Alberto Sanchez, a 16-year-old third baseman from the Dominican Republic, has signed with the Marlins for $125,000.
Sanchez, who is 6-foot-1, 180 pounds, was one of the more polished hitters in the Dominican Prospect League leading up to July 2 this year thanks to a sound righthanded swing. He has projectable power and projects to have a big, physical frame, though he's more of a line-drive hitter right now.
He would need to put in a lot of work to stay at third base, so he may end up in left field. Sanchez trained in Santo Domingo with Maximo Rombley.
