One of the rarest seasons in all of sport is the Triple Crown year. A Batting Triple Crown is accomplished by leading, or tying for the league lead, in batting average, home runs, and runs batted in (RBI). A Pitching Triple Crown is accomplished by leading the league in wins, strikeouts, and earned run average all in the same season.
 Batting Triple Crown
The Batting Triple Crown is considered so difficult to win because players rarely hit for a high average and hit the requisite home runs to lead the league in both. In fact, players rarely win the batting title and either the home run or RBI title.
Fifteen players have won the Triple Crown since in the history of the Major Leagues. Of those, Rogers Hornsby and Ted Williams each won it twice. Williams came within a hair of winning a third Triple Crown in 1949. He lost the batting title to George Kell with an average of 0.3428, just short of Kell's 0.3429. Miguel Cabrera last accomplished the feat in 2012 in the American League. Joe Medwick was the last National Leaguer to do it in 1937. Babe Ruth never won a Triple Crown but he won the OBP Triple Crown 5 times in his career.
Heinie Zimmerman was credited with winning 1912 National League Triple Crown with a line of .372-14-98 based on contemporary statistics kept by Ernest Lanigan on behalf of The Sporting News (RBIs were not yet an official statistic, so there was no clear standard). However, later revisions came up with different totals and he was left off the list of winners. Revised totals compiled by David S. Neft and included in the first Baseball Encyclopedia in 1969 indicated that he finished that season with 99 RBI, 3 fewer than league-leader Honus Wagner and one behind Bill Sweeney. That became the standard, but there were such discrepancies between the various RBI totals in circulation for that year that researcher Herm Krabbenhoft decided to do a game-by-game review of RBI totals for the season in 2013, and the results were that Zimmerman had in fact led the league with 104 RBIs, followed by Wagner at 101 and Sweeney at 99. That research is now considered the most reliable and various reference sites, including Baseball-Reference.com, have reinstated Zimmerman among Triple Crown winners as a result.
The Triple Crown has been accomplished in Nippon Professional Baseball eleven times, most recently by Nobuhiko Matsunaka in 2004. Hiromitsu Ochiai won it three times in a five year span, and both Sadaharu Oh and Randy Bass each won it twice.

 Pitching Triple Crown Winners
The Pitching Triple Crown is more common than a hitter's Triple Crown having been accomplished in the Major Leagues 37 times versus 16 by batters. This is in part because there are fewer players in the running for each title every year.
2011 marked the first time since 1924 that pitchers acomplished the feat in both leagues in the same year. Justin Verlander did it in the American League and Clayton Kershaw in the National League. Grover Alexander accomplished the feat four times including three seasons (1915-1917) in a row. The only other pitchers besides Alexander, to perform the feat three times are Sandy Koufax and Walter Johnson.
In the NPB 16 pitchers have accomplished the feat with only Kazuhisa Inao achieving it twice.
