Ryan Sidebottom produced a four-wicket burst before Yorkshire were frustrated by Somerset’s 10th-wicket pair on day two of the rain-hit LV= County Championship match at Headingley.
Former England paceman Sidebottom reduced the visitors to 215 for nine with a lively spell of four for 14 in eight overs, but Alfonso Thomas and Steve Kirby then added 50 for the last wicket as Somerset were all out for 265.
The partnership would not have got going if Thomas’ edge off Ajmal Shahzad had been taken by wicketkeeper Jonny Bairstow, but neither he nor Adam Lyth at first slip moved, the ball bisecting them on its way to the boundary.
Somerset were finally all out in 74 overs, leaving lowly Yorkshire to negotiate nine overs. They reached the close on 20 without loss.
For the second day running, rain prevented any play during the morning session and it was 1.45pm before Somerset were able to resume their first innings on 140 for three.
Further interruptions for bad weather meant that a total of 52 overs in the day were lost.
