Well, digging it through, Vance started 171 games in Ebbetts Field for the Dodgers from 1922 to 1932. Even before looking at the runs/game results, an oddity emerges that doesn’t quite negate Bressler’s memory but certainly doesn’t fit into it: Vance only started 12 games in Ebbetts Field on Mondays. That seems a bit low (less than one start in 14) given that he had a brilliant plan to use that day to his advantage.
Don’t get me wrong: he shouldn’t have had one-seventh of his starts occur on Monday. Baseball traditionally likes having weekend series (when more fans can attend), causing Monday to be a frequent travel day. Also, back in those days, there were frequent doubleheaders on weekends, especially Sundays. Still, one would expect his managers to try to ensure he started Monday, when possible.
From 1922 to 1932, Brooklyn hosted 84 home games on Monday, meaning that Vance started exactly one out of every seven. On non-Mondays, he started one-fifth of their home games. Below shows how many starts Vance had in Ebbetts from 1922 to 1932, how many home games the Dodgers played on that day, and what percentage Vance was responsible for.
