Born January 10, 1964 in Seoul, South Korea. After only five amateur bouts (4-1), the 5’ 4” Yuh turned professional in 1982 at the age of 18 under the tutelage of trainer Kim Jin Kil and manager Hyunchi “Thomas” Kim. The diminutive ring technician would not taste defeat in 36 bouts over the next nine years.
Yuh won the vacant OPBF light flyweight championship with a third round kayo over Edgar Inocencio in 1984. After 18 wins (14 by decision and 4 by knockout) he won the WBA light flyweight crown with a 15-round decision over Joey Olivo in Taegu, Korea in 1985. A record-setting string of 17 consecutive title defenses came over the next six years. Among those he defended the belt against include Rodolfo Branco (KO 8), Willy Salazar (W 12) and two wins each over Jose DeJesus (W 15, W 12), Mario DeMarco (W 15, W 12) and Leo Gamez (W 12, W 12). Yuh’ s title reign came to and end on December 17, 1991 when Hiroki Ioka won a 12-round decision to lift the WBA strap from the Korean champion. Yuh exacted a measure of revenge with a 12-round win in the rematch on November 18, 1992 to reclaim the crown. Following a successful 12-round title defense over Yuichi Hosono in 1993, Yuh retired at the age of 29.
Considered one of the greatest fighters ever from South Korea, the 108-pound champion utilized a whirlwind style full of combinations that overwhelmed opponents and earned him the moniker “Sonagi,” which translates to rainfall. Yuh’s professional record stands at 38-1 (14 KOs).
