The Yankees’ Adam Ottavino problem is not going away.

The reliever’s playoff struggles continued Tuesday in Game 3 of the ALCS, failing to record an out for the third time in six appearances this October and getting charged with two critical runs in the Yankees’ 4-1 loss to the Astros.

After a mostly dependable regular season as one of Aaron Boone’s high-leverage bullpen arms, Ottavino has allowed nine of 16 batters to reach base this postseason — giving up six hits, three walks and three runs.

“I’m not going to let it define me,” Ottavino said. “I’m not going to dwell on a couple pitches here and there. Obviously it’s frustrating. These are the types of games I want to be in. This is the reason I came to this team and everything I’ve wanted my whole life. I want to do better. I want to get out there again, that’s it.”

Ottavino entered the game Tuesday to start the seventh inning with the Yankees trailing 2-0. He immediately got ahead of George Springer for a 1-2 count before throwing three straight balls to walk the Astros’ leadoff man.

Jose Altuve then ambushed Ottavino’s first pitch for a single on a perfectly executed hit-and-run, with his ground ball finding the open space through the right side of the infield.

Boone jumped out of the dugout to pull Ottavino and call on Zack Britton to try to clean up the mess. The crowd serenaded Ottavino with loud boos as he walked off the field, and three batters later, the deficit grew to 4-0.

“I felt confident. I felt determined,” Ottavino said. “I got ahead of the first guy, ended up walking him. Then I gave up a hit on the next pitch and that was it. It happened kind of quick and it was frustrating, but I don’t know. I don’t really have a good answer for it.”

Ottavino insisted his problem is not pertaining to his confidence, physical status or mechanics. He said his mechanics were out of whack two weeks ago but he has since fixed them. The results have not come with it.

“We’ll continue to use him,” manager Aaron Boone said. “Just got to be a little sharper with his command, a little sharper with his stuff, and we’re going to need him moving forward.”

Ottavino finished the regular season with a 1.90 ERA, but his subpar pitching down the stretch has bled over into the playoffs. In his final seven outings of September, Ottavino allowed seven hits, five runs (three earned) and four walks over six innings.

“I’ll stay ready for my next chance and work really hard behind the scenes and be confident when I go in there again,” Ottavino said.

“That’s pretty much all I can do.”
