Picked this one up on the Japanese version of joins.com, which appears to be a Korean publication.The article, quoting a scout from a Korean team, says the Cubs have signed high schooler Dong-Yub Kim to a contract with a $550k bonus. Kim is a 6′1, 181 lbs. outfielder who reportedly projects to have some power.
This is the first MLB signing out of Korea this offseason. I'll post more information if I can find any.
