When writing historical fiction, I always make sure to research the time period extensively and adhere wherever possible to primary sources, except when I want to make a joke or something, in which case I just go ahead and change whatever. The story “Screwball” is a good example of these methods. The premise is true: Jack Dunn really did sign Babe Ruth straight out of St. Mary’s, and his nineteen-year-old son, Jack Dunn Jr., really did have the misfortune of competing against Ruth for a roster spot during their joint rookie season. There’s no way to know what kind of relationship Dunn Jr. had with Babe Ruth, but when I saw their names printed side by side and looked up their statistics, I couldn’t help but try to imagine it. I can’t say for sure what percentage of “Screwball” is true, but if I had to put a number on it, I’d guess it’s higher than Dunn Jr.’s lifetime batting average, but probably lower than Ruth’s. I’m grateful to the following sources for the insight they gave me into Ruth’s upbringing and baseball’s “dead-ball era.”
