Lee Seung-yuop (born 18 August 1976) is a retired baseball player and the current manager of the Doosan Bears. He 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 Samsung in the KBO. 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, and slugging percentage. Combined, across the KBO and NPB, Lee has also recorded more hits than any other native-born South Korean player. Professional career Lee started his career with the Samsung Lions of the KBO League in 1995 and played with them for nine seasons. He was the first player in the KBO League to hit 50 home runs in a season when he clubbed 54 in 1999. He set the single-season home run mark with 56 in 2003. In 2004 Lee signed with the Chiba Lotte Marines of Japan's Pacific League for two years. He signed a one-year contract with the Yomiuri Giants for 210 million yen, including a 50 million yen signing bonus, for the 2006 season. He batted fourth and played first base there.

In the next season, he greatly improved, making 30 home runs and 82 RBI while batting .260 in 117 games. He was selected to play for the Korea national baseball team in the inaugural World Baseball Classic in 2006. He batted .333 and led all players in the tournament with 5 home runs and 10 RBI.
