Jason Grilli Onstage With Pearl Jam: "Next Year, It's Our Fuckin' Year"

Pearl Jam played in Pittsburgh Friday night and since Pirates closer Jason Grilli's entrance song is "Whipping," he joined the band onstage to fire up the crowd.

Grilli was fired up himself and told the crowd he will pitch his balls off for the city and that next year would be the Pirates' year. Then PJ launched into "Whipping" and Grilli danced around like a weirdo. Excellent times.
