Jordan Spieth was already No. 1 in the Official World Golf Ranking, but he managed to increase his lead at the top following an eight-shot romp at the Hyundai Tournament of Champions.
Spieth became just the second player ever to reach the 30 under plateau in a 72-hole PGA Tour event, earning his seventh career Tour victory and sixth in the last 10 months.
Spieth's OWGR average is now 12.14, which is 1.4 points ahead of Jason Day who remains in second. To put that gap in perspective, that is the same margin that currently separates world No. 11 Adam Scott and No. 28 Martin Kaymer.
After the winners-only event in Maui, the only change to the OWGR top 10 saw Rickie Fowler jump one spot from sixth to fifth, supplanting the idle Henrik Stenson. Other changes further down the standings included Zach Johnson, Brooks Koepka and Kevin Kisner, who all moved up one position to Nos. 12, 14 and 16, respectively.
Brandt Snedeker made a big move, jumping from No. 50 to No. 34 after his T-3 finish at Kapalua, while Padraig Harrington and Peter Malnati both rose after T-6 finishes. Harrington is up 21 spots to No. 120, while Malnati rose 31 spots to No. 145.
After capturing the first European Tour event of the year in South Africa, 22-year-old Brandon Stone jumped from No. 249 to No. 118.
The top 10 now includes Spieth, Day, Rory McIlroy, Bubba Watson, Fowler, Stenson, Justin Rose, Dustin Johnson, Jim Furyk and Patrick Reed.
Out of action since August because of a back injury, Tiger Woods dropped seven spots to No. 420 in the standings.
