Not sure if it''s the pin placements, weather of a combination of both, but there have been some low scores posted from the players who went out early. Heath Slocum finished with a tournament low 6-under 65, while Hunter Mahan fired a 2-under 69. There have also been a lot of players right around par.
We will see soon if any of the leader can fire a really low score and distance themselves from the pack. But even if they do that on the front side, there is potential for very low scores on the back with three eagle holes at 13, 14, and 18.
The U.S. Open has not been won with a biridie on 18 since the late 20s, but with the 18th being reachable in two, this could be the year.
