Damn Yankees by Douglas Wallop, originally published 1954. A middle-aged die-hard long-suffering
Washington Senators fan makes a deal with the devil to help his team try to beat out the New York Yankees and win the pennant. A hit Broadway musical and movie musical were based on it. Trust me, the characters do not break into song and dance routines in the BOOK. I read it twice as a kid.
