|LV= County Championship Division One, Taunton|
|Somerset v Lancashire 221-6|
|Somerset 2 pts, Lancashire 1 pt|
Paul Horton's century provided the backbone of Lancashire's innings as Somerset controlled day one at Taunton with an all-round bowling performance.
The opener hit 21 fours in his 140, including a pull off George Dockrell (1-48) to bring up his ton, having been dropped at first slip on 81.
Lewis Gregory (2-38) trapped Horton lbw, while Alfonso Thomas was the pick of Somerset's bowlers with 2-27.
Tom Smith's hard-fought 13 off 67 balls helped Lancashire to 221-6 at stumps.
It was Horton's first triple-figure score of the season and proved vital for a struggling Lancashire side, who currently sit in eighth place in Division One, with the other five wickets falling for a combined 58 runs.
The away side, who are 26 points behind joint leaders Yorkshire and Nottinghamshire, have claimed the third lowest number of bowling bonus points so far this year.
BBC Radio Lancashire's Scott Read:
"An enjoyable and intriguing day's cricket at the County Ground with the game nicely balanced at the end of the first day.
"Lancashire's decision to bat first seemed to be a bold one on a green-looking pitch with humid conditions but it is looking like a pitch that might prove to be tough to bat on last.
"Paul Horton's superb knock was the clear highlight for Lancashire who are now starting to find runs from all around the team.
"He's the fourth different Red Rose player to reach three figures in the last three innings and a total of 300-plus should be very competitive."
BBC Radio Somerset's Anthony Gibson:
"I am not sure how good a score Lancashire's 221-6 really is on a slow, slightly tacky pitch which wasn't much fun for either batsmen or bowlers - or for spectators, as Lancashire ground along at 2.6 runs per over.
"Still, a sun-baked crowd did have the moment many of them had come for - Jos Buttler's return to Taunton. He was cheered all the way to the wicket, Alfonso Thomas jokingly attempted to run him out backing up and he hit two trademark sixes before being bowled by Lewis Gregory for 18.
"There was no doubt about the real star of the day - Paul Horton, whose assured, skilful 140 has given Lancashire parity, at the very least."
