Day takes over at the top

Jason Day has dethroned Jordan Spieth as the world number one in the latest golf rankings.

It's the second time the Australian has reached the top spot, his previous reign lasting just one week before Spieth won the Tour Championship in September.

Neither player was in action this past week, but the rankings formula determined that Day edged just ahead of Spieth with 12.42 points average to Spieth's 12.40.

Rory McIlroy maintained his third spot with 10.92 points.

Day has won six tournaments this year, including the PGA Championship in August.
