“There were times where we were kids and our dad had us in the backyard and he would throw us pitches and we’d hit it with just those little mini big bats and he would call out a count or a situation,” Josh Naylor told Cleveland.com in 2024. “Bottom nine, game on the line and you’ve got to get a home run to win it type of thing.”

Josh added: “You have to be ready for those moments, and I think both our parents prepared us. Playing games as a kid prepared us.”
