In professional baseball, a runner is said to be in scoring position (sometimes abbreviated RISP) if he is currently on second or third base. This means that if the batter hits a base hit into the outfield, there is a good chance that a reasonably fast runner will be able to run home before the ball is thrown to home plate. Of course, especially slow runners will not be able to make it, and exceptionally good outfielders will be able to throw the ball home in time.
Due to the added pressure associated with having runners in scoring position, the Elias Sports Bureau provides batting average statistics for various situations, including runners in scoring position. It is also considered bad for a team to end an inning (get the third out) with runners left in scoring position. This team statistic is abbreviated RLISP or LISP.
