Brooks Koepka is in the clubhouse at 12 under after posting the lowest 36-hole score in major championship history while leading the field by seven strokes.
No golfer in history had previously led a major by more than six strokes through the first two rounds.
While Koepka dominated Tiger Woods fell apart. He finished 5 over through his 36 holes, a stunning 17 back of Koepka and below the cut line for the tournament.
Jordan Spieth and Dustin Johnson are attempting to give Koepka a run for his money, but it would take Koepka falling off in a major way on Saturday to put either in true contention.
