What happened: The Seattle Mariners marked Father's Day by featuring ceremonial first pitches as part of the club's holiday programming. The team highlighted the family-themed tradition tied to the June 21 date.

Why it matters: Father's Day first pitches are a recurring MLB ritual that ties clubs to their local communities and gives families a moment on the field. For Seattle, it reinforces the in-stadium experience the franchise leans on during the long regular-season grind.

What to watch: Watch for how Seattle's holiday push carries into its next homestand and whether the club extends the family-themed programming through the summer schedule.
