The Baseball Spectre is a ghost of a baseball player who interrupts the game in the new stadium above the old Potter Stadium. He threatened a baseball player not to break his record or he will kill everyone in The Unnatural. As he appeared the second time, he takes out the lights above mentally. He was stopped when Shaggy fired him from a cannon and into the sky net. Scooby unmasks him revealing the man named Bob Taylor who wanted to keep the record of his best friend's home run from being broken. The Spectre is voiced by Frank Welker.
