I think you're misunderstanding him. What he meant was the cultural norm (or more accurately imo: "the stereotype") in America around black people is that they can't swim, don't like baseball, don't listen to rock/country or play golf.

This got me curious and a cursory search seems to hint that blacks are proportionately represented (as per the percentage of the US population that identifies as such) in baseball, and disproportionally represented in sports like basketball.

For baseball: > 60% of the players in the league are White, while 28.53% are Hispanic. That leaves roughly 12% available for Black and Asian players[1]

For basketball: > NBA in 2015 was composed of 74.4 percent black players, 23.3 percent white players, 1.8 percent Latino players, and 0.2 percent Asian players.

In that exactly as many black people play baseball professionally as you'd expect, just looking at population numbers.

Interesting. So it seems that enjoying baseball is a form of mild insanity that is distributed evenly across all races ;)
