Jack Leaning's maiden century could not prevent Yorkshire crashing to defeat against Essex in a high-scoring Royal London One-Day Cup Group A match at Scarborough.
The 20-year-old struck an unbeaten 111 in his side's 290 for six, but Essex opener Tom Westley and Netherlands international Ryan ten Doeschate both racked up tons of their own to earn a five-wicket success for the visitors.
Westley and his captain shared a fifth-wicket stand of 209 in 31 overs, the former also making 111 for his first List A hundred and the latter scoring 119 from 101 balls with nine fours and six sixes.
David Masters earlier took four wickets for 34 with the ball for Essex.
The Eagles' victory, with 25 balls to spare, moved them joint top of the table with Yorkshire on eight points.
Derbyshire won on the road, beating Northamptonshire by six runs on the Duckworth-Lewis method at the County Ground.
The visitors made an imposing 211 for six in their 32 overs, Wes Durston leading the way with 108 from 94 balls.
They then bowled with skill and patience to keep their opponents below the revised target of 227, with Northamptonshire finishing on 220 for nine.
Only 25 balls were possible at the Ageas Bowl where Hampshire quickly rattled up 42 without loss in a match eventually abandoned due to heavy showers.
Play only got under way in gathering gloom at 7.15pm, and there was time for Michael Carberry to hit a quick-fire 30 not out before it was brought to a halt 15 minutes later.
Each side picked up a point from the match, which was of little help to either.
