Two more down for Somerset, who are in real trouble now.
James Hildreth (13) and Lewis Goldsworthy (1) fall in the space of three deliveries.

Lancashire Lightning 56-0 (6 overs) v Northamptonshire Steelbacks 142-8 (20 overs)
It's another very good powerplay for Lancashire, with some poor fielding contributing to Northants' downfall.

McManus finishes 60 not out off 36 balls after some scampered twos off Jack Brooks' final over.
