Lewin Diaz, the No. 15 international prospect for July 2, has signed with the Twins for $1.4 million.
Diaz, a 16-year-old Dominican lefty, has raw power that ranks among the best in Latin America. Some scouts also like his swing, although he’s still learning to tap into his power in game situations. At 6-foot-4, 210 pounds, Diaz has played outfield and first base in the Dominican Prospect League and projects best as a first baseman. He trains with William Valdez.
