Bright morning for Somerset
Somerset enjoyed a much brighter morning – only for the rain to arrive before lunchtime and wipe out the entire final two sessions at Taunton.
While play was possible, Somerset took five wickets for 32 runs in 21 overs to cut Lancashire down from an overnight 363-4 to 395-9 – still five runs short of maximum batting points with three overs left in which to get them.
In the process, Somerset secured maximum bowling points, aided by a lively spell in which they took three wickets in ten balls, with Vernon Philander living up to his billing as international cricket's man of the moment.
The South African claimed 3-6 from his eight overs, with five maidens, in the morning as he removed Gareth Cross (21), Steven Croft (113) and Saj Mahmood (3).
First he tempted Cross to edge one that Craig Kieswetter caught thanks to a spectacular dive, before, seven balls later, the wicketkeeper pulled off a similarly impressive catch off Pete Trego's bowling to remove Luke Procter (1).
A further two balls down the line, centurion Croft became Kieswetter's third successive victim when he fended at Philander, and, from 363-4, Lancashire were 365-7.
That became 371-8 when Philander removed Mahmood's middle stump – and it was 391-9 when Glen Chapple prodded at George Dockrell's left-arm spin and was caught at slip by James Hildreth for 20.
"I don't think we did a massive amount differently to the day before – we just hit good areas, myself and Vern, and obviously got the rewards," said Trego. "That was pretty pleasing, because we toiled hard (on Thursday) without a great deal of rewards."
