de Grooth - quickfire knock at the top of the order.
Holland added to their 172-run win in the first ODI with an eight wicket triumph over Bermuda in the second ODI in Rotterdam on Monday.
The loss hands the tourists a 2-0 series whitewash.
Winning the toss and opting to bowl first, the Dutch bowled the hapless visitors out for just 115 in less than 44 overs.
Lionel Cann (21) was the only bloke who managed to provide a bit of fight in the Bermudan batting order, with Maurits Jonkman finishing (three for 22) the pick of Holland's bowlers.
The hosts took 19.3 overs to knock off the 116 required for victory, losing just two wickets in the process.
Alexei Kervezee finished unbeaten on 49 while Tom de Grooth pitched in with a whirlwind 21-ball 31.
