Lee Seung-yuop (born August 18, 1976) is a retired baseball player, who spent most of his career with the Samsung Lions of the KBO League. At the age of 26, he became the youngest professional baseball player in the world to hit 300 home runs. He formerly held the Asian home run record of 56 homers in a season, established in 2003 while playing for the Samsung Lions in the Korean league. The record was broken by Wladimir Balentien of the Tokyo Yakult Swallows, on September 15, 2013, when he hit his 56th and 57th Home Runs of the season against the Hanshin Tigers of the Nippon Professional Baseball League. He holds the KBO records for career home runs, runs scored, RBIs, total bases, slugging percentage and OPS. Combined, across the KBO and NPB, Lee has also recorded more hits than any other native-born Korean player.
