With the West Coast Swing complete and most members of the PGA Tour having played at least three or four tournaments this season, statistics can start to be more meaningful.
One of the most important stats related to winning is strokes gained approach the green. It measures how well a golfer performs on shots hit from beyond 30 yards of the green that are not tee shots. Players who rank highly tend to create more birdie chances and avoid carding big, round-busting scores.
