Match report
Peter Handscomb's maiden List A century fired Yorkshire to a 15-run Royal London One-Day Cup win over Derbyshire at Headingley.
The Australia batsman continued his excellent form in 50-over cricket this season with 140 off 112 balls as Yorkshire amassed 349 for seven.
In reply, Wayne Madsen hit 112 off 104 but it was not enough as spirited Derbyshire made 334 for eight, although they never looked like winning.
Yorkshire's fourth victory in five matches fired them back to the top of the North Group.
It was Yorkshire's highest List A score at Headingley - beating the 335 for five they posted against Durham last week - and the biggest total Derbyshire had ever conceded.
The signs were there almost immediately that the Vikings were on for a huge score, despite losing the toss.
Opener Alex Lees pulled his first ball for six off Ben Cotton in the second over, with Yorkshire reaching the 10-over mark at 79 for two.
Handscomb shared partnerships of 81 for the third wicket with Jack Leaning (39) and 156 inside 21 overs for the fourth wicket with captain Gary Ballance, who hit 63 off 56.
The Victorian has now posted at least 40 in each of his five innings in the competition and is the leading run-scorer with 407.
Handscomb, dropped on 135 at deep cover, was one of four wickets to fall inside the last six overs of the innings.
He was stumped off Sri Lanka leg-spinner Jeevan Mendis, who also got Ballance on the way to two for 59 from 10 overs.
Derbyshire then lost captain Billy Godleman and Shiv Thakor inside the first eight overs of their chase.
Godleman was caught at second slip off Tim Bresnan before Thakor was bowled by Coad as the score slipped to 31 for two.
Ben Slater hit two fours and a pulled six off all-rounder Matthew Waite's seamers in the 16th over. But Waite got his revenge towards the end of the same over when he forced the left-hander to play on for 43.
When Matthew Fisher had Alex Hughes caught behind in the next, the game was pretty much up for the visitors at 87 for four.
Derbyshire's fifth wicket was that of Mendis when, in the 25th over, he swept left-arm spinner Karl Carver's fourth ball to deep midwicket.
From there, the match drifted as Madsen managed to delay Yorkshire with some eye-catching strokeplay, most of which came after he had reached his fifty.
He reverse swept Carver for six and four in the 33rd over during a 117-run stand with Daryn Smit.
Madsen reached three figures off 96 balls as the score moved to 233 for five with 10 overs left, with the visitors needing 117 more.
He fell shortly afterwards as Coad struck twice in the 43rd over, with Madsen miscuing to cover and Luis Reece to mid-on to leave the visitors 246 for seven.
Matt Critchley hit 49 off 21 balls to make the game look closer before becoming Coad's fourth victim in the last over, with Smit finishing unbeaten on 77.
