Worcestershire suffered a six wicket defeat after being dismissed for 141 in a Royal London One-Day Cup clash with Yorkshire Vikings at Headingley.

Joe Leach, with an unbeaten 43, and skipper Daryl Mitchell (33) were the main contributors with the bat for Worcestershire who were bowled out with 6.4 of their 50 overs remaining.

Leach and Mitchell McClenaghan featured in the highest stand of the Worcestershire innings – 39 in 6.4 overs – for the 10th wicket.

McClenaghan was Worcestershire's most successful bowler with 3-57 from eight overs as the Vikings reached their target in 30.2 overs.

England paceman Tim Bresnan (4-28) and leg spinner Adil Rashid (3-21) did most of the damage when Worcestershire batted.

Mitchell opted to bat after winning the toss and collected the first boundary through the covers off Bresnan.

Richard Oliver then turned Jack Brooks past deep square leg for four but then was adjudged lbw by his next delivery for five.

Mitchell looked in good form and straight drove Bresnan for four as Worcestershire reached 42-1 at the end of the first powerplay.

The visitors immediately took their second powerplay and were on the receiving end of a spell of 3-0 in six overs from Bresnan.

Tom Fell survived an appeal for caught behind off Bresnan but in the same over he was bowled by a ball which came back in and hit the top of off stump for 10.

Bresnan's next delivery accounted for Alexei Kervezee (0) with Alex Lees taking a juggling catch at first slip.

Tom Kohler-Cadmore survived the hat-trick ball in Bresnan's next over but after making a single a delivery clipped the toe end of his bat and Adam Lyth held onto a excellent catch at second slip with the total on 48-4.

Mitchell made an accomplished 33 off 48 balls with four boundaries before he was adjudged lbw to Matthew Fisher.

Rashid bowled keeper Ben Cox (10) around his legs to make it 67-6.

Ross Whiteley, who had made two half centuries in the opening three One-Day Cup games, hit a couple of boundaries but he fell lbw to Rashid for 13 at 78-7.

Brooks returned to the attack and Shaaiq Choudhry (0) was caught behind off the sixth ball of his first over back in the action.

Rashid collected his third wicket when Jack Shantry (7) was stumped after coming down the wicket.

There was last wicket defiance from Leach, who hit Richard Pyrah for successive boundaries, and McClenaghan who returned to the One-Day Cup side in place of Charlie Morris.

McClenaghan played the scoop shot and reverse sweep to good effect in supporting Leach.

He was finally bowled by Bresnan for 16 to leave Leach unbeaten with five fours in his 63 ball knock.

McClenagan then shared the new ball with Shantry and he broke through in his first over when Lees (3) was caught by Fell at long on after trying to hit over the top.

Kohler-Cadmore had to go off for treatment after an edge from Kane Williamson caught him on the finger in the slips in McClenaghan's second over and was replaced in the field by 12th man Brett D'Oliveira.

Williamson hit three boundaries in an over from international colleague McClenaghan as Yorkshire reached 38-1 by lunch.

Leach produced a fine delivery to have Adam Lyth (14) caught behind and then McClenaghan ended Williamson's knock on 43 when he was trapped lbw with a ball which cut back.

McClenaghan picked up a third wicket when Andrew Gale, having struck seven fours in his 21 ball 29, was bowled via the inside edge at 100-4 but it was Worcestershire's last success.
