Dawid Malan starred while Jos Buttler endured frustration as Yorkshire claimed a 15-run victory over Lancashire in the Vitality Blast Roses clash at Headingley.

After Malan hit a superb 83 off 50 balls in the Vikings’ 195 for six, England colleague Buttler made just one in his first Lancashire appearance of the summer, caught at mid-off from the off-spin of Dom Bess seven balls into the Lightning’s pursuit.

They subsequently finished on 180 for eight, with Ben Mike and Dawid Wiese having each claimed two for 31.

Also in the North Group, a career-best unbeaten 109 by Wayne Madsen set up Derbyshire for a first win of the campaign at Leicestershire, who ran them close but fell three runs short of their target.

Madsen’s brilliant 61-ball innings, which contained 12 fours and four sixes, helped the Falcons post 189 for five after being put in, Tom Wood making 37 from 24 balls and Brooke Guest 25 not out from 20.

The Foxes, who have lost all of their opening four matches, put up a decent fight, with Colin Ackermann (59 not out) and Rehan Ahmed (28 not out) scoring 58 off the last 31 balls after Rishi Patel’s 44 – but it was not quite enough as they closed on 187 for five.

In the South Group, Essex thrashed Sussex by 25 runs at Hove with captain Simon Harmer taking a hat-trick.

Harmer struck with his first three balls after coming on in the third over as Essex easily defended a target of 164. After losing Ravi Bopara in the first over of their reply, the hosts then saw Harmer dismiss Tom Alsop, Shadab Khan and Michael Burgess to leave them at 15 for four with their chase effectively over before it had begun.

They ended up dismissed for 138 with eight balls unused, Harmer finishing with figures of four for 28.

Essex’s earlier 163 for seven featured 55 from Feroze Khushi, while Shadab took three wickets.
