Wait. The Padres and Mariners are making the “Vedder Cup” official? Talk about a grass-roots “campaign” sprouting out of press box shenanigans in Peoria, Ariz., and climbing all the way up the corporate ladder.

Vedder, the frontman of Pearl Jam, was a one-time resident of both San Diego and Seattle. The Mariners and Padres will compete for the Vedder Cup trophy, which features a guitar provided by the rock legend himself. That is set to be unveiled later during this season before the two clubs meet.
