The Odd Multi-Sport Athlete That I Promised to Mention

I skipped this post yesterday since I was busy telling about my crash while running.  Back to business with the oddest of the two-sport athletes I found listed online.

Juan Marichal is listed as a two-sport athlete.  It is mentioned that he participated as a soltadore in a cockfighting circuit in the Dominican Republic.  What?  Really?

I'm not going to pretend to understand much about the cockfighting circuit or how it got into a Seinfeld episode.  I do want to know what a soltadore is.  Time to find out what Juan's job was.

It seems like that is the job of putting the animals into the ring for the fight.  How does that make him a two-sport athlete?
