He debuted for the national team in the 2005 European Championship with a 6.43 ERA and pitched one inning in the 2005 Baseball World Cup, allowing one hit, striking out one and allowing no runs as the Dutch squad finished 4th, their highest to that point.

In the 2006 Haarlem Baseball Week, he allowed one run in three innings of work. He then wrapped up the year with the 2006 Intercontinental Cup, allowing one run in 4 2/3 IP and notching a save for the Silver Medal winners.
Nick moved back to Amsterdam and bounced between relief and starting in 2007. He was 2-3 with 3 saves and a 2.29 ERA for the Pirates and helped them to their first playoff appearance in a long time. He was 2-0 with a 3.65 ERA in the playoffs but Amsterdam lost to Kinheim, the eventual champions.
