Luis Severino can’t say for certain tipping his pitches led to a mostly lousy second half last season and the righthander getting shelled by the Red Sox in Game 3 of the American League Division Series.

But he is well aware of the speculation and video that went viral of Boston’s Jackie Bradley Jr., in the early going of that game correctly calling out pitches in the dugout.

“I’m still not sure, but someone sent me a video of Jackie Bradley talking about ‘fastball’ or stuff like that,” Severino said Monday at the Yankees' minor-league complex. “I’m looking forward to that [video of his starts] to see, but if I see something I will definitely change it.”

Severino finished last season 19-8 with a 3.39 ERA – solid numbers to be sure – but the season still left a bitter taste for the 24-year-old. The righthander, after beating the Red Sox on July 1, was 13-2 with a 1.98 ERA and very much an AL Cy Young candidate. But from that point he struggled, going 6-6 with a 5.67 ERA over his last 14 starts. Severino did go 2-1 with a 2.04 ERA in his final three regular-season starts and threw four shutout innings against the A’s in the AL wild-card game, but he allowed six runs over three innings of the 17-1 loss to the Red Sox in Game 3.

“Of course,” Severino said, asked if he altered his offseason routine because of the rough second half. “I changed a little bit my workout. I think maybe I got a little tired toward the end [of the season] so I’ve been working on that. Also my mechanics. I’m not sure but maybe I was tipping some pitches. I want to make sure none of that happens.”

He said in the video work he has done, he hasn’t seen anything “consistent” suggesting he was pitch-tipping but will keep looking at it this spring. If he was, Severino said he wasn’t angry at Bradley or the Red Sox or anyone else for capitalizing.
