The winner of the annual series between the San Diego Padres and Seattle Mariners will now win the Vedder Cup, a trophy designed by Pearl Jam lead singer Eddie Vedder.This award is part of a charity drive benefiting the Epidermolysis Bullosa Research Partnership,

Eddie Vedder is bringing his love for Seattle and San Diego to Major League Baseball! On Friday, MLB announced that the Mariners and Padres will compete for the Vedder Cup every year, and will partner with the rockstar’s charity to support Epidermolysis Bullosa research.
