For the second time this year, a 32-year-old has moved to third in the world rankings on the heels of a maiden major victory.
After his win Sunday at Merion, England's Justin Rose jumped two spots to No. 3 in the latest rankings, supplanting Adam Scott, who made a similar ascension after claiming the Masters in April. The standing equals a career-best for Rose, whose U.S. Open win was the fifth PGA Tour victory of his career.
While they fell just short of the ultimate goal, both Phil Mickelson and Jason Day saw improvements in their world ranking after sharing runner-up honors at Merion. Mickelson, who has now finished second at the U.S. Open a record six times, coincidentally moved four spots to No. 6 in the world after coming up two shots short of Rose's total. Day, whose T-2 finish Sunday followed a third-place finish at Augusta earlier this season, moved up 10 spots to 16th in the world.
After a tie for fourth in his first major start as a professional, Billy Horschel continued a move up the world rankings. Last week's result was Horschel's seventh top-10 finish of 2013, and consequently the 26-year-old rose 16 spots to No. 34 in the latest standings. That's a total improvement this year of 278 spots for Horschel, who began the season at No. 312 in the world after surviving Q-School in December to earn his 2013 Tour card.
Another player making a meteoric rise through the rankings is Hideki Matsuyama, who notched a top-10 finish at Merion after turning pro just two months ago. The 21-year-old Japanese sensation, who made the cut at the Masters in both 2011 and 2012, moved up 15 spots to No. 49 after a T-10 result thanks to a 3-under 67 Sunday at Merion. Since turning pro in April, Matsuyama has two wins and two runner-up showings in Japan to go along with his first top-10 finish in a major, which will earn him a return trip to the U.S. Open at Pinehurst in 2014.
While Rose and Mickelson improved their position, the players comprising the top 10 remained otherwise unchanged: Tiger Woods and Rory McIlroy are Nos. 1 and 2, respectively, while Scott and Matt Kuchar round out the top five behind Rose. After Mickelson at sixth, Luke Donald, Brandt Snedeker, Graeme McDowell and Louis Oosthuizen make up the remainder of the top 10.
