On the strength of his first major victory, Jimmy Walker has vaulted from 48th to 15th in the Official World Golf Ranking.
Walker once peaked as high as 10th in the world in April 2015, fresh off his fifth PGA Tour win in 18 months at the Valero Texas Open, but a winless drought thereafter saw him nearly slip outside the top 50 in the world for the first time in three years.
A testament to the strength of recent major champions, Walker at 48th in the world was the lowest ranked major champion of the last five years, dating back to 108th-ranked Keegan Bradley's PGA win at Atlantic Athletic Club in 2011. Prior to Walker, all but one of the past nine major champions has been ranked 12th or better at the time of their victory and seven of them were sixth in the world or higher.
Returning to that magic top-50 cut-off, Daniel Summerhays used a 4-under 66 Sunday to finish solo third at Baltusrol, earn his first Masters invite, and jump from 89th to 53rd in the world. He's now knocking on the door of the WGC-HSBC Champions in October.
As for changes to the top 10 this week, the top nine players stayed static, while South Africa's Branden Grace re-entered the top 10, tying to his highest career ranking.
And, just because it's been a while, after a nearly year-long absence from competitive golf, former world No. 1 Tiger Woods is down to 647th in the world, sandwiched between Canada's Roger Sloan and Italy's Alessandro Tadini, who share 645th, and Denmark's Anders Hansen at 648th. It's Woods' lowest ranking since March 1995, before his first Masters and his second of three U.S. Amateur wins.
Here's your OWGR top 10 for the week of the July 31: 1. Jason Day, 2. Dustin Johnson, 3. Jordan Spieth, 4. Rory McIlroy, 5. Henrik Stenson, 6. Bubba Watson, 7. Rickie Fowler, 8. Adam Scott, 9. Danny Willett, 10. Branden Grace.
