As of 8 January 2018, he has been the No. 1-ranked golfer for 47 consecutive weeks, which is the 9th longest streak in PGA Tour history.
He won the 2016 U.S. Open at Oakmont Country Club with a 4-under-par score of 276 for his first major championship. He had previously finished in a tie for second at both the 2011 Open Championship and the 2015 U.S. Open. He also has five World Golf Championships victories, with only Tiger Woods having won more, and he is the first player to win each of the four World Golf Championship events. He is one of the longest drivers on the PGA Tour, having been ranked in the top five annually from 2008 and leading in 2015. By virtue of his 2018 Sentry Tournament of Champions win, Johnson became only the third player in Tour history to win a Tour title in each of his first 11 seasons, joining Jack Nicklaus (17) and Tiger Woods (14).
