KANSAS CITY, Mo. — Dellin Betances wants Aroldis Chapman back from the DL as soon as possible. However, while the left-handed closer recovers from rotator cuff inflammation that could shelve him until the middle of June, Betances said the final three outs of the game are in good hands.

“I don’t think I have to prove my value. These guys know what I can do,’’ Betances said before the Yankees’ 7-1 win over the Royals in which he did not pitch. “You got to have confidence, and I believe in myself.’’

Betances’ first stab at closing came after last year’s trading deadline, when Andrew Miller was dealt to the Indians and Chapman to the Cubs.

From Aug. 1 to the end of the season, Betances was presented with 14 save chances and flushed two of them. In the 23 games Betances appeared in, the Yankees went 19-4. His ERA was a bloated 4.37 and batters hit .224.

That was a stark contrast to what Betances had done working in front of Miller and Chapman for the first four months of the season, when he had a 2.50 ERA and hitters batted .191. He did go 0-for-3 in save chances.

The final three outs are different for some relievers, but Betances said he isn’t bothered by the pressure. Nor is he going to think about club president Randy Levine predicting Betances will be great replacing Chapman.

“I’m not worried about Randy Levine and what he’s trying to say,’’ Betances said. “Obviously there was the thing a couple of months ago, but I’m focused on the team and trying to help the team win.’’

After winning an arbitration hearing in which Betances was awarded $3 million instead of the $5 million he was seeking, Levine pointed out Betances wasn’t a closer as the reason the Yankees won.

“Anyone who knows the process knows the history is very well established that $5 million goes to elite closers, people who pitch the ninth inning and have a lot of saves. Dellin didn’t have that record,’’ Levine said in February. “The agent took him to a case in effect like me saying, ‘I am not the president of the Yankees, I’m an astronaut.’ I am not an astronaut, and Dellin Betances isn’t a closer. This was an attempt to use a player to change the market.’’

On Tuesday, Levine said of Betances: “He is going to do great. He is ready. I have full confidence he will do a great job.’’

As for the ninth inning, Betances has a simple view of it.

“The only difference is you either shake hands or go home upset. There is nothing different because you have to make pitches. You have to be the aggressor and try to get some outs,’’ Betances said. “The only difference is if you put it in your mind that you have to do something different, you’re going to get yourself in trouble.’’

Joe Girardi said the same talent that has made Betances an All-Star the past three seasons is the reason he believes he can handle the ninth.

“He has really good stuff, that’s the bottom line for me. He had some success and he had some struggles, but that isn’t unusual when a guy is moved back in the bullpen. There are a few ups and downs, and I don’t see this being an issue,’’ Girardi said. “You could argue the last few years he has been the best reliever in the game, and you can put his numbers against anyone. I don’t see why it won’t translate to the closer’s role.’’
