South Korean golfers found themselves well out of contention after the opening round of the PGA Championship, the second major tournament of the season, with no one posting an under-par score.

When the play was suspended due to darkness at the East Course of Oak Hill Country Club in Pittsford, New York, on Thursday, four of five South Koreans in the field were tied at three-over, with only three having managed to finish their 18 holes.

Lee Kyoung-hoon finished his round at three-over 73. Lee recorded two birdies against five bogeys.

Kim Joo-hyung also carded a 73, after trading two birdies for five bogeys.

Kim Si-woo was sitting at three-over through 17 holes, with bogeys at first, seventh and 17th.

Yang Yong-eun, the 2009 PGA Championship winner, carded a 76. The 51-year-old began his day on the 10th hole and shot a one-under through his first nine, before stumbling toward the finish line with four bogeys and a double bogey over his last nine holes.

Im Sung-jae, whom some US pundits picked as a dark horse contender this week, dug himself a huge hole with a 10-over 80. He had six bogeys and two double bogeys for his worst round of the season.

Eric Cole of the United States sat at the top of the leaderboard at five-under through 14 holes. Among those who completed their first round, Bryson DeChambeau of the US had the best score at four-under 66. (Yonhap)
