Scott Allen can't tell you who's going to win the World Series. But his 2010 self can tell you where the participants' names came from.
St. Louis Cardinals
In 1899, the St. Louis Browns became the St. Louis Perfectos. That season, Willie McHale, a columnist for the St. Louis Republic reportedly heard a woman refer to the team’s red stockings as a “lovely shade of Cardinal.” McHale included the nickname in his column and it was an instant hit among fans. The team officially changed its nickname in 1900.
A second franchise named the Senators left Washington in 1972, this time for Arlington, Texas. Owner Robert Short renamed the team the Rangers after the Texas law enforcement agency that was formed under Stephen F. Austin in the 1820s.
