Luis Castillo, a third baseman from the Dominican Republic, has agreed to sign with the White Sox for $450,000.

Castillo, 16, is 6-foot-2, 205 pounds with a sound righthanded swing and plus power. Castillo played in the Dominican Prospect League and trained with Carlos Hernandez, who is known as "Cambo."

Earlier this month the White Sox also signed 16-year-old Dominican shortstop Johan Cruz, who some scouts considered one of the better shortstops on the island for July 2.
