The Yankees outfielder is at 61 home runs and counting, but he’s also looking for another exceptionally rare achievement: The Triple Crown. Just one Triple Crown has been won since Carl Yastrzemski with the Red Sox in 1967; Miguel Cabrera achieved the feat in 2012 with the Tigers.

Judge has flown onto the Triple Crown scene in a year where it looked like the National League might produce a leader in batting average, home runs and runs batted in. Paul Goldschmidt looked like a real threat in St. Louis, but he’s now off Kyle Schwarber’s home run pace.

Judge has two categories — home runs and RBIs — all but locked up. He’s fighting with Luis Arraez of the Twins for the batting title.

Here’s what to know about Judge’s court with history.

What is the Triple Crown?

For those not in the know, the Triple Crown is when a player leads either the American or National League in batting average, home runs and RBIs.

The feat is exceptionally rare, particularly in modern baseball, where contact is often sacrificed in favor of launch angle. 

While the Triple Crown used to be less rare, it is nearly unheard of in today’s game. Cabrera won the Triple Crown in 2012 with a .330 average, 44 home runs, and 139 RBIs. The latter two stats led the major leagues.

Before Cabrera, the most recent player to win the award was Yastrzemski, who batted .326 with 44 home runs and 121 RBIs in 1967.

How close is Aaron Judge to a Triple Crown?

Judge has the home run and RBI races all but locked up, as he has an insurmountable lead over Mike Trout in the home run category and a sizable one over Jose Ramirez in RBIs.

Where the race is tight is in batting average. He trails the Twins’ Luis Arraez by four points through games of Oct. 2. It’s shocking that Judge is in this position, given that his average was at .282 as recently as July. Judge’s torrid pace since has him back in position to reach yet another peak in what is arguably the best contract year in MLB history.

Judge’s biggest threat now is Arraez after Bogaerts suffered his version of a slump.

Who has won the Triple Crown?

Since MLB added Negro League records to the MLB record books, the list of Triple Crown winners has expanded, but the feat is still exceptionally rare.

There have been 18 Triple Crown winners in MLB history, with Rogers Hornsby and Ted Williams being the only players to have done it twice.

Of those on the list, only Zimmerman, O’Neill and Hines are not in the Hall of Fame. O’Neill is enshrined in the Canadian Baseball Hall of Fame. Cabrera, of course, is not a Hall of Famer but has a one-way ticket to Cooperstown upon his retirement.
