County Championship D2, Taunton, day four: Middlesex 600-4d & 209-2 drew with Somerset 850-7d
Middlesex 10pts, Somerset 10pts
Somerset and Middlesex played out an inevitable draw as records tumbled.
Resuming at 683-5, captain Justin Langer was bowled early on for 315, which was 27 short of the Somerset record which he set himself last year.
But Peter Trego (130) and Sam Spurway (44 not out) helped them set a new highest total at Taunton by any team before Langer declared at 850-7.
In reply, Owais Shah (72) and Ed Smith (103) put on an unbroken 184 for the third wicket as Middlesex made 209-2.
Although the game had long ago ceased to have any likelihood of a result, the home supporters would have enjoyed watching Somerset easily beat their previous highest first-class score of 705-9 declared against Hampshire in 2003.
The Taunton ground record of 801 by Lancashire in 1895 was also surpassed, as was the previous highest innings total for a Championship match involving Somerset - 811 by Surrey at The Oval in 1899.
Langer's marathon innings (574 minutes, 412 balls, 38 fours) ended 20 minutes into the day's play when he was yorked by Tim Murtagh.
It was a fifth first-class century for Trego, whose 130 came off 130 balls and included 12 fours and three sixes.
But after losing Ben Hutton and Nick Compton with the score just 25, Middlesex were in cruise control as the match finally ended with 1,659 runs plundered over the four days for the loss of just 13 wickets.
"I felt good out there, but I have been batting well for some time now, so it's nice to cash in and get the rewards," Langer told Somerset's website.
"I wasn't thinking much about the 342, as records are something to look back on towards the end of your career."
