Luis Severino put some demons to rest with his dynamic performance against the Twins in the Yankees’ series-clinching win in Game 3 of the ALDS.

His four shutout innings in Minnesota paved the way for the Yankees, and the right-hander said Aaron Boone credited him not just with pitching well in an important game, but in getting out of jams in both the second and third innings to help save the bullpen.

“Boone told me that saved the game, just because of how he was able to use the bullpen after that,’’ Severino said after the Yankees worked out in The Bronx on Thursday in preparation for the ALCS, which begins Saturday.

Whenever Severino takes the mound again — which will almost certainly be in one of the first three games — he’ll have another strong postseason outing on his résumé after having to answer for his ugly outing against the Twins in the 2017 wild-card game as well as his dud in Game 3 of the ALDS against the Red Sox a year ago.

“Hearing about those things, either about last year or the Twins in ’17, really didn’t bother me,’’ Severino said. “I know what went wrong in both games and I knew I could fix it.’’

Whether those issues are solved for good is up for debate and he’ll get another opportunity in the coming days.

Facing the Twins, Severino got into — and out of — a bases-loaded, no-out situation in the second without allowing a run and got another important strikeout to end the third with two runners on.

Each time, Severino yelled as he left the mound.

The reactions weren’t simply because of the importance of the moment. They also had to do with the fact he missed most of the regular season with rotator cuff inflammation and a lat strain and is happy to contribute at this point of the season.

“I feel great and I’m ready to go,’’ Severino said. “I just want to go out and win. The rest of the team did the job in the regular season to get here when I was injured and now it’s my turn.’’

And the fact he’s thrown just 16 innings since spring training could work to his advantage.

“I feel strong,’’ said Severino, who pitched 12 innings in three regular-season starts in September and four innings versus the Twins. “Sometimes I feel too strong and let the ball go too hard, but I’m on the right track and am looking forward to keeping it going.”
