So, the Toronto Blue Jays have signed a Canadian catcher to a five year contract worth about eleventy billion dollars. His name is Russell Martin and he does not usually have a moustache. He is pretty good at baseball, but I think they signed him because they thought it would be easier to just sign a Canadian catcher rather than spend years trying to convert one.
Let me explain. They used to have a catcher named Ernie Whitt. Ernie Whitt definitely had a moustache. He may have, in fact, been born with one. By 1989, he was also the last player to play for the Blue Jays that started when they first took flight (see what I did there?) in 1977.
An internet search leaves things a bit murky as to whether Whitt actually ever became a citizen, but the Blue Jays fought the good fight for years, and eventually Whitt was inducted into the Canadian Baseball Hall of Fame in 2009. Citizenship or not, mission accomplished.
Also, moustache accomplished.
