[5] van Mil signed a seven-year deal as a non-drafted free agent on 7 July 2005, with the Minnesota Twins.

He suffered a partially torn ulnar collateral ligament in his right arm while preparing for participation in the 2008 Summer Olympics and missed the first seven weeks of the 2009 season while rehabilitating.

[9] van Mil began his 2009 season in late May with the Fort Myers Miracle, playing in the Class A-Advanced Florida State League.

He was designated for assignment by the Twins to open a roster spot for newly acquired Brian Fuentes on 27 August 2010.

[8] van Mil signed a one-year deal with the Rakuten Golden Eagles of Nippon Professional Baseball in early 2014.

[8] In March 2015, van Mil agreed to a one-year contract with Curaçao Neptunus in the Dutch Honkbal Hoofdklasse.

[14] van Mil pitched for the Twins' Triple-A affiliate, the Rochester Red Wings, debuting on 2 September 2015 with 2 scoreless innings in relief in his first action stateside since 2013.

[20] He had two more scoreless appearances for the Red Wings in 2015. van Mil started the 2016 season in Rochester, but his performance was notably worse.

[26] In what NBC reported was thought to be the tallest batter-pitcher matchup in baseball history, the 7-foot-1-inch (2.16 m) van Mil walked 6-foot-8-inch (2.03 m) Nate Freiman of Israel in a game on 9 March 2017.

[2] His height provided an advantage, because his release point when pitching was closer to hitters, giving them less time to react.

[32] van Mil died on 28 July 2019, with a statement from the Royal Netherlands Baseball and Softball Federation attributing his death to a fatal accident.
