Rory McIlroy and Roger Federer hang out at ATP event in Cincinnati

Being the top-ranked golfer in the world comes with some pretty nice perks. Marquee pairings, invites to play exhibition matches in China, and biscuits with your likeness on them are just a few of the highlights.

Another highlight? How about hanging out with another No. 1 -- that, of course, being Roger Federer, who moved back to the top in the tennis world following his incredible win at Wimbledon.

With Carolina Wozniacki, also known as the other half of "Wozzllroy," playing a joint WTA/ATP event in Cincinnati this week, the two-time major winner decided to spend his time before the Barclays hanging around the event. (Side note: He also apparently took time out to help Novak Djokovic with his golf swing.)

As you'd expect following his second eight-shot major win, McIlroy was all smile for this photo with Federer, who has a staggering 17 Grand Slam titles on the tennis court, a figure the 23-year-old Ulsterman will have a hard time matching on the course. But if he keeps winning majors by eight shots, hey, you never know!

McIlroy showed up to the tennis tournament wearing his Sunday red, after he took a page from Tiger Woods' book and decided to sport a red shirt during the final round of the PGA Championship.

Federer also decided to don a red shirt for the photo, which makes you wonder if it's the color of champions. Tiger, Federer, Rory. That may be a stretch, but after taking a look at McIlroy and Federer, I may start wearing red to my weekly money game if it'll give me good luck.
