Metallica went out to the ballgame Monday night for the sixth annual Metallica Night at AT&T Park in San Francisco. Members of the band were at the stadium to watch the San Francisco Giants host the Washington Nationals. Guitarist Kirk Hammett got the night started with a performance of the national anthem and then the band threw out the first pitch. A portion of the proceeds from the night's ticket sales go to the band's All Within My Hands Foundation.
