Robinson Cano proudly posted that on Twitter today he became a citizen of the United States of America. Such an act used to have a lot more significance in this country than it does now. But for this old-timey baseball writer, such an act is a very cool thing. Way to go, Cano. Welcome to citizenship. If you click the link for his tweet, you will also see a picture of the proud ballplayer holding a flag and his certificate. Nice.
