Major League Baseball's international signing window opened Tuesday, and the White Sox quickly struck by landing one of the top players on the market. Dominican Republic native Micker Adolfo Zapata, 16, received a $1.6 million signing bonus from the White Sox, the largest ever given by the franchise for an international signing. The 6-foot-3, 225 pound outfielder was rated as the No. 2 international prospect by and No. 9 by Baseball America. “Micker is a terrific young man who is tremendously talented,” White Sox general manager Rick Hahn said Tuesday from the Dominican Republic. “As we’ve gotten to know Micker and his family, we’ve been even more and more impressed. We cannot say enough about his baseball potential and his future with the White Sox.”
