Justin Thomas’ win at the SBS Tournament of Champions sees him cut his world ranking position almost in half.
The 23-year-old moves up to 12th from 22nd after a Sunday 69 was enough to see off Hideki Matsuyama and grant him his third PGA Tour victory.
Matsuyama, who added a second runner-up finish to his four wins and one fifth place finish in his last five starts, is unmoved in sixth.
The Kapalua Resort event paid dividends for veteran Pat Perez, whose tied third finish breaks him into the top 100 at 84th from 118th. Ryan Moore moves from 35th to 31st after also finishing in tied third.
Jordan Spieth joined Perez and Moore in third but finds himself unmoved in fifth, whilst fellow top tenners Dustin Johnson, third, and Patrick Reed, eighth, are also unmoved by their tied sixth finishes.
Little heard of duo William McGirt and Tony Finau, who finished tied ninth in Hawaii, jump eight places each; McGirt from 50th to 42nd and Finau up to 80th from 88th.
It was a relatively unsuccessful event for Australians Rod Pampling and Aaron Baddeley, tied 17th and tied 25th respectively, but the PGA Tour’s 2017 opener was fruitful in regards to their world rankings. The pair edge closer to the top century as Pampling moves up nine places to 119th and Baddeley up 10 to 120th.
