No other sport arguably has as rich a history as Major League Baseball. One reason is because of its 120-plus years of national popularity. Another comes from the ballparks, some of which are so old that they are in the U.S. National Register of Historic Places. With that in mind, here are MLB's 10 oldest ballparks.
NOTE: While Tropicana Field opened in 1990, it did not house the Tampa Bay Rays until 1998 so I do not have it on this list.
