2013 - Tiger Woods shoots 65 on the North Course (7-under) and wins by 4 shots. He was 7 under for the three rounds at the South Course. Brandt Snedeker shot 65 on the North Course and finished second at 10 under).
2012 - Snedeker won with at 64 on the North Course, which was half of his sub-par totals for the tournament and Kyle Stanley was 10 under on the North before his ultimate demise on the 18th at the South.
2011 - Bubba threw down a 65 on his way to a 16 under victory. That year Mickelson only shot a 69 on the North and lost by a stroke.
So, the precedent is set. Whoever does not go low on the less heralded North course will not go home a winner.
