DETROIT — At a steamy Comerica Park, definitely a stadium and possibly weather conditions that won’t factor into the Yankees’ postseason, Aaron Boone offered his vision of Domingo German’s October.

“I view Domingo playing a really big role for us in the postseason, hopefully,” the Yankees’ manager said Tuesday. “I could see it being a lot of different things. I could see him absolutely starting and being that guy for us. I could see him coming into a game in a huge spot and picking up innings both short and [long].

“Nothing has been defined yet there, and it’s something that will probably remain fluid until we’re finished playing.”

Yet one could argue that a term already exists for German’s role, courtesy of the 2018 Brewers:

The right-hander, like virtually everyone else on the Yankees’ pitching staff, will be an out-getter.

The key to this plan? They’ll need the guys who actually get outs.

The Yankees opened this midweek Midwest series with a ghastly, 12-11 loss to the worst-in-baseball Tigers, yet it came with a silver lining of sorts: The Yankees used eight pitchers in this bullpenning effort, and only two — Adam Ottavino and Zack Britton — will optimally be on their postseason roster. Boone managed this game, justifiably, like a not-must-win, not starting several regulars.

The closer we get to these playoffs, the more it appears the Yankees’ best path to overcoming the Astros, a club relying on a powerful starting rotation, will be a strain of bullpenning. They’ll launch a test run of sorts on Wednesday when they start CC Sabathia and relieve him with German, whose past 22 appearances have been starts.

Yankees pitching coach Larry Rothschild, hesitant to commit to a game plan, said, “It’s hard to tell right now. We’ll see who we’ve got back and how it all fits together.”

Nevertheless, Rothschild acknowledged he followed the Brewers’ unconventional path to NLCS Game 7 last year. It was Milwaukee manager Craig Counsell, close enough to his Yankees counterpart that Boone reached out to him for advice when interviewing for the Yankees’ managerial opening in November 2017, who popularized the term “out-getters” as his club routinely went early and often to its bullpen. Of the Brewers’ 10 postseason games, their starting pitcher qualified for the win (by recording at least five innings) only three times. In none of those three contests did their starter last as many as six innings.

I don’t think the Yankees want to go quite to that extreme. With the way James Paxton, in particular, has pitched lately, you’d be quite open to him going six or seven innings if he’s cruising. Yet the principle stays the same: Pull rather than push.

Imagine games being started by Paxton, Masahiro Tanaka, J.A. Happ, Luis Severino and maybe even German or Chad Green if the Yankees see an optimal matchup. Then picture a second wave, perhaps occupied by some of these same guys, in the third or fourth inning.

Your other six pitchers, assuming everyone’s good health, would be Dellin Betances (like Severino, still working his way back after missing the entire year), Britton, Aroldis Chapman, Tommy Kahnle (who has missed a few days with right wrist tendinitis and hopes to be available Wednesday), Ottavino and Sabathia.

You’d trust each member of this dandy dozen somewhat in a big spot. If this formation underwhelms you from the standpoint of, “I doubt any of these guys will join Don Larsen by tossing a Fall Classic perfect game,” its breadth stands out when you remember how the Yankees won their last two titles: In 2009, they relied upon a three-man starting rotation featuring Sabathia, A.J. Burnett and Andy Pettitte. And in 2000, they trusted, essentially, six pitchers: Starters Roger Clemens, Pettitte and Orlando Hernandez and relievers Jeff Nelson, Mike Stanton and Mariano Rivera.

No 2000 or 2009 foe arguably compares to these Astros. These Yankees can’t get by with a trusted core. They’ll require an entire village of out-getters, each doing his part, to upset both conventional wisdom and a superior opponent.
