Hey, Dellin Betances . . . can you get one more out?

TAMPA, Fla. — It was the first “oops” moment of Aaron Boone’s managerial career.

After Dellin Betances gave up a run in the fourth inning, he figured his day was done. The 6-8 righthander retreated to the clubhouse and began undressing.

Turns out he wasn’t finished, though. Because of what Boone called “a miscommunication” — no one called down to the bullpen to get Adam Warren up — Betances had to go out for the fifth inning, too. A messenger was sent into the clubhouse to retrieve him.

“They’re like, ‘Can you please go back out? Warren’s not ready,’ ” Betances said with a smile. “I’m like, ‘All right. Let me put my stuff back on. Let’s go.’ At that point, I was already done but it’s, whatever. I felt good. It was kind of awkward going back out, but we got through it.”

After Betances allowed a leadoff single to Luis Guillorme in the fifth, pitching coach Larry Rothschild went out to remove him. By then, Warren was ready.

Boone called the circumstance “pretty aberrational,” in large part because, with the game on the YES Network, he was about to put on his headset for an in-game interview at a time when he usually would have been tending to the bullpen.

“It was an inning where I was on with the booth upstairs and just the rhythm of spring training,” Boone said. “I don’t see that being a situation that would really happen in a real game. I just think the timing of getting all the relievers in got a little out of whack.”

Sigh of relief

Tyler Wade, by all accounts the front-runner to win the starting job at second, left the game in the sixth after making a diving attempt to stop Jose Reyes’ ground shot up the middle. Wade landed awkwardly on his left wrist and was pulled from the game, though he later said he argued with Boone and trainer Steve Donohue to leave him in.

“I’m fine,” Wade said. “Scary more than anything else. I’m glad I’m OK.”

Wade, who has hit .292 with a .357 on-base percentage in 11 games and played standout defense, said he expects to be back in the lineup Monday.

D-Rob doesn’t miss a beat

In his exhibition debut, David Robertson was brought in to replace starter Luis Cessa with the bases loaded and one out in the second. Robertson — nicknamed “Houdini’’ — escaped, striking out Amed Rosario and Juan Lagares swinging at curveballs.

“Definitely a familiar setting,” said Robertson, who had been sidelined by a bout with food poisoning. “I tried to do the same thing as I’ve done in the past, which is make a couple of quality pitches. Lucky enough to get two strikeouts there and get out of it.”

Robertson, reacquired from the White Sox before the trade deadline last July, said that even in spring training, getting out of that kind of jam felt good.

“These guys want to get their hacks in, they want to hit the ball hard,” he said. “It’s still a spring training game, but these guys are out there competing.”

Mowing ’em down

Aroldis Chapman followed Robertson to the mound and needed only 10 pitches to get through a perfect third, striking out Brandon Nimmo on a changeup and Wilmer Flores on a fastball. With those two relievers, plus Betances, Warren and Chad Green, the Yankees’ bullpen figures to be among the league leaders in strikeouts again.

“There’s a lot of weapons out there in the bullpen this year,” Robertson said. “A lot of power arms, a lot of guys with experience. We’re going to be a stronger team because of the bullpen.”
