London, Aug 10 (ANI): American golfer Jason Dufner has hit a course-record 63 to grab a two-shot halfway lead in the US PGA but missed out on the lowest round in Major history.
According to the BBC, the 2001 runner-up led Adam Scott, Matt Kuchar and Jim Furyk.
US Open champion Justin Rose shot 66 to end six under but Tiger Woods and Rory McIlroy endured difficult days, the report said.
World number one Woods was unable to recreate the spark that yielded a fifth title of the year on Sunday and hit a level-par 70 to end one over and defending champion McIlroy was in danger of missing a second straight cut at a major after slipping to four over for the tournament through 10 holes during the worst of a morning deluge, the report added.
Lee Westwood, who was tied second overnight, also dropped back with a three-over 73 to leave him one under, the report further said.
Dufner said that he showed a little bit of nerves but was glad to enter the history books. (ANI)
