In the earliest days of organized baseball, Brooklyn teams dominated the new game. The second recorded game of baseball was played near what is now Fort Greene Park on October 24, 1845. Brooklyn's Excelsiors, Atlantics and Eckfords were the leading teams from the mid-1850s through the Civil War, and there were dozens of local teams with neighborhood league play, such as at Mapleton Oval. During this "Brooklyn era", baseball evolved into the modern game: the first fastball, first changeup, first batting average, first triple play, first pro baseball player, first enclosed ballpark, first scorecard, first known African-American team, first black championship game, first road trip, first gambling scandal, and first eight pennant winners were all in or from Brooklyn.
