There could be plenty more to come you feel.
Northants v Worcestershire 74-4 (12 overs)
Image source, Getty ImagesThat earlier wicket of Moeen Ali for Northants seamer Oli Stone appears to have come at some cost.
Looks like he celebrated it so wildly that he injured himself in the process and needed some assistance off the park.
Sussex v Surrey 40-1 (4 overs)
Jason Roy has gone bonkers at Hove! The England and Surrey opener has moved to 35 off 17 balls with seven fours.
Surrey have lost Steven Davies for 3 though. Davies was caught by Matt Machan off Tymal Mills.

Time for Leicestershire to rebuild.

Hampshire 71-4 (10 overs) v Glamorgan
It's been quite a night in Cardiff! After a productive couple of overs, it all started to fall apart for Hampshire.
After James Vince departed, Jimmy Adams was the next casualty as he was removed by Dean Cosker for just seven.
Craig Meschede was caught at short mid-wicket soon after and midway through their innings, things aren't looking so rosy for the visitors.
But it's not all good news for Glammy. Adam Wheater is looking suitably more confident at the crease and Shahid Afridi is still yet to bat. Game on!
Birmingham v Durham 11-1 (1.2 overs)
That's a very brief impact innings from Durham's opener Mark Stoneman at Edgbaston.
A six and a four off consecutive balls against Rikki Clarke in the first over.
But then he succumbs to Oliver Hannon-Dalby at the start of the second over and his 11 is all they're getting.

The run-rate has crept up towards nine an over.
Somerset v Essex 178-7 (20 overs)

Somerset v Essex 178-7 (20 overs)
Essex's innings at Taunton is complete.

Michael Hogan does the honours again, this time clean bowling Vince when for many inside the Swalec, it looked as if Vince was about to tee off for another four.
Adam Wheater comes out to the middle. Can he get Hampshire back on track?
