2014 MLB Baseball Playoffs. Baseball Playoffs are upon us! The World Series has only been canceled twice! Since 1903, only two years have gone by without a World Series. Interestingly enough, neither of these years came during World War II, during which the best players from many teams fought overseas. Most recently, 1994, a players’ strike thwarted the championship. But in 1904, it was a National League owner who disappointed fans by preventing the annual event.
