- Step 1: Score an RBI for balls put in play Score an RBI for the batter when a runner scores as the result of a safe hit, a sacrifice bunt, a sacrifice fly, an infield out, or a fielder's choice out.
- TIP: A home run scores an RBI for the batter because the run scored is a result of the batter's hit.
- Step 2: Score an RBI for a walk Score an RBI for the batter when the bases are full and the batter is awarded first base because of a base on balls, because they are hit by a pitch, or because of interference or obstruction.
- Step 3: Score an RBI on an error Score an RBI for the batter when there is only one out and the fielding team commits an error on a play during which a runner on third base would have scored despite the error.
- Step 4: Don't score an RBI for double plays Don't score an RBI for the batter when a runner scores during a force double play or a reverse-force double play.
- Step 5: Don't score an RBI on an error Don't score an RBI for the batter when a run scores because of an error committed by the fielding team that would've completed a force double play.
- Step 6: Score an RBI on an error Score an RBI for the batter when a fielder holds the ball or throws it to the wrong base if the runner keeps going. If the runner stops and, upon noticing the error, starts running again, the run is scored as a fielder's choice rather than an RBI.
- Step 7: Allow an RBI at the official scorer's discretion Score an RBI for the batter if an error is made on a play but the official scorer determines that the run would've scored regardless of the error.
- Step 8: Don't score an RBI on a balk Don't score an RBI for a run scored as the result of a balk. A balk is called when the pitcher commits any illegal motions during their delivery to home plate. When a balk is called, each runner on base moves up one base, and a runner on third base scores.
- FACT: Baseballs are rubbed with mud from a secret location in New Jersey before being used in big league games.
