Stunning hitting by Aaron Finch and Jason Roy saw Surrey cruise to a remarkable nine-wicket win over Middlesex in the Vitality Blast as they chased down a target of 221 with four overs remaining.
Australia batsman Finch finished on 117 not out from 52 balls, while England opener Roy made 84 from only 37 deliveries before holing out in the 14th over at the Oval.
Paul Stirling’s spectacular 58-ball 109 for Middlesex was overshadowed as Finch and Roy plundered an astonishing 194 for Surrey’s first wicket – scoring 98 in the initial six-over powerplay alone – to spearhead a victory achieved with a barely believable 24 balls to spare.
Johann Myburgh also reached three figures to fire Somerset to a resounding 10-wicket win over Essex.
Myburgh plundered an unbeaten 103 off 44 balls, which included three sixes and 16 fours, as Somerset knocked off Essex’s modest 135 for nine inside 12 overs.
Tom Banton finished 29 not out while Jamie Overton and Jerome Taylor did the damage with the ball, taking three wickets apiece.

Alex Davies had earlier made a career-best 94 not out in the home side’s 190 for five but it was not enough.
Timm van der Gugten held his nerve as Glamorgan earned a two-run win over Gloucestershire.
