Home run jokaldi berean bateatzaileak pilota lau baseak zeharkatu eta lasterketa bat egitea lortzeko moduan jotzen duenean gertatzen da, defentsaren out edo akatsik gabe.
In baseball, a hit in which the batter is able to circle all the bases, ending at home plate and scoring a run himself (along with a run scored by each runner who was already on base), with no errors by the defensive team on the play which result in the batter advancing for extra bases.
