45、 the game was a native of Columbia. The rosters of both teams were awash with Hispanic names, as is Miami, which now claims the World Championship is a game that may be losing popularity in America, but has gained it in much of the rest of the world. Baseball in America has taken on a strong Hispani

46、c flavor, with a dash of Japanese added for seasoning. Soccer, which many countries just call football, is the most widely enjoyed sport in the world.

47、ed States has largely been an import, played by South Americans and Europeans. Now, American citizens in large numbers are finally taking up the most popular game in the world.
