The LG Twins of the Korean Baseball Organization have decided to let their closer Woo-Suk Go negotiate with Major League Baseball teams in hopes of getting a suitable contract. Last week, it was reported that MLB had done a status check on Go, meaning at least one team was interested in signing the right-hander, which started the potential posting process.

Once Go is officially posted, teams will have 30 days to work out a potential deal that includes a release fee. That fee would be paid to the LG Twins, and if the Twins don’t like the amount that the fee would be, they can decide to keep Go.

Here’s a breakdown of how the release fee works:

  • Contract worth less than $25 million: 20% of contract value
  • Contract worth $25 million to $50 million: $5 million plus 17.5% of amount over $25 million
  • Contract worth more than $50 million: $9.275 million plus 15% of amount over $50 million

The 25-year-old has a 2.39 ERA, 334 strikeouts, and 139 saves in his last 273 1/3 innings covering the last five seasons. After posting a 1.48 last season, Go struggled a bit this year with a 3.68 ERA in 44 innings. He did post a career-best 12.1 K/9 and allowed only two home runs.

Go averaged 95 mph on his four-seamer this year and topped out at 98 mph. He also throws a slider in the 87-91 mph range and a curve as well.

Kiwoom Heroes outfielder Jung-Hoo Lee, who is Go’s brother-in-law, is also expected to be posted this offseason and MLB Trade Rumors has him ranked as their No. 15 free agent.
