SEOUL, June 7 (Reuters) - Yang Sang-min's own goal 11 minutes from time consigned Suwon Bluewings to a 1-0 home defeat by 10-man Gwangju FC in South Korea's top flight on Sunday as they missed the chance to close the gap on leaders Jeonbuk Motors.
Jeong Jun-Yeon was sent off for a second yellow card offence in the 71st minute but the visitors got the all-important goal when the ball went in off 31-year-old defender Yang.
The defeat meant Suwon stayed second, eight points behind Jeonbuk on 24, having played a match less than the K-League Classic leaders.
