In April, the Harpers had a creative way to reveal the newborn's gender at Citizens Bank Park during a game.Harper's Phillies teammate Trea Turner was made to get in touch with their doctors to share the first baseman's upcoming baby's gender. He chose a bat between a blue and a pink one. Harper took the plate with a blue bat to confirm that they're expecting a boy.Kayla Harper posted the moment on social media, with the caption:"Baby BOY Harper coming 2025 🩵 We wanted to be surprised and find out together, so we recruited Trea for some help. The doctor texted him the news and he was given two bats — one pink, one blue. Right before Bryce’s first at-bat, Trea gave him the bat that matched the baby’s gender. We’re so excited to add another boy to the family to even us out."Bryce Harper is a parent to Krew Aron (born 2019), Brooklyn Elizabeth (2020) and Kamryn Ray (2024).
