes back okay but eight from the over - best set so far for Yorkshire.

Will Jacks is bowling himself out here and why not.

They'll be thinking it may not need to many to be in the game here.

Jacks finishes with 1-20. Super Stuff.

Gus Atkinson with a second over and last of the powerplay.

Just three singles from four balls.

Then a sharp bumper is too quick for David Willey and it bounces over Ollie Pope and away for four byes.

A patient first six with two big wickets.

A pulled single ends the over.

Finally a boundary as Will Jacks, having a second over, drops short and Tom Kohler-Cadmore pulls past square leg to the fence.

Awful start for Yorkshire.

These look like tricky conditions and no surprise Surrey have fielded first.
