Hitting four home runs in a single game is such a rare accomplishment that more perfect games have been thrown than four home run games. Fifteen batters have achieved this monumental feat, six of them having signed and inscribed this ONL Giamatti baseball: Willie Mays (sweet spot), Rocky Colavito, Mark Whiten, Joe Adcock, Mike Schmidt and Bob Horner. The signatures grade a strong 9 and come with a letter from PSA/DNA.
