Colonial Country Club, the site of this week’s Charles Schwab Challenge, historically has been known as a ballstrikers’ paradise. It has small greens and narrow fairways, and the Texas wind can push and shove a player’s shot offline.
Last season Kevin Na won after finishing first in the field in strokes gained approach the green with a four-day total of 8.3. Strokes gained approach the green measures how much of an advantage a golfer has over the field on shots hit from the fairway. Na’s total represents more than an eight-shot edge over the average player through 72 holes.
The 2018 winner at Colonial, Justin Rose, also finished first in strokes gained approach that year with a total of 10.2.
