SINGAPORE - South Korean golfer Song Young Han stormed to the top of the SMBC Singapore Open leaderboard on Friday, a day that was heavily disrupted by rain delays.
The 24-year-old fired seven birdies and an eagle for an eight-under 63 (133 total) at the Sentosa Golf Club's Serapong Course.
He leads Japan's Shintaro Kobayashi (69) by two shots at the US$1 million (S$1.44 million) event co-sanctioned by the Asian and Japanese tours.
Inclement weather had halted the afternoon session for more than two hours before it was eventually cancelled, leaving half of the 156-man field unable to complete their second rounds.
Those affected included world No. 1 Jordan Spieth (four under through six holes), 26th-ranked An Byeong Hun (seven under through seven holes) and Singapore's Quincy Quek (three under through one hole).
They will resume their rounds on Saturday morning.
The projected cut is one-over, leaving the likes of Ryder Cup star Jamie Donaldson, with scores of 72 and 77 for a seven-over 149, and 2008 champion Jeev Milkha Singh (152), set to miss the weekend play.
