The leaders are half way done with their final rounds at the 2012 Greenbrier Classic, and Webb Simpson still holds a slim lead over the field with a score of 15-under through 10 holes. Simpson has been holding steady all afternoon, as he is shooting one-under par on Sunday.
Right behind him is Troy Kelly at 14-under who has also completed 10 holes and is two-under par for the day. Daniel Summerhays finished his round at 13-under after a very impressive score of six-under on the day. He will need help, which can only come from collapses from Simpson and Kelly down the stretch.
Robert Castro shot the low round of the day so far at seven-under, however he appears to have come up short as he is sitting in the clubhouse four strokes behind the leaders.
