#8 Kwang Hyun Kim (2020-2021)
Coming over from South Korea on a two-year, $8 million deal prior to the 2021 season, Kim was an instant success for the club in 2020. During the shortened season, he put up an ERA of 1.62 in 39 innings, seeing him bounce between starter and high leverage reliever.
Kim continued his success across 106 innings during 2021, sporting an ERA of 3.46 while once again bouncing between the rotation and bullpen due to injuries. Based on how Kim would pitch when he was completely healthy, there is a chance he could have far surpassed his contract value had he not been bitten by the injury bug, but he still managed to be a very successful international signing.
