10:40am: Major League Baseball has taken the procedural step of requesting a status check on Yoon from the Korea Baseball Organization, according to a Yonhap News report (hat tip to Dan Kurtz of MyKBO.net). The KBO confirmed that Yoon is indeed a free agent and able to sign anywhere.
TODAY, 9:05am: Yoon is traveling to the United States on Wednesday in hopes of securing a contract, according to a report from Korean news outlet Arirang (video link).
JAN. 10: The Red Sox and Twins are both interested in Korean right-hander Suk-Min Yoon, tweets Peter Gammons of the MLB Network and GammonsDaily.com. Gammons also spoke with one executive who guessed that the Giants are a good fit for Yoon as well. In an article at GammonsDaily.com earlier this week, Gammons noted that Yoon is one of many depth options still on the radar for the Red Sox. Cuban right-hander Raicel Iglesias is also among their potential targets.
It's been quiet on the Yoon front this offseason, as agent Scott Boras has had his hands full in negotiating contracts for Shin-Soo Choo, Jacoby Ellsbury and Mike Pelfrey while also trying to build the markets for Stephen Drew and Kendrys Morales. As MLBTR's Tim Dierkes noted in his free agent profile of Yoon, the 27-year-old has a low-90s fastball and was considered the second-best pitcher in the Korea Baseball Organization behind Hyun-jin Ryu prior to Ryu's jump to MLB. He has experience as both a starter and a closer.
The Twins have been connected to Yoon multiple times this offseason, but it's unclear whether or not they'd still have significant interest after adding Ricky Nolasco and Phil Hughes and re-signing Pelfrey. He could slot into Minnesota's bullpen, but the relief corps was one of the few strengths for last season's 96-loss Twins team.
