Netherlands 204 for 6 beat Derbyshire 191 for 9 by 13 runs
Netherlands claimed a second county victim in successive days as Derbyshire were beaten by 13 runs in Clydesdale Bank 40 Group A at Derby.
Skipper Peter Borren followed his unbeaten 56 with bowling figures of 3 for 29, stifling the Falcons' late charge after a stand of 117 between fourth-wicket pair Wes Durston and Wayne Madsen threatened to deny the Dutch a repeat of their thrilling victory over Yorkshire at Headingley.
A one-day best of 74 from Wesley Barresi earlier lifted the Netherlands to 204 for 6 as they doubled the number of wins they managed in the competition last season.
The Dutch hit early trouble in their innings as Derbyshire's tactic of opening the bowling with left-arm spinner Chesney Hughes paid off when Eric Szwarczynski charged down the wicket and was bowled with only one run on the scoreboard in the second over.
Tom Cooper was caught at mid-off trying to hit Steffan Jones over the top and when Michael Swart was caught behind off Mark Turner, the score was 47 for 3 after 15 overs.
But Barresi and Tom de Grooth batted sensibly to stabilise the innings with a stand of 76 in 15 overs before de Grooth aimed a wild cut at a Ross Whiteley ball and was caught at third man for 39, leaving Holland 123 for 4.
Borren made sure the momentum was not lost and was the senior partner as 45 were added in the next six overs.
Even when Barresi's innings ended with a fine catch by Durston at mid-on and Shane Mott quickly followed in the next over, Borren moved to his half-century off 34 balls with one six and six fours as he helped his side put on 15 runs in the final over.
Left-arm seamer Mott caused havoc at the beginning of the Derbyshire reply, having Dan Redfern caught down the leg side with his fourth ball.
Hughes and Greg Smith were soon also back in the pavilion, leaving their side 19 for 3 in the ninth over, as the Australian's first six-over spell brought him 3 for 16.
Durston and Madsen began the process of digging the Falcons out of their hole and, with 75 more needed in the last 10 overs, the home side were slight favourites.
But Durston was caught at long on for 64 at 136 for 4 in the 31st over and the Falcons' innings lost its way, even though Madsen moved on to 75 and Jones threatened a last-gasp recovery by hitting 18 off the penultimate over.
