Today I learned that the team currently known as the Boston Red Sox was originally known at the Boston Americans. From the 1901-1907 seasons they were the Americans and from 1908 to today they have been the Red Sox. Oh, and some dude named Cy Young was their best player for most of those years. You may have heard of him.
