Yankees pitcher Domingo German “grew belligerent” in the clubhouse Tuesday before seeking treatment for alcohol abuse, according to a new report.

German, who was placed on the restricted list Wednesday by the Yankees after voluntarily submitting to inpatient treatment, “grew belligerent while in the clubhouse at Yankee Stadium,” according to SNY.

The report clarified the pitcher was not involved in an “altercation” with teammates.

However, the report said, “Witnesses determined that German was under the influence of alcohol and did not appear in control of his emotions.”

German was suspended for 81 games between 2019 and 2020 for an alleged domestic violence incident.

German is not under investigation by MLB for domestic violence, according to SNY, and this was a matter the Yankees handled internally.

Yankees general manager Brian Cashman told reporters on Wednesday that he expects German — who pitched a perfect game in late June — to miss the rest of the season.

“It’s a very serious issue that affects way too many people, unfortunately,” Cashman said before the Yankees’ win over the Rays. 

“Hopefully the steps that are being taken today will really benefit him for the remaining part of his life, because it’s a very serious problem that you need to address head-on. These treatment places are significant steps, hopefully towards helping him get the tools to solve it.”

Cashman also said the alcohol issue was completely separate from German getting scratched from his start with an armpit injury.

Star Yankees pitcher Gerrit Cole offered his support for German.

“It’s been tough,” Cole said. “It just affects you as a human being. You care about your teammates and you care about your teammates’ families. It’s a sad situation and you want the best for Domingo.”

At 56-52, the Yankees are three-and-a-half games behind the Blue Jays for the final AL Wild Card spot.
