Metallica guitarists Kirk Hammett and James Hetfield rocked the national anthem last Friday (April 26) during seventh annual "Metallica Night" at Oracle Park, the home of Major League Baseball's San Francisco Giants as the team battled the New York Yankees. Now, fans have a chance to win the guitars the band used for the proceedings.

That's right, not only can Metallica lovers enter the sweepstakes to win Hammett or Hetfield's game-used axes, they can also bid to win the second base that Hetfield "stole" in the middle of the game. It's been signed by all four members of the band. Watch the Metallica guitarist and vocalist capture the base in the Instagram clip below.

As if that wasn't enough, the MLB is holding its own auction of game-related Metallica gear. Check that out here. Available for bidding are multiple Giants game jerseys signed by the band, a signed baseball, plus a signed bat.

Proceeds from the guitars and stolen base sales go to benefit Metallica's All Within My Hands Foundation, dedicated to creating sustainable communities by supporting workforce education and helping the fight against hunger.

Below, watch Metallica play the anthem during the game at San Francisco's Oracle Park last week. See the band's upcoming tour dates after the video.
