Shortly after getting walked-off by the Diamondbacks on Saturday night, the Yankees acknowledged their reality.

“Mathematically, [it’s] probably pretty tough, but you never know,” Cody Bellinger said of winning the American League East.

Unable to bounce back with an 8-4 loss in Sunday’s series finale against Arizona, the second-place Yankees are now six games back of the division-leading Rays with seven games left in the regular season. The rivals will play four of those games against each other at Yankee Stadium this week, starting with a doubleheader on Tuesday.

Aaron Boone acknowledged that his team will probably have to sweep the Rays just for a crack at the division crown, as FanGraphs gave the Yankees a measly 2.7% chance of winning the AL East before Sunday’s game.

“There’s still a chance,” Cam Schlittler said, “but we gotta play our asses off a little bit.”

While the Yankees still technically have a shot to defy the odds, the far likelier scenario is that their postseason begins on Sept. 29 at home against Boston in the Wild Card round for the second straight year.

With that in mind, let’s try to predict what the club’s roster could look like for that series.

Hitters (15): Ben Rice, Heliot Ramos, Spencer Jones, Trent Grisham, Cody Bellinger, Ryan McMahon, George Lombard Jr., Paul Goldschmidt, Luis García Jr., Jazz Chisholm Jr., José Caballero, Austin Wells, Ali Sánchez, Anthony Volpe, Amed Rosario

With the Yankees providing minimal info on Aaron Judge’s calf strain, it can’t be assumed he’ll be available.

Jazz Chisholm Jr. could return from a sprained thumb as soon as Tuesday. Meanwhile, Trent Grisham is still in play as a playoff option as he recovers from a hamstring strain, but Boone said that activating him before the end of the regular season is “complicated,” partly due to roster logistics.

With Max Schuemann presumably the corresponding move for Chisholm, the Yankees would have to option someone else if they activated Grisham before the playoffs. That someone wouldn’t be able to be recalled for 10 days barring a new injury; it seems like Jasson Domínguez is being protected from that window in case he’s needed for the Wild Card roster.

Grisham has been doing baseball activities and is “pretty deep into his running progression,” Boone said. If he is on the Wild Card roster, the Yankees will have an interesting decision to make between him and Spencer Jones in center field.

Third base could also be a conundrum, as Ryan McMahon and José Caballero don’t offer much offensively, and Amed Rosario is a poor defender. He’s only on the roster as an option against lefties, even though he hasn’t been great against them.

Another idea would be to use Volpe, who has been playing second, at third against lefties since he played a few games there in the minors this season. However, he doesn’t have a strong arm, and he hasn’t been working at third base since being recalled. Volpe said that the Yankees have not talked to him about manning the hot corner before the regular season ends.

“We’ll see,” Boone said. “First things first, getting Jazz back, and then we’ll figure out as the week unfolds how I want to play it.”

Volpe can also play second over Chisholm against lefties.

Pitchers (11): Cam Schlittler, Gerrit Cole, Max Fried, Will Warren, David Bednar, Brent Headrick, Paul Blackburn, Clarke Schmidt, John Schreiber, Tim Hill, Ryan Weathers

As things stand, Carlos Rodón, Max Fried, Gerrit Cole and Cam Schlittler are scheduled to pitch against the Rays, in that order. That would give Cole, who has struggled to get swing-and-miss, an extra day of rest if he were to start Game 1 of the Wild Card round. Schlittler, the AL Cy Young frontrunner, would be on regular rest if tabbed for Game 1.

Because the Wild Card round is a best-of-three series, Rodón isn’t needed, especially with Will Warren expected to work out of the bullpen and able to provide length.

Warren, slated to make one more start this season after struggling on Sunday, is one of a few converted starters who could impact the Bombers’ bullpen this postseason. Clarke Schmidt and Ryan Weathers are the others. Schmidt, being cautious in his return from Tommy John surgery, couldn’t come into Sunday’s game due to some bicep cramping, while Weathers isn’t expected to return from a flexor strain before the regular season ends.

Still, neither Boone nor pitching coach Matt Blake ruled out the idea of Weathers’ first game back coming in the playoffs.

“I don’t know if ‘comfortable’ is [the right word],” Blake said, “but it might be the course of action where he’s the best option even though he hasn’t pitched in the last three or four weeks.”

As for the relievers that the Yankees have leaned on all season, David Bednar, Paul Blackburn and Brent Headrick headline the group. All have been used heavily, especially Headrick.

The lefty allowed a grand slam to Nolan Arenado and saw his fastball velocity down an average of 1.3 mph during his major league-leading 79th appearance on Sunday, but he insisted that he feels fine physically. Boone also downplayed concerns over Headrick’s ongoing velocity fluctuations, though he did say that he hopes to get him and other relievers “in a good spot” with some rest ahead of the playoffs.

That said, the Yankees still haven’t been eliminated from the AL East race. They’ll keep trying to take the division from the Rays until they are.

“We’re going to show up Tuesday,” Boone said, “and try and kick their butt.”
