A review of Friday's action in the Vitality Blast, as Yorkshire thrashed Birmingham Bears and Gloucestershire got the better of Glamorgan.
A powerful Yorkshire batting performance led them to a high-scoring but comfortable Vitality Blast win over Birmingham Bears at Emerald Headingley, their fourth in six North Group matches.
The Vikings amassed 226 for eight before a 40-minute rain delay revised the Bears target to 208 from 18 overs, only for them to post 176 for four.
Vikings opener Tom Kohler-Cadmore smashed 73 off 30 balls to underpin a total including 49 for New Zealand captain Kane Williamson.
The Bears conceded 200 plus for the fourth game running on the way to a 31-run defeat on DLS.
Aaron Finch and Jason Roy hurried Surrey to a nine-wicket win against Somerset with a spectacular opening partnership of 69 in just 3.5 overs at the Kia Oval.
Finch's 43 not out from just 21 balls included three sixes and four fours while Roy's 28 off 11 featured two sixes and three fours, and Surrey overhauled Somerset's 99 for six with an almost contemptuous ease in a match shortened by bad weather to 10 overs per side.
For Surrey it was a third win from six south group games, while Somerset suffered a third defeat in six despite their captain, Lewis Gregory, thumping 50 not out from 24 balls with four sixes and three fours.
A half-century from Billy Godleman underpinned by some explosive hitting by Hardus Viljoen helped Derbyshire Falcons maintain their current mini-revival by overhauling a modest total by Leicestershire Foxes.
Godleman recovered from running out the Falcons' dangerman Calum MacLeod off the second ball as the Falcons chased a target of 150, his unbeaten 57 steering his side to back-to-back wins.
Notts Outlaws regained their winning touch to down North Group leaders Lancashire Lightning in their rain-interrupted match at Trent Bridge.
Lancashire, off the back of five straight victories, had been challenged to score 156 from 15 overs but could only reach 139 for eight, giving the defending champions the points by a margin of 16 runs under the DLS method.
Earlier, Notts posted a score of 196 for nine, despite losing four wickets inside the opening six overs.
Martin Guptill struck 102 from only 38 balls as Worcestershire demolished Northamptonshire at Wantage Road, chasing 188 to win by nine wickets with 6.5 overs to spare.
Guptill's fourth domestic T20 century and Joe Clarke's 61 not out from 33 balls made mincemeat of the target to give Worcestershire their fifth victory in this season's Vitality Blast.
Michael Klinger struck a superb unbeaten half-century as Gloucestershire beat neighbours Glamorgan by 30 runs at Cheltenham.
The veteran Australian hit 77 not out as the hosts posted an imposing 197 for six in front of a sell-out crowd at the College Ground.
Overseas signing Andrew Tye then took three for 17 as Glamorgan subsided to 167 for nine in reply, leaving Gloucestershire in top spot in the South Group with four wins from six games.
Kent's clash with Sussex was abandoned 11.2 overs into the Spitfires' innings as the hottest day of the year ended in a crescendo lightning, thunderstorms and a sudden deluge of rain over Canterbury.
For the second time in a week, the early South Group leaders had proceedings called off for inclement weather following last Friday's abandonment against Surrey after the visitors had scored a mammoth 250 for six.
This time, Kent had fared much better in reaching 99 for two when the skies darkened and the heavens opened, leaving umpires Jeremy Lloyds and Chris Watts to take the players from the field for the sides to share a point apiece.
