hits.
home runs.
the number of runs scored by a player. A run is scored by an offensive player who advances from batter to runner and touches first, second, third and home base in that order without being put out.
Runs Batted In: A hitter earns a run batted in when he drives in a run via a hit, walk, sacrifice (bunt or fly) fielder's choice, hit-batsman or on an error (when the official scorer rules that the run would have scored anyway).
A “walk” (or “base on balls”) is an award of first base granted to a batter who receives four pitches outside the strike zone.
