Three of Sunday's scheduled games in the Vitality T20 Blast were abandoned due to rain.
Destructive half-centuries from Peter Trego and Lewis Gregory led Somerset to a total of 229 for six and a 38-run Vitality Blast win over Middlesex under the Duckworth-Lewis system at Taunton.
Trego smashed 60 off 31 balls, including 24 off an over from Ashton Agar, to relaunch his side's innings after left-arm seamer Tom Barber had taken three wickets in an over to reduce them to 29 for three.
Skipper Gregory then took up the attack with an even more destructive 62 off 26 deliveries, receiving good support from Corey Anderson (41 not out) as the Middlesex bowlers were dispatched to all parts of the County Ground.
In reply, the shellshocked visitors had made 88 for four from 10 overs when rain interrupted their innings for the second time.
They faced a revised target of 213 from 18 overs, with a required run-rate of around 16 an over, and, despite a 29-ball fifty from Stevie Eskinazi, fell well short at 174 for six.
Worcestershire Rapids and Lancashire Lightning suffered weather frustration as their top-of-the-table clash was abandoned without a ball being bowled.
The two teams had gone into the eagerly-anticipated encounter at Blackfinch New Road level on 10 points along with Durham Jets.
But persistent rain from early morning resulted in umpires Neil Bainton and Russell Warren calling off play at 4.20pm.
The game between Glamorgan and Kent at Sophia Gardens was also abandoned as a draw without a ball being bowled, with the teams awarded a point apiece.
Following heavy overnight rain, the weather relented during the morning and there were hopes that the game would start at 2.30pm, the scheduled start, but the rain returned and intensified during the afternoon.
The umpires, Neil Mallender and Paul Pollard, made their final inspection mid-afternoon and had no hesitation in calling the game off at 3pm.
There was also an enforced draw between Sussex Sharks and Hampshire, again without a ball being bowled.
