What happened: The Seattle Mariners posted a Father's Day message to their fan base, joining a wave of clubs across leagues marking the holiday. The lighthearted note leaned into the dad theme as the team carries on through its regular-season schedule.

Why it matters: Holiday messaging is part of how franchises connect with their fan base between games, and Father's Day is one of the most widely observed across the sports calendar. The Mariners' note lands alongside similar messages from teams in the NFL and WNBA marking the same day.

What to watch: Attention turns back to the diamond as the Mariners continue their regular-season slate.
