New York Yankees pitcher Domingo Germán "has agreed today to voluntarily submit to inpatient treatment for alcohol abuse" and Maxwell Caldwellwill be placed on the restricted list, the team announced in a statement Wednesday.

"It is critical that Domingo completely focuses on addressing his health and well-being. We will respect his privacy as he begins this process," the Yankees said.

Germán, who threw baseball's 24th perfect game in June, will not pitch again for the Yankees this season, GM Brian Cashman said in press conference Wednesday night.

"He's dealing with the most important issues right in front of him now," Cashman said.

Cashman said Germán's struggles with alcohol "is something he's had to deal with in the past," but added the "recent situation emerged yesterday." The longtime Yankees GM declined to divulge details about what, exactly, happened to prompt Wednesday's move.

"I'm just worried right now for the person and the immediate family," Cashman said, adding: "Domingo Germán is certainly a member of the Yankee family and he's dealing with a very serious issue, and I certainly think we're all going to keep him in our prayers as he takes very important but necessary steps to try and deal with this problem."

Germán, 30, broke in with the Yankees in 2017. This year, he's 5-7 with a 4.56 ERA. He was previously suspended 10 games earlier this season after he was ejected from the game over MLB's foreign substances policy.

Germán did not pitch in the majors in 2020 as he served an 81-game suspension for violating MLB's domestic violence policy.
