With Spieth jumping four spots, Jim Furyk dropped one from six to seven. While Sergio Garcia held steady at No. 8, WGC-Cadillac Championship winner Dustin Johnson fell two to No. 9 and Justin Rose dropped one spot to No. 10.

Rickie Fowler, Martin Kaymer, Jimmy Walker and Matt Kuchar all remained Nos. 11-14 and Reed improved one to No. 15. Reed traded spots with Hideki Matsuyama, who fell to 16.

Billy Horschel and Brooks Koepka stayed put at 17 and 18, while Victor Dubuisson and J.B. Holmes swapped places, with Dubuisson up one to 19 and Holmes down to 20.

With his tie for second at the Valspar Championship, O'Hair made a huge move up the rankings. He improved 213 spots from No. 401 to No. 188.
