Meeuwis debuted with the Twins in 1999 as a teenager but did not return to Hoofdklasse again until 2004, when he became a full-time player. When the Twins were relegated, Meeuwis moved to HCAW.

Balentina was back with the team for the 2007 European Championship but Meeuwis replaced him once more for the 2007 Baseball World Cup. He was 3 for 10 with 2 walks and a double in the World Cup that year, helping fill in when CF Roger Bernadina. He had a key role in the Dutch win over host Taiwan in the quarterfinals.
