A century from Jonathan Bairstow has put Yorkshire into a commanding position in their LV County Championship clash with Somerset.

At tea on day 1 the Tykes had reached 262 for four, with Bairstow unbeaten on 103.

It is only the second time the 21 year-old has been past three-figures in the first-class game, with his debut 100 coming against Nottinghamshire earlier this month.

Gary Ballance, who is on 45 not out, has also impressed during the afternoon session, with Yorkshire adding 153 runs for the loss of only one wicket.

Captain Andrew Gale was the man out, for 30.
