Chris Mason made his NHL debut in the 1998-99 Season, appearing in three Games, and it took another two years before he appeared in another NHL Game, a single one in the 2000-01 campaign.  Mason signed with Florida in 2002 but never made it to their main roster and would be claimed back a year later, and he would finally see some serious action in the biggest hockey league in the world.

Mason was his backup in 2003-04 and 2005-06 (2004-05 was a lockout), but he was in between the pipes for 40 Games in 2006-07, posting a 2.38 GAA and 9.25 Save Percentage.  The following year, those numbers were lower, but he was elevated to the top Goalie in Nashville, appearing in 51 Games.  Mason was traded to St. Louis at season's end, but he returned as a Free Agent for one final season in 2012-13, appearing in 11 Games before retiring.

He had a record of 59-50-13 with the Predators with a 2.68 GAA.
