(Reuters) - Top golfers needed to pick up their games to keep pace with Dustin Johnson, Australian Jason Day said on Sunday after losing top ranking to the long-hitting American.
After 47 consecutive weeks at the top, Day ceded his position when Johnson won the Genesis Open in southern California on Sunday.
Johnson had knocked on the door before, spending much of 2016 in second position, before making another push at the start of 2017 and finally passing Day.
"Whatever he's doing, he just needs to keep doing it," Day told reporters after finishing a distant equal 64th at Riviera.
