The San Francisco Giants recently hosted the third annual Metallica Day at AT&T Park. The band participated in many different activities at the game. Lars Ulrich threw out the first pitch, while James Hetfield and Kirk Hammett performed the National Anthem. Meanwhile, Robert Trujillo announced that it was time to “Play Ball,” while Hetfield also  read the team’s lineup.

The MLB Network was at the game, and you can check out commentator, metal fan and former MLB player Sean Casey interviewing the band in the video above. One of the funniest parts of the interview is Casey's chat with Ulrich about throwing out the first pitch.

Ulrich admitted he's not the most knowledgeable baseball fan. "I'm going to throw right around the [pitcher's] mound," Ulrich says. "The first year I went out past the rubber, because I thought you were supposed to stand behind the rubber – so I handicapped myself by five feet there. When people give me beef for not knowing more about it, I say 'Listen, where I come from, baseball is called 'rounders,' and it's played by 12-year-old girls."

One of major league baseball's all-time best closers was Mariano Rivera of the Yankees, who used Metallica's "Enter Sandman" as he walked from the bullpen to the pitcher's mound.

In the video, Hetfield comments, "If I was pitching, it would be the song 'Black Sabbath' from Black Sabbath, the big ominous intro when I come walking out."
