MARCUS Trescothick equalled a Somerset batting record on the second day of their Specsavers County Championship match against Nottinghamshire at Trent Bridge.

Trescothick scored his 49th first-class century for the county - and first in Nottingham - in making 117 not out as the visitors reached stumps on 244 for three, trailing the hosts by 157 runs.

In doing so, former England opener Trescothick matched Harold Gimblett's total of centuries for the west country side.

In 17 previous matches on the ground, stretching back to 1997, the 40-year old left-hander had not reached three figures for either his county or country but brought up the milestone in just 122 deliveries, with 19 fours and a six.

Notts had batted on until being bowled out for 401, just after lunch, with Steven Mullaney having departed for 165.

Somerset openers Trescothick and Johann Myburgh made a great start, putting on 100 in just 21 overs.

Their partnership had moved on to 123 when Myburgh fell for 54, bowled by the leg-spin of Imran Tahir.

Trescothick, who made a pair in last season's corresponding fixture, brought up his 50 from 60 balls and then shared in a second-wicket stand of 101 with Chris Rogers.

On reaching 20, Rogers also had reason to celebrate as he brought up 25,000 career runs. The Australian looked untroubled throughout his stay, until casually flicking Harry Gurney down the leg side for 48.

Gurney was then gifted a second wicket as James Hildreth, inexplicably, left alone a delivery from the paceman that uprooted a couple of stumps.

Earlier in the day, Nottinghamshire lost their last six wickets for only 90 runs, including that of Mullaney, who had resumed on 161.

Mullaney clipped his first ball of the day down to the fine-leg fence to equal his career-best score of 165. Without any further addition he wafted loosely outside his off stump and Ryan Davies dived to his right to take the catch.

Samit Patel stroked three boundaries in his 15 but then mistimed a pull into the hands of Hildreth at midwicket.

Luke Fletcher, who arrived at the crease as nightwatchman on the first evening, batted on for a further 90 minutes before falling to Jim Allenby for 32.

Next ball, from the other end, Chris Read, 15, was also struck on the pads and sent on his way, giving Jack Leach his third wicket of the innings.

Brett Hutton and Gurney fell in quick succession after lunch, both edging Craig Overton through to the wicketkeeper.

Trescothick said afterwards: "I'm delighted, the last couple of weeks have been fantastic. It's been brilliant to go past Sir Viv (Richards), close in on Harold's record and now equal it.

"More than that, it's my first hundred here at Trent Bridge. I've had some dark days here. Last year I bagged a pair, so it's nice to come back and get a hundred this time."
