The San Francisco Giants unveiled a new all-black jersey, appropriately enough, during Metallica Day at AT&T Park. Then they beat the Los Angeles Angels 5-4 this afternoon, in a wild finish. A ground ball struck L.A. pinch runner Taylor Featherston in the foot, and umpires called him out -- giving the Giants a victory.

This is the third consecutive year the club has held this Metallica-themed event, and the first since the Giants claimed victory in the 2014 World Series. Metallica, who are based out of San Francisco, had their own float in the city's celebratory parade last year. The group began taking part in these games the season after the Giants won the 2012 Major League Baseball championship.

Members of the band are on hand each time to participate in pre-game activities, and even sing the national anthem. There have also been some cool giveaways over the years, including a special-edition Metallica-themed inflatable guitar or pick set. Portions of the proceeds have benefited various charities, like the the Bay Area chapter of Little Kids Rock, and the Bill Graham Memorial Foundation.

Today, James Hetfield served as the public-address announcer for the reading the team lineup, referring to the Giants' No. 2 hitter as Joe “No” Panik. Metallica's biggest-selling album remains their 1991 self-titled release, typically referred to as the Black Album.
