It's not like Erik made that up. I believe he's paraphrasing a story from "Crazy 08". That said, it's highly suspect that any ballplayer would have actually taken up such an impromptu proposition, especially for that little (MLB players averaged $2,500 a year in 1908). The only dollar amount that I know of from back in that era where someone was actually paid to throw a game (other than the Black Sox) was $50, which was paid to a Reds pitcher in 1918.
