PHILADELPHIA -- Rory McIlroy claimed his first major championship title in record fashion on Sunday at the U.S. Open and the victory helped him jump four spots to No. 4 in the world rankings.
That is the highest the 22-year-old has been ranked in his career.
With the added points available at the season's second major, 14 of the top 20 places in the world rankings changed hands this week.
That being said, the top three remained the same with Luke Donald followed by Lee Westwood and Martin Kaymer. McIlroy's move knocked the next four players down one spot apiece.
Steve Stricker was down one to No. 5, while Phil Mickelson, Matt Kuchar and Graeme McDowell also dipped a notch.
Jason Day posted his second straight runner-up finish in a major, and third straight top-10 in a major, and jumped nine spots to No. 9. That is also a career-high ranking for him.
Masters winner Charl Schwartzel inched up one to 10th, while Dustin Johnson and Paul Casey both fell two places apiece to 11th and 12th respectively.
Bubba Watson was down one to 13 and Ian Poulter and Nick Watney also slipped one spot. K.J. Choi held steady at No. 16.
Tiger Woods missed the U.S. Open due to injury and slid two places to No. 17 and Robert Karlsson fell one to 18. Jim Furyk and Hunter Mahan remained 19th and 20th this week.
