YORKSHIRE suffered their first Royal London one-day Cup defeat of the season as they failed to chase 343 against Worcestershire at New Road today.

The Vikings have been replaced at the North Group’s summit by the Rapids, with their record standing at three wins and this 51-run defeat.

Former Yorkshire under 15s batsman Tom Kohler-Cadmore hit 118 off 119 balls to get the hosts off to a flyer before Yorkshire lost wickets too regularly on the way to 291 all out inside 47 overs.

Peter Handscomb’s 77-ball 88 was Yorkshire’s top score and his List A career best.

Former Rapids captain Daryl Mitchell also impressed with 69 and three wickets with his medium pacers.

Although this result is no disaster in terms of qualification from the North Group, it does dent White Rose hopes of finishing top and claiming an automatic home semi-final.

Worcester’s innings was a strange one after they had been invited to bat by Gary Ballance, who was without his five England players.

Even though this was the Rapids highest ever List A score against a first-class county here, they could have posted even more.

They lost six wickets for 95 to slip from 175-1 in the 27th over to 270-7 in the 43rd and later their last three wickets in the 49th over to Matthew Waite.

Steve Patterson claimed 3-67 from 10 and Waite’s 4-65 from 9.5 overs.

Kohler-Cadmore shared 135 inside 22 overs for the first wicket with Mitchell as Yorkshire’s bowlers erred.

The other key partnership in the innings proved to be a blistering eighth-wicket stand between captain Joe Leach and Australia seamer John Hastings, who shared 67 in 5.5 overs.

Leach hit 41 and Hastings 33 before both fell, bowled and caught at long-on, to Waite in the 49th over.

Yorkshire were up with the run-rate for the majority of their chase.

It had started at close to seven an over, and they had reached 70-0 inside the 10th over.

However, they lost four wickets for 63 runs to slip to 133-4 in the 21st over, with Alex Lees, Will Rhodes, Adam Lyth (59) and Ballance all falling.

Hastings had Lees caught behind and Rhodes caught at point, while Lyth was trapped lbw by a slower ball from Leach and Ballance was run out looking for two.

Even though wickets fell regularly, Yorkshire were still in the game with Handscomb at the crease.

He reached 50 off 42 balls before Jack Leaning offered a return catch to medium pacer Mitchell as the score fell to 182-5 in the 28th.

The Vikings reached the 30-over mark at 197-5, needing 146 more.

The departure of Tim Bresnan, caught at deep mid-wicket off Mitchell as the score fell to 204-6 in the 32nd, proved crucial given he was Yorkshire’s last recognised batsman.

And, with runs not coming as freely in the few overs afterwards, the rate started to become an issue.

Waite and Handscomb, the latter bowled by Ed Barnard, both fell with the score on 241 to leave the visitors eight down in the 41st. By that stage, Yorkshire’s hopes had gone.

Azeem Rafiq was run out and Patterson bowled by Josh Tongue either side of a couple of late sixes for Matt Fisher in a career best unbeaten 36.
