Kang Kyung-nam has taken a two-shot lead after the opening round of the Korea Open with just one other player carding an under-par opening round score, while Australia&aposs Kalem Richardson is in a share for eighth place. In an inconsistent first round at Woo Jeong Hills Country Club, South Korea&aposs Kang shot seven birdies and four bogeys to complete a three-under 68, while Garrett Sapp of the USA completed a 70 to take second spot on the leaderboard. Sapp birdied the eighth and 10th holes but then dropped shots on the 13th and 16th, while also managing a birdie on the 14th to sit one shot ahead of a group of five players. South Korean quartet Choi Ho-sung, Suk Jong-yul, Kim Byung-jun and Kim Dae-hyun are all tied for third with Hong Chang-kyu after scoring par in their opening rounds. In a tough day at the One Asia Tour event, a one-over 72 was enough for a share of eighth place for Richardson. Richardson is tied with Brazil&aposs Lucas Lee and another six South Koreans. Chris Campbell is a further two strokes back, while Henry Epstein is at five over.
