Focus on the par 4s
Perhaps somewhat related to not needing as much distance, winners of the British Open are much more likely to play the par 4s better than the par 5s. Whereas such an important part of, say, the Masters is taking advantage of the par 5s, at the Open, 12 of the past 19 (that's as far back as the stat goes) winners ranked higher that week on the par 4s. All 19 ranked in the top 10, with 11 ranking either first or second in the category. In 2012, Ernie Els made what turned out to be the winning birdie putt on the par-4 18th (left) and played the par 4s at Royal Lytham two shots better than anyone else in the field.
