Rudy M. Arias
Another from the Lumpkin request above.
This photo comes from the Miami (FL) Nueva Herald of June 24, 1976. I think the uniform is that of the Miami Cubans. The accompanying article is written in Spanish, so I had some difficulty with it. My guess is that the Miami Cubans were a team formulated for some international competition over the summer. The description of Arias seems to suggest that he has potential to become a major leaguer. A subsequent edition of the Nueva Herald displayed a photo of him in a Mariners' uniform, but unfortunately the photo quality was horrible and totally blacked out his face.
