This needs a stretch.
Worse Than A Curse is a story in by Scooby-Doo! #130 DC Comics.
Scooby and the gang solve the mystery of the curse of "Crybaby" Bodine, who haunts baseball's Wenfrey Field.
Beau Owen Buford
The gang found a briefcase in a locker with his initials on it and a coded message that said that he was making a secret wager against his own team, the Coolsville Blue Sox.
He wanted his team, the Empire City Emperors, to win the final game of the Universal series that night.
He wanted to be taken of the roster of the Coolsville Blue Sox that night because he thought the pressure there was too much.
He did put his life savings on the Empire City Emperors to win.
Beau Owen Buford as Crybaby Bodine's Ghost
A coded betting form found by Velma in his monogrammed briefcase revealed that he had made a secret wager against his own team, the Coolsville Blue Sox.
Terrence Griep adds a little spice to "Worse than a Curse" through his dialogue for the Gang who look splendid in Karen Matchette's slightly askew style. The trouble is that the mystery is too easy to solve and the ghost isn't all that spectral.
