Alviro Petersen led the way with an unbeaten century as Somerset took the attack to Lancashire on the first day of the LV= County Championship Division One clash at Emirates Old Trafford.
Petersen held firm on 109 not out - his first championship century of the summer - and was ably assisted by Nick Compton’s 91, as the visitors racked up an impressive 312 for three in Manchester.
Compton batted with typical assurance but fell an agonising nine runs short of a ton when he was trapped in front by a ball from Kabir Ali towards the end of the day.
Somerset captain Marcus Trescothick won the toss and chose to bat, and it looked to have been an inspired decision as his side scored runs freely.
The former England batsman saw off the opening overs with Johann Myburgh before the latter fell in the 17th, when he was trapped lbw by Tom Smith for 35.
That brought Compton to the crease and the duo looked to be settling in only for Trescothick to be bowled by Simon Kerrigan shortly after making his half-century, leaving Somerset 96 for two.

But the combination of Compton and Petersen proved to be altogether more fruitful, with the pair putting on a stand of 193 for the third wicket.
The partnership was broken when Kabir trapped Compton lbw in the 85th over - reward for some probing work by the seamer - with a century in sight.
Petersen had already gone through to the landmark by this point, his hundred coming up off 146 balls in 196 minutes, with 10 fours to his name.
The South African made the Lancashire bowlers toil in the field with Smith's 1-45 off 13 overs the most economical figures of the day.
Peterson will resume on tomorrow alongside Alex Barrow, who is 14 not out.
