Northamptonshire Steelbacks found themselves on the back foot as Somerset openers Thomas Rew, whose 57 from 30 was his maiden T20 half-century, and Will Smeed racked up a quickfire partnership of 104.
Daniel Sams, with an unbeaten 48 from just 16, then propelled the visitors to a commanding 223-4.
The Steelbacks were in contention at 65-1, but Lewis Goldsworthy (3-32) wrecked their hopes with three wickets in an over and fellow left-armer Josh Thomas then took centre stage with a career-best 4-6 in three overs as Somerset rolled their hosts for 118.
Gareth Roderick top-scored with 71 from 43 in Worcestershire Rapids‘ total of 161-9 at Cardiff, with Glamorgan appearing well-placed after a strong effort by spinners Ben Kellaway (3-24) and Mason Crane (2-24).
However, the Rapids’ spin contingent responded well as Usama Mir (2-17) and Fateh Singh (3-17) kept up the pressure on Glamorgan, with Beyers Swanepoel taking 3-36. Despite Kellaway’s 43 from 26, the home side were bowled out for 146.
Warwickshire Bears all-rounder Beau Webster maintained his status as the Blast’s leading run-scorer with 78 from 44 against former side Gloucestershire to set up his side’s 30-run victory at Edgbaston.
Webster was backed up by Dan Mousley, whose unbeaten 72 included six sixes as the Bears posted 203-5 before restricting Gloucestershire to 173-6, with spinner Usman Tariq taking 3-12.
