Ater the news of the New Zealander's signing I went to look for news of our Brazilian signing in December. The only word at that time was that we signed someone, without details.
Found something. His name's Rafael Moreno, an under-20 pitcher who won an award at a Pan-American youth tournament in November.
This site has a photo and a brief mention.
It also has a link to a Brazilian baseball site in Portuguese, where the info came from. There are supposed to be videos at the Brazilian site, but I couldn't find any.
