This Official MLB ball shows game use with a mark under the inscription, which is why the ball was removed from the game. On May 18, 2004 Randy Johnson became only the 17th player to throw a perfect game, and, at 40 years old, the oldest player. The inscription on the ball is written in blue ballpoint pen, and says, "Ball Used in Game, May 18, 2004, Perfect Game." It is signed by Randy Johnson just underneath. The baseball has an MLB hologram, #MR546240.
