Posting system (KBO)

To be eligible for posting, a player must have first played at least seven years in the KBO.

[1] Under this system, when a KBO player is "posted," MLB holds a four-day-long silent auction during which MLB teams can submit sealed bids in an attempt to win the exclusive rights to negotiate with the player for a period of 30 days.

If the MLB team and the KBO player agree on contract terms before the 30-day period has expired, the KBO team receives the bid amount as a transfer fee, and the player is free to play in MLB.

The eight players that have been acquired by MLB teams through the posting system are Choi Hyang-nam, Hyun-jin Ryu, Jung-ho Kang, Byung-ho Park, Kwang-hyun Kim, Ha-seong Kim, Jung-hoo Lee, and Woo-suk Go.

Of the South Korean-born players who have played in MLB,[2] seven have entered the league using the posting system.
