Somerset were unable to push for victory on the final day at Taunton as their rain-ruined fixture against Nottinghamshire ended in a tame draw.

England off-spinner Graeme Swann took 3-62 in the Somerset innings, including seeing off lower-order pair Abdur Rehman (17) and Gemaal Hussain (29).
With Alfonso Thomas missing from the home attack, Nottinghamshire were able to comfortably erase the deficit. They take seven points while their opponents get six, an unsatisfactory outcome for either with title rivals Warwickshire winning.

After the start of proceedings had been delayed until 2.15pm, Thomas sent back Michael Lumb (16) after a successful lbw appeal that left the batsman a little perplexed.
The same bowler also saw off Alex Hales, though the opener could have no complaints about his mode of dismissal when an ambitious drive only resulted in Marcus Trescothick pouching a comfortable catch at second slip.
Rain intervened at 3.05pm and, although play restarted at 5.25pm, only a further 4.2 overs were possible before another shower brought an early finish.

However that proved to be the final action of the day, yet more rain forcing the players from the field with the score at 18-1.
The wicket took all-rounder Trego's tally in the Championship this season to 41 - only Andre Adams of Nottinghamshire and Tim Murtagh of Middlesex have taken more in the top tier.
