SCOTTSDALE, Ariz. — The Yankees are treating their end-of-season organizational meetings and any tangible changes that might come from them like “Fight Club.”

The first rule is that they can’t tell you about it.

Hal Steinbrenner and Brian Cashman on Tuesday both insisted that the Yankees had productive meetings in Tampa last month in an attempt to dive deep into why the team struggled through an 82-80 season.

But when pressed for specifics about what they took away from those meetings or how they will impact the club moving forward, both declined to offer much in the way of details.

Steinbrenner still pledged “big changes,” but the only ones he provided publicly were hiring a new hitting coach — James Rowson is expected to be the choice after Sean Casey left for family reasons — and bringing on Zelus Analytics for a year-long evaluation of the Yankees’ own processes.

“There are changes that might be significant as far as we’re concerned or the players are concerned but might not seem too significant to you guys [reporters] or the fans,” Steinbrenner said on a Zoom press conference, his first comments since the season ended. “But it’s all an effort to right this ship and be operating in the most efficient way and the most successful way that we can.”

Cashman also declined to go into specifics about the meetings, which lasted three days.

“I’m not going to tell you what else happened in that meeting,” Cashman said. “You want me to put you in that room and I’m not doing that. We had organizational meetings. They did get heated. We had a lot of discussions. Some stuff we agreed on. Some stuff we disagreed on. We unpacked a lot of different stuff. Some of it, we’re making adjustments. Some of it, we actually recommitted to.”

One of the main topics of conversation was expected to be the Yankees’ use of analytics, especially after Aaron Judge said on the final day of the regular season that they may be devaluing the wrong numbers.

Cashman said Tuesday that he asked Judge about which numbers he was referring to and the answer was RBIs and batting average.

Steinbrenner also went to bat for the Yankees’ analytics department, specifically in terms of how they guide manager Aaron Boone’s decision making during the course of a game.

“Look, analytics has taken a lot of heat — not justified, in my opinion,” Steinbrenner said. “But I think one of the misconceptions that’s out there, because I hear it from a lot of people, is that Boone makes every decision in the dugout during a game based on analytics. That’s just not true. Analytics gives Boone and the coaches a lot of information; so do the pro scouts. It’s up to Boone during the game, when he puts the lineup together and then everything after, what he wants to do with all that information.

“Honestly, if you ask the analysts, they’ll probably say too many times Boone makes a decision during the game that’s based on his experience, what he’s seeing, his intuition. Whether that’s accurate or not — I can assure you we don’t have an analyst standing behind Boone in the dugout telling him, ‘You need to pinch hit here, you need to get this pitcher out of here, you need to steal a base.’ ”

As for the Yankees’ partnership with Zelus Analytics, Steinbrenner and Cashman revealed that assistant GM Mike Fishman, who runs the Yankees’ analytics department, is the one who suggested bringing them on.

The Yankees will get a look at the processes Zelus — founded by a pair of former Dodgers executives — uses to analyze data and make decisions and compare it to their own in-house operations.

“If we see that in some of their algorithms, they do something a little different, we’ll ask why and we’ll make a determination, is that a better way or is our stuff better than their stuff?” Cashman said. “That’s really all that’s about.”
