Among the reasons the Yankees’ bullpen was taxed so much during the playoffs was the absence of Domingo German, who spent the postseason on administrative leave following allegations of domestic abuse last month.

GM Brian Cashman said Thursday he was not allowed to comment on the ongoing investigation, noting the team isn’t involved in it.

But he did talk about what the absence of both German and Dellin Betances (Achilles) meant to the team.

“We took a big hit when we lost one of the best starters in American League in late September [and] that had a cascade effect,’’ Cashman said of German. “The players that we were actually anticipating and expecting to be a part of the October process disappeared on us in the last two weeks of the season.’’
