CINCINNATI — The vibes have shifted around the Yankees so much lately that they can sit Aaron Judge and still finish off a ridiculous road trip in style.

Even without the red-hot Judge on a day when the first pitch was thrown at 11:37 a.m., the Yankees’ offense kept humming and Luis Severino looked strong in an encouraging season debut on the way to a 4-1 win over the Red on Sunday at Great American Ball Park.

The three-game sweep of the Reds (19-27) capped off a seven-game trip that featured a heavy dose of drama and absurdity — most of it coming against the Blue Jays with some more sprinkled in here — but also six wins for the surging Yankees (29-20), who return home having won 11 of their last 14 games.

“I think we learned a lot about ourselves on this road trip,” said Harrison Bader, who gave the Yankees the lead with a two-run homer in the fifth inning. “If we didn’t already know it prior to having some stuff go a little sideways, having some high-energy [situations] that were kind of away from the game of baseball, we learned it now.

“I think we did a really good job of staying in the pocket, playing our game, staying in our clubhouse, focusing on what we do really well to be successful and not relinquishing any energy. It’s a beautiful game, we learned a lot and I’m just excited to keep this momentum moving forward.”

The Yankees, who finished a taxing stretch of playing 33 games in 34 days, improved to 25-5 this season when they score four runs or more.

After Bader’s two-run blast made it 2-1, Gleyber Torres added a solo shot in the sixth before Anthony Volpe doubled home Greg Allen in the seventh, all off hard-throwing Hunter Greene, who struck out 10.

That was more than enough offense for the Yankees’ pitching staff, led by Severino in his return from a strained lat that cost him the first month and a half of the season.

The right-hander tossed 4 ²/₃ innings and gave up just one run while striking out five. He was limited to 75 pitches as he continued to build up his workload after making only two rehab starts.

“I think we can all agree to say we got a whole lot better today,” Bader said of Severino’s return.

The one run Severino allowed came in controversial fashion in the first inning. After walking leadoff hitter Jonathan India on four pitches, Severino got two outs and then nearly got the third on a slicing fly ball to right field.

Jake Bauers made a sliding attempt and dropped it, with first-base umpire Nestor Ceja calling it a foul ball as India was rounding second.

The Reds challenged the play and replays showed that Bauers first touched it in fair territory, so it was overturned and called a double with India scoring (he had continued to run home even after Ceja called it foul in real-time).

But Aaron Boone’s argument — which led to his quick ejection — was that India should not have been awarded home, since the call on the field was foul and Bauers had no incentive to get up and throw home.

“I shouldn’t have gotten kicked out there — I’m saying my bad,” Boone said. “In the end, I think it was probably the right [call]. … I was just upset I didn’t get the explanation right away.”

It was a fitting scene for the final day of a nutty road trip, but true to how they handled the rest of this stretch, the Yankees did not let it bother them.

Instead, they came back to take the lead before the relief quartet of Albert Abreu, Jimmy Cordero, Wandy Peralta and Clay Holmes held it, capping off a series in which the bullpen threw 14 ¹/₃ scoreless innings.

“The energy was up this morning from jump street and I thought they went out and played really well,” Boone said. “I’m excited about how well this team is competing. Their level of — walk in with edge, prepare and compete — they’re doing that at a high level right now.”
