Base runner

The base runner in baseball refers to a member of the offense team whose job it is to clear all four bases to be able to score a run. Once a player has hit first base, they are considered a base runner as they are now on base. To score a run, the base runner needs to pass the first base, second base, third base and home plate. When passing these bases, the base runner needs to make contact with them.

A batter can become a base runner when one of the following happens:

  • They hit a ball into fair territory that isn’t putout.
  • The defense team commits an error, which allows the batter to proceed.
  • They are hit by a pitch.
  • They are awarded a base on balls.
  • The third strike goes uncaught.
  • A fielder interferes with the batter.

A base runner stops being a runner when one of the following occurs:

  • They score a run.
  • They are put out in any way.

A teammate is put out for the third time in one inning.
