Former Cardinals southpaw Kwang-Hyun Kim is returning to South Korea. He’s agreed to a four-year deal with his former Korea Baseball Organization team, the SSG Landers, reports Jeeho Yoo of Yonhap (Twitter link). The John Boggs & Associates client receives a $12.3MM guarantee, the largest deal in KBO history.

Daniel Kim reported this morning that the Landers had tendered a status check on the southpaw. That indicated they were interested in bringing the Seoul native back to South Korea, and he and the team wrapped up a deal fairly quickly thereafter. Kim starred for the Landers (then known as the SK Wyverns) for the entirety of his career before making the jump to the MLB over the 2019-20 offseason.

He’ll now return to the Incheon-based club, with whom he made his professional debut as an 18-year-old back in 2007. By his second season, he’d developed into a high-end starting pitcher. He posted a 2.39 ERA across 162 innings during his sophomore campaign, kicking off a stretch of three consecutive years with an ERA below 3.00. Kim didn’t quite sustain that kind of run prevention long-term, but he’d log 130+ frames with a sub-4.00 mark in five of his next eight seasons. That included a 2.51 ERA in a personal-best 190 1/3 innings in 2019, a strong showing that set the stage for him to come to North America the following winter.
