The Los Angeles Dodgers have signed South Korean high school pitching prospect Jang Hyun-seok. The signing: Jang's agency, Leeco Sports Agency, announced the 19-year-old pitcher's agreeance to a $900,000 signing bonus as an international free agent on Wednesday. A "tough decision": Although Jang, listed at 6 feet 2 inches tall and 198 pounds, was expected to be first pick in the Korean Baseball Organization, he announced last week that he would be bypassing the draft to play in the MLB.
