The Twins have agreed to terms with 16-year-old Dominican shortstop Miguel Angel Sano, his agent said Tuesday, and will pay the highly touted hitter a $3.15 million signing bonus. Rob Plummer said he expects the deal to be finalized this week, likely today. The issue most likely holding up the finalization is one that has been nagging Sano and Plummer all summer while teams have pursued him. Sano is reportedly 16 years old, but questions about his age have been serious enough for Major League Baseball to look into it. MLB did an identity and age investigation this summer, and though his identity checked out, according to reports, the league wasn't able to make a conclusion on Sano's age. The Twins were one of several teams interested in Sano, along with the Pirates and Orioles, and Plummer said Sano is "super, super excited" to sign with Minnesota.
