|County Championship Division One, Lord's|
|Close, day two: Somerset 173, Middlesex 321-2|
|Middlesex 6pts, Somerset 0pts|
Chris Rogers and Joe Denly both hit centuries as Middlesex took charge against Somerset on a totally one-sided second day at Lord's.
Resuming on 130-4, Somerset were shot out for just 173, home seamers Tim Murtagh, Gareth Berg and Toby Roland-Jones taking three wickets apiece.
After the early loss of Sam Robson, Rogers (173) and Denly (105no) then put on 245 for the second wicket.
Middlesex ended the day on 321-2, with a commanding 148-run lead.
Less than an hour of play was possible before lunch, but that was enough for Somerset to slip from 130-4 to 155-8, all four wickets falling in the first 10 deliveries of the day, starting with that of Craig Kieswetter, who aimed a loose slash at the very first ball to be caught behind.
Jos Buttler was bowled off an inside edge by Murtagh, who struck again when Craig Overton gloved a seemingly innocuous bouncer through to keeper John Simpson.
With Berg sending Alfonso Thomas's off stump cartwheeling, Peter Trego and George Dockrell survived until an early lunch.
But Dockrell was caught behind off Roland-Jones before Trego, having hit successive fours, looked to put Roland-Jones in the Mound Stand, only to pick out Eoin Morgan at deep square leg.
Following a watchful start, Rogers then set the tone by hitting Gemaal Hussain for four boundaries in eight deliveries and, together with Denly, they set a new record for Middlesex's second wicket in first-class matches against Somerset.
The final session saw the hosts make 207 in 41 overs and, although Rogers was eventually caught on the deep square leg boundary for 173, Denly moved to his second Championship hundred of the season.
VIEW FROM THE COMMENTARY BOX
BBC Radio London's Kevin Hand:
"The first 10 minutes of the day were stunning, starting with a dismissal off the first ball as Craig Kieswetter played a dreadful shot wide outside the off stump - for the first off four wickets in the opening 10 deliveries.
"Temporary captain Chris Rogers then led the onslaught, matching Somerset's score on his own off only 191 deliveries with some shots as aggressive and dismissive as you'll see in the County Championship.
"The pitch is offering a little to the bowlers, but the weather is set to play a big part in the last two days - and Middlesex may consider declaring not long after reaching maximum batting points at 400 to try and ensure time to force victory."
