1. The distance between the pitching mound and home plate is 46 feet. The distance between bases is 60 feet. This is 14 and 30 feet, respectively, shorter than a Major League Baseball diamond.
2. A regulation Little League game is six innings long. Of course, extra innings are possible to break ties. If one team gets ten runs ahead of the other after four innings, a "mercy rule" is invoked, and play ends.
3. A base runner is not allowed to leave the base before the pitched ball crosses home plate.
4. Little League umpires are officially unpaid, although they must go through extensive training.
5. Playing in Little League does not necessarily lead to a career in pro ball. Less than 1% of all Major Leaguers ever played Little League. Ex-Little League pros include Nolan Ryan, Tom Seaver, Carl Yastrzemski, Mark McGwire and George Brett.
6. Danny DeVito was not small for his age when he played Little League. Other famous Little Leaguers include Tom Selleck, Bruce Springsteen, Kevin Costner, Huey Lewis, Dave Barry, Bill Bradley and George W. Bush.
7. The country that has won the most World Series is the US (27 championships), followed by Taiwan (17 wins). In 1997, Taiwan withdrew from Little League entirely because it disagreed with Little League recruitment rules. Non-US teams have been world champions 30 times.
8. An umpire can officiate only once in his lifetime at the World Series.
9. Because of its size, California is the only state divided into two halves, Northern and Southern, for the purposes of state tournament play. On the other hand, North Dakota and South Dakota are combined at the State level.
