Venezuela - Renteria; Ascanio and Blanco (40-man roster)

Interesting how some teams are built vs. others. The Braves don’t have a single Asian (unless you count Australia, where Atlanta was early to scout) while every other team mentioned has at least one, and many have several. Is Wang (China) from the mainland or Taiwan?
Considering just how multicultural San Diego is, it’s rather shocking that not a single Padre was born outside of the USA. The closest culturally are probably Jose Cruz of Arroyo, Puerto Rico, and Adrian Gonzalez of San Diego who (I believe) played for Mexico in the WBC and has lived in Mexico. Nine Californians, FWIW, including four from San Diego County (brothers Marcus and Brian Giles as well as the aforementioned Gonzalez and pitcher Heath Bell).
And those guys weren’t American? All three major-league Alomars and Carlos Baerga were born in Puerto Rico, off the top of my head.
