San Francisco: Dustin Johnson or Hideki Matsuyama can reach the top of the world rankings for the first time this week, but current number one Jason Day is determined to prevent that from happening.
US Open champion Johnson needs to win the Genesis Open and for Day to finish worse than a three-way tie for third to claim top spot at Riviera Country Club. A sixth win in his last 10 worldwide events will make Matsuyama the first male Japanese player to become World No. 1, but only if Day finishes lower than a two-way tie for 24th.
"They don't give trophies for it, it is more of a pride thing at the end of your career; you want to know how many weeks you were at number one," Day, who was fifth in last week's AT&T Pebble Beach Pro-Am, told a pre-tournament press conference.
