There are some rules in the current game of baseball that are etched in stone. For every homerun hit, you travel around four bases. Four balls equals a walk, three strikes equals an out, and three outs means that the other team must come up to bat. There are nine innings in a regular game that is not shortened by rain or lengthened by extra innings.
Other baseball rules, though not necessarily permanent, have helped shaped the game to what it is today. A five-inning game is an official one in tomorrow’s boxscores. A batter can run to first on a swinging third strike if there was a wild pitch or passed ball on that third strike (remember A.J. Pierzynski in last year’s playoffs?).
