The backstory behind Petry's ability to shake off errors and avoid them re-entering his headspace is an interesting one.
He credits "a handful of people" for guiding him in this particular aspect of his development.
"My wife is good friends with a Major League Baseball player. He gave her advice to pass along to me, and I started to do it a few years ago. If you have one of those tough games, write something down, if you have a notebook or into your phone after a game, write down that mistake. You kind of replay it in your head and you write down what actually happened, and then rewrite it down a couple of times how you would've done it differently so if that situation comes up again, it's in your mind, the way you're going to react," revealed Petry. "I've heard pretty much the same thing from my dad, being a pitcher. You throw and you know you missed your pitch, a guy hits a home run off you, you're going to learn from that and know you can't make that mistake again against that player. It's kind of that same mindset."
Assistant coach Luke Richardson has also proven to be a key figure in this department for the smooth-skating rearguard, keeping Petry and the rest of the team's rearguards' spirits up if things go awry.
That encouragement and support goes an extra long way.
"He's helped me throughout his time here. His calming presence behind the bench will help all the young guys as well," stressed Petry. "He does a good job at just calming you down and making sure that the mistake you made the shift before doesn't carry over to the next shift or the shift after that. The mistake is over and your next shift is most important."
