Ongoing pitch investigation'
The amount of turn in the pitch at Taunton has caused controversy and it has been assessed by ECB cricket liaison officer (CLO) Wayne Noon, as well as umpires Alex Wharf and Michael Burns.
Shortly after the completion of the game, it was announced that the pitch had been graded "below average" and this rating does not normally carry a points deduction.
However, this does not mean that Somerset are in the clear with Noon revealing that investigations will continue.
"I've marked the pitch below average for excessive spin on days one and two," he said. "Days one and two it [the bounce] was fine, the odd one from the spinners on day three might have kept a bit low, but at no stage was there any thought of any unevenness.
"The criteria says it's not how it looks, it's how it plays. In my opinion and other people I've asked for their opinion, we've come to the same conclusion that it's excessive turn.
"There's going to be an investigation tomorrow. Phil Whitticase, another CLO, comes in. He'll conduct an investigation and he will go through my findings and speak to both umpires, both captains and the groundstaff.
"He could downgrade it, he could upgrade it, that's entirely up to him. He looks at the evidence and he makes his own call."
