DUCK ... DUCK ... GOOSE!

‘To look at Cashman every day, I can’t look at him. He’s a disgrace to the Yankees.’

TAMPA — When Goose Gossage slammed closed the bullpen door at Yankee Stadium from 1978 to 1983, more often than not the game was over. After slamming Brian Cashman on Monday, the Hall of Famer reliever’s relationship with the franchise is likely finished as well.

Not invited to this year’s spring training after admitting to being “disruptive the past two years’’ with comments about how baseball has changed due to analytics, bat flips and the lack of teaching young players the fundamentals, Gossage went up and in on the Yankees’ general manager.

Gossage, whose Hall of Fame bust is adorned with a Yankee cap:

Said Cashman ruined the “honor and privilege’’ of being invited to camp.

Questioned Cashman’s manhood.

Called Cashman a “little weasel’’ who has the Steinbrenner family “tricked.’’

Said the GM is “a disgrace to the Yankees.”

Said new manager Aaron Boone is a “good baseball man but his hands will be tied by Cashman.’’

Stated Cashman has no use for coaches and suggested the GM get a uniform and manage the club.

“If Cashman had any balls, and he doesn’t, he would have an analytical guy manage,” said the 66-yearold Gossage. “Don’t think it hasn’t crossed his mind. But he doesn’t have the balls to do it.”

It’s that kind of vitriol the Yankees were trying to avoid by keeping Gossage away. He has long railed against the showboating that occurs in today’s game and the inability of some relievers to throw more than one inning. He now includes Cashman in the group of people who have made baseball too much about the numbers in his opinion.

In 2016, Gossage ripped into Toronto’s Jose Bautista for bat flips and called him a disgrace. Last spring he said Mariano Rivera shouldn’t be compared to him because Rivera, the all-time leader in saves, worked one inning while Gossage often threw multiple frames.

“It was an honor and a privilege to be invited to camp by Mr. Steinbrenner. It’s an honor and a privilege, but to look at Cashman every day, I can’t look at him. He’s a disgrace to the Yankees,” Gossage said of Cashman, who has been the GM since 1998.

According to Gossage, last spring Cashman told him: “The game has passed you by.’’

Gossage said he usually gets a call from or makes a call to traveling secretary Ben Tuliebitz but didn’t hear anything this year. He said he knows Willie Randolph, Ron Guidry and Stump Merrill have been invited. In addition Reggie Jackson is likely coming and Nick Swisher and Mark Teixeira are on the list of guest instructors.

“You’ll have to ask Cash,” Gossage said when asked what happened.

A message left for Cashman wasn’t immediately returned.

“Everybody knows Cashman and I had differences for the last two years,” Gossage said. “I’m not a big fan of Cashman. I don’t know what I did for him to feel the way he does. I don’t have respect for him. He doesn’t have any respect for older people in baseball.”

The Yankees had spoken to Gossage about his controversial comments in the past, but those conversations had mostly fallen on deaf ears.

Gossage thrived in the chaos that often surrounded the Yankees in the late ’70s and early ’80s when he posted 150 saves in 308 relief appearances. In 518 ²/₃ innings, Gossage struck out 506, allowed 376 hits and went 41-28.

“With George there was always controversy, but you can’t say anything about Cashman,’’ Gossage said. “And the little weasel that he is, he has the Steinbrenner family tricked.’’

Yankees managing general partner Hal Steinbrenner did not want to get drawn into the fray.

“Not going to comment in depth about this, except to say that Goose’s comments were grossly inaccurate. Every single one that I heard,” Steinbrenner said in an email.

Gossage said he likes Boone’s baseball knowledge, but predicted the first-year manager won’t be calling the shots in the dugout and said Cashman has no use for coaches.

“His hands will be tied,’’ Gossage said of Boone, who will open his first Yankee camp Tuesday with a noon press conference ahead of Wednesday’s first pitchers and catchers workout at GMS Field. “Why doesn’t Cashman get a jersey and jump into the dugout if he doesn’t think coaches are necessary?’’
