National League Triple Crown

In Major League Baseball, a player earns the 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. 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.

The term "Triple Crown" generally refers to the batting achievement. A batter who completes a season leading a league in batting average, home runs, and runs batted in (RBI) may be said to have won the "Triple Crown". As the term, unless modified, connotes the batting achievement, it may not be necessary to refer to this as the "batting" Triple Crown.

The Triple Crown reflects the ability of a batter to excel in three important ways: to hit safely a high percentage of the time (batting average); to hit the ball long distances (home runs); and to produce when runners are on base, driving them home to score (RBI). It is an uncommon feat to lead all batters in each of these categories. It has been accomplished 17 times, most recently in 2012, by Miguel Cabrera. Cabrera's was the first since 1967, when Carl Yastrzemski accomplished the feat.
