If you ever attended a Seattle Mariners vs. San Diego Padres game at Petco Park, the chant of Vedder Cup can be heard throughout Gallagher Square moments before first pitch. Remember, there was no physical trophy awarded to the victor until now.
The Vedder Cup is an official event. The winner of the 2025 season series will receive a trophy designed by its namesake Eddie Vedder.
