The San Diego Padres and Seattle Mariners announced Friday they've officially dubbed their six-game series each season the Vedder Cup, complete with a trophy to determine which city can claim credit for Pearl Jam frontman Eddie Vedder.

The Padres will join rock star Eddie Vedder in creating the real Vedder Cup, the prize for the victor in their six-game season series with Seattle.

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.
