Players that accrue nine years of service time in Japan's Nippon Professional Baseball or the Korea Baseball Organization are considered free agents. Such players are eligible to pursue opportunities in any league, including Major League Baseball, without being subjected to the Korean or Japanese posting systems.
The Orioles signed Korean outfielder Hyun Soo Kim to a two-year contract in December 2015, without having to go through the posting process. Kim played his first full professional season in Korea during 2007, at the age of 19, and reached nine years of service time in '15. Had he wished to test the Major League market sooner, he would have had to request that his Korean club post him for bidding among Major League clubs.
