PEORIA, Ariz. — The victor in the annual season 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, an organization co-founded by Eddie and Jill Vedder. The charity is dedicated to funding research to discover treatments and cures for epidermolysis bullosa, a condition that causes blistering of the skin.

The Padres and Mariners play two series against each other every season. This year, they meet May 16-18 in Seattle and Aug. 25-27 in San Diego.
