ST. LOUIS — Fans have probably noticed Pete Crow-Armstrong’s latest celebration when he’s on the bases or rounding them — his hands behind his head, elbows out as he stretches back.“I’m reminding myself that this s*** isn’t too serious,” Crow-Armstrong said. “It’s gotta be fun. Relax.”Crow-Armstrong hears a lot from fans when he’s on the road. It’s rarely supportive. At times, he’s let it get to him, including a harsh exchange against a White Sox fan that he later apologized for.He understands that he has a target on his back. He’s not one to keep his thoughts to himself. He didn’t back down from controversial remarks about Los Angeles Dodgers fans and got an earful when the Cubs went out west.Crow-Armstrong is never really left wondering why it happens.“I don’t really leave a lot to the imagination,” Crow-Armstrong said. “Whether I’m oral with it or not, I’m loud out there.”His manager, Craig Counsell, has watched as Crow-Armstrong wears his emotions on his sleeve. He doesn’t want him to lose that swagger. But he wants him to learn how best to use that energy.“Some people need drama in their life — I’m not saying Pete does,” Counsell said. “But you got the friend who needs drama in their life, right? And there’s some people who aren’t interested in that. I think Pete likes the emotional part of the game, it’s good for him. He also has to show it; he has to let it out, too. It’s not always good. But he’s being himself. And I think that’s the most important thing.”The best way to channel those emotions, Crow-Armstrong has learned, is to let his play do the talking.“First and foremost, that is what I’d like to be able to do,” Crow-Armstrong told The Athletic’s Ken Rosenthal during a postgame interview on Fox: “We’ve seen in LA where I didn’t back up any talk that I may have said. So learning from stuff like that and always making sure that I’m doing the right things on the field first.”
