Santo Domingo.– Miguel Sano has been granted a U.S. work visa, completing his $3.15 million bonus deal with the Minnesota Twins, according to a report by ESPN Deportes.

Sano had been in the center of rumors about the possible falsification of his personal documents, which some believed he lied about his age. Sano and his family were subjected to DNA tests to confirm parenthood, and a study of Sano's bones concluded that he was between 16 and 17 years old.

This follows recent concerns that some Dominican prospects may have been using false names and birth documents to lower their age and get higher signing bonuses.

His professional baseball career would start in 2010, most likely in the Pacific Gulf Coast League, Plummer said.
