Drafted twenty-ninth overall in the 1986 NHL Entry Draft by the Winnipeg Jets, Numminen moved to North America in 1988 to play for the Jets. He moved with the team as it became the Phoenix Coyotes before the 1996–97 season. He played in the NHL All-Star Game in both 1999 and 2000. After fifteen seasons playing for the Winnipeg/Phoenix organization, Numminen was traded to the Dallas Stars in July, 2003, for Mike Sillinger.
