Johnson, who had been third in the world rankings, takes over top spot from Australian Jason Day, who had held the honour for 47 consecutive weeks. US Open champion Johnson needed to win the tournament and see Day finish worse than a tie for third to claim the No 1 ranking. Johnson is the 20th player to hold top spot since the inception of the rankings in 1986.
