Jason Day surged to a career-best No. 4 in the world after winning the RBC Canadian Open on Sunday. He was eighth a week ago.
Day broke up the American bloc of No. 2 Jordan Spieth, No. 3 Bubba Watson, new No. 5 Dustin Johnson and No. 6 Jim Furyk.
Sliding the opposite way were Justin Rose (5th to 7th), Rickie Fowler (6th to 8th) and Henrik Stenson (8th to 9th). Stenson has slid seven spots since ending 2014 at No. 2 in the world. Stenson is trying to avoid becoming the third player from last year’s Top 5 to fall into double digits, joining Sergio Garcia (No. 10 down from No. 5) and Adam Scott (No. 11 down from No. 3).
Omega European Masters champion Danny Willett rose from 32nd to 24th as a result. He’s climbed 26 spots since the end of 2014. Runner-up Matthew Fitzpatrick made the real leap, from 214th to 121st. With three top 10 finishes this year, Fitzpatrick has risen almost 300 spots since the start of 2015.
And yes, the idle Tiger Woods took another dip in the rankings, dropping eight spots to No. 266 from No. 258.
