Jazz Chisholm, Jr. Shuts Down Aaron Judge’s Personal Hitting Coach

"I don't get it," he replied, seemingly confused by Schenck's post before shutting down what Schenck had likely hoped would turn into a longer interaction—or perhaps even a connection.

Schenck doubled down, urging Chisholm to make changes that would turn him into a "perennial All-Star." Chisholm had already moved on.

It's not the first time Schenck has taken aim at Judge's teammates. Last fall, as Judge tried to carry the Yankees to an American League East crown, Schenck trashed the team’s player development system, except, Judge, of course.

Judge, who continues working with Schenck every two weeks, had to brush off the controversy. He noted that he couldn't control what others post on social media. Yankees manager Aaron Boone also had to address the situation before a game.

Still, Judge's success has given Schenck a platform and the confidence to preach his method based on having broken down former slugger Barry Bond's swing.

Judge has credited Schenck, based in St. Peters, Mo., with helping to "tighten his swing" during the 2016-17 offseason. Schenck has also worked with other Yankees at Judge's sessions. 

Schenck isn't shy about voicing his opinions online. He frequently argues with critics, takes shots at other hitting coaches and engages in disputes with former MLB players.

One of the best arguments came last year in a hilarious, insult-laden exchange with Atlanta Braves Hall of Famer Chipper Jones on X.com. 

Schenck told Jones to try to understand his methods before opening up his "piehole." Jones responded by calling Schenck a "used car salesman."
