Tiger Woods holds the record for the lowest single-season scoring average on the PGA Tour. In 2000, his unadjusted average was 68.17 strokes per round, while his adjusted average was 67.794.
The 2000 season was one of golf’s most dominant campaigns. Woods won nine PGA Tour events, including three major championships: the U.S. Open, The Open Championship and the PGA Championship. His actual average broke Byron Nelson’s 1945 mark of 68.33, a record that had stood for 55 years.
A common mix-up is the difference between actual and adjusted scoring average. Actual scoring average is the strokes a player takes per round; adjusted scoring accounts for the difficulty of the courses and fields. Woods holds the historical low under both measures, making the answer the same either way.
