Yeah—I know most don’t get that. Which is why I referenced round or pick dependent. For example, the slot for the last pick in the 10th round (316) is $148K. Not chump change, either, but not life changing.
I assumed, though, that the majority of guys who make it to the majors are selected in the first 10 rounds of the MLB draft (excluding international signees). If true, then most have some signing bonus, in addition to their MLB salaries.
(of course given how low minor league pay is, they probably use their signing bonus money to supplement until getting promoted).
