South Korean All-Star Kim Ha-seong's pursuit of his big league dreams has hit a snag before it began in earnest because of paperwork.

Kim's club, Kiwoom Heroes, asked the Korea Baseball Organization (KBO) last Wednesday to post the 25-year-old slugger for major league clubs. Later that same day, the KBO asked Major League Baseball (MLB) to inform its 30 clubs of Kim's availability.

Any interested big league club can negotiate with a posted player for 30 days. The window opens at 8 a.m. Eastern Time (ET) on the morning after MLB officially notifies its clubs of the player's status, and it closes at 5 p.m. ET on the 30th day.
