In baseball, a player earns a Triple Crown when he leads a league in three specific statistical categories in the same season. The term "Triple Crown" generally refers to the batting achievement of leading a league in batting average, home runs, and runs batted in (RBI) over the same season.[1][2] The term "Pitching Triple Crown" refers to the pitching achievement of leading a league in wins, strikeouts, and earned run average (ERA).
The term "Triple Crown" is typically used when a player leads one league, such as the American League (AL) or the National League (NL), in the specified categories. A tie for a lead in any category, such as home runs, is sufficient to be considered the leader in that category. A "Major League Triple Crown" may be said to occur when a player leads all of Major League Baseball in all three categories.
