Justin Thomas once said he never thought much about being No. 1 in the world ranking until he no longer had it. Brooks Koepka also has a different outlook. He says he cared too much about it when he first got to the top and was consumed by trying to stay there.
Koepka first reached No. 1 by winning the CJ Cup in South Korea. He stayed two weeks, alternated with Justin Rose the next three weeks, ended the year at the top, watched Dustin Johnson and Rose battle for No. 1 for more than four months, and then reclaimed it with his PGA Championship victory.
