No indication yet of how much bowling Keith Barker may be able to do in the remainder of this match, having developed a sore back while batting yesterday.  He spent a short while off the field last evening but is on the field this morning, which is probably an indication that he is okay.  For the moment, though, Ryan Sidebottom has bowled at the pavilion end, with Jeetan Patel continuing to exploit this turning pitch and making it hard to score, off him at any rate. Somerset’s lead is 231 and Marcus Trescothick has completed a half-century off 102 balls with seven fours.
