Liang Wenchong of China broke the Whistling Straits record by a stroke with a bogey-free 8-under 64. As he finished his round yesterday, Liang smiled and pumped his fist. He'd missed the cut in his only other PGA Championship appearance, and his low score this year on either the US or European Tours was a 66.
Joining Liang at 9 under were Dustin Johnson, who melted down at the US Open after being the 54-hole leader, Rory McIlroy of Northern Ireland, Bryce Molder, Martin Kaymer of Germany and Jason Day of Australia. All were still on the course.
