TAMPA — Luis Severino has had his issues pitching in the postseason and after the revelations that the Astros cheated in the 2017 playoffs, he’s left to wonder how much of it was his fault.

Severino admitted he was angry when he initially heard MLB found that Houston used an illegal electronic sign-stealing scheme that helped them win when they beat the Yankees in seven games in the 2017 ALCS en route to a World Series title.

“I was mad because I remember how many times I would look in the mirror at my mechanics to see if I was tipping pitches,” Severino said after pitchers and catchers reported to Yankee camp on Wednesday at Steinbrenner Field.

And while he and other members of the Yankees’ pitching staff tried to make sure they weren’t tipping pitches, they now know Astros hitters were getting their pitches in real time.

“A lot of things go through your mind when you’re pitching against a team that good,” Severino said. “You think, ‘Am I tipping?’ and spend hours in the video room looking and saying ‘What am I doing?’ Then you hear what the problem is and it wasn’t even tipping.”

And he’s uncertain if the Astros’ cheating ways extended to last year’s playoffs, when they again beat the Yankees in the ALCS, this time in six games.

“I’m not sure about buzzers,’’ Severino said. “Like a lot of players said, [MLB] did the investigation and didn’t find anything. I don’t know. The only thing I’m sure of is what they said, that [the Astros] were using cameras and stuff [in 2017].”

But the right-hander insisted he’s not going to let it impact this season.

“When something like that happens, you think about a lot of stuff,” Severino said. “But right now, it’s in the past.”

And he appreciated Marwin Gonzalez apologizing for his actions while he was with Houston. Now with the Twins, Gonzalez became the first hitter to express remorse for his role in Houston’s sign-stealing.

“Marwin Gonzalez apologized and that’s great,” Severino said. “They [made] a little mistake. They regret it and now we have to move forward and keep competing.”

Severino added he wasn’t looking for personal apologies from individual Astros players, but he does want to speak to some of them to find out who was responsible.

“[MLB Commissioner Rob] Manfred already did everything he could to the players and coaches,” Severino said. “[The players] don’t have to apologize to me… For me, it’s already in the past. We can get mad, but we can’t change anything in the past. It’s already done.”

Severino said he’s done thinking about what happened in those playoff series.

“A lot of things could have been different, but we can’t change it,” Severino said. “We need to be focused on 2020 and try to win.”

For Severino, the best way to do that is to stay healthy, something he wasn’t able to do a year ago.

“For me, this is a key year,” Severino said. “The main thing for me this year is being healthy all the way to the playoffs and World Series.”
