Late start today, they will be playing on Monday. What amazes me with this scoring is not that Barnes is just -8, he is -8 on a 7400 yard par 70 course. In all fairness, with 500+ yard par 4's (although not all were set at 500+), this should be a par 72, if that was the case, he would be -12 after 36, that is redonkulous for U.S. Open golf.
Personally, I don't see HIM keeping this place, especially having all this time to <think> about "being the leader of the U.S. Open after 36 holes", but with the course continuing to play soft, most any of the other "names" that are under par have a serious chance. Monday will be every exciting. Not only would Tiger have to play perfect "Tiger Golf", which he can, but there are 30+ other people in front of him which would all have to play mediocre golf on a course that is playing easier than harder, which is unlikely.
