Someone told me if you bowl in a league in Mexico you can choose to have your average reported in the book or not? Is this true?
Never heard of anything like this before. I mean, outside of what is the blazingly obvious answers leading to "hell no" (different country, different national bowling governing body, etc.), Imagine someone like Pat Healey Jr. (when he lived in Mexico City) struggling in a league down there, gets his average listed at the USBC, comes up here, and crushes it and Nationals. Think of the floodgates that would have opened.
Now, with that, I will caveat that by saying that at one of the collegiate tournaments (I want to say it was NAIA or Sectionals last year) There was a men's and women's team there from Windsor, Canada (just across the river from Detroit), and Cannizzaro and Smith went into how they were allowed in, as it was a USBC event, but I can't remember the college. So it is possible.
Another way I could see it happening is if it is a WTBA league, which would be the governing body above the USBC. So it all depends.
There's ways, but directly from a simple league, more than likely not.
