MLS Cup Winners

The Seattle Sounders and Toronto FC meet on Saturday, December 10, at TFC's BMO Field to determine the 21st Major League Soccer champion. The two high-powered teams are vying for their first title, attempting to emulated what the Portland Timbers did after beating Columbus Crew SC 2-1 after a wild final last year. The 2015 MLS Cup put a cap on two decades of league play, with Columbus coming up short as it gunned for its second title (its other coming in 2008), while Portland captured its first league championship, five years into its MLS existence. The Timbers join 19 other MLS champions, and either Seattle or TFC will be added to the esteemed group.

Here are the league's kings, year by year.
