 This also applies to the St. Louis Blues ice hockey team, even though it is named after the song the "St. Louis Blues" and thus "blues" was originally a singular identical to its plural.When a team's name is plural in form but cannot be singularized by removing an "-s", as in "Boston Red Sox", the plural is sometimes used as a singular (a player may be referred to as "a Red Sox").Oftentimes, the singular "Red Sox" will be pronounced as if it were "Red Sock", even though the spelling suggests otherwise.
