Aggregate productivity metrics are...difficult. But if one assumes that salaries are roughly proportional to value produced, it's not uncommon to have >10:1 ratio in the top professional tier of a sport, much less the whole of a professional sport.
E.g., the NFL has about a 25:1 ratio https://www.comparably.com/salaries/salaries-for-nfl-footbal...
MLB has a 700k minimum salary, a 1.1M median salary, a 4.4M mean salary, and a top salaries of $43.3M (that's a more than a 6:1 mean to minimum, and almost a 10:1 maximum to mean ratio, and over 60:1 overall ratio.)

> Being 10 times faster or 10 times stronger is beyond human limits.
“Fast” and “strong” measured in ways in which this is true are contributors to value produced, but not the measure of value produced by a player. A wide receiver that is the same in all other ways but runs half as fast as the fastest in the league isn't contributing half as much value.
