Kim Sung-Keun (Hangul: 김성근, Hanja: 金星根) (born December 13, 1942 in Kyoto, Japan) is a retired South Korean left-handed baseball pitcher and the manager for the Hanwha Eagles. He has spent his childhood as a resident of Japan and adopted a Japanese name (Seikon Kanebayashi), but remains a Korean citizen, thus making him a Zainichi Korean. Kim led the SK Wyverns to victory of the 2007, 2008 and 2010 Korean Series.
