The US Open begins today, and will last through September 8th. That's a pretty decent chunk of time for one sport to dominate your TV screen (um, longer than New York Fashion Week), especially when we're still recovering from this summer's never-ending, but seriously entertaining World Cup. It's kind of a bummer if you aren't a tennis fan, so we came up with 12 reasons why you should be -- more specifically, they're the 12 hottest guys, in our humble opinion, playing tennis at the US Open this year.

We're sure Roger Federer rings a bell, but if you haven't heard of John Isner (Go USA!), Guillermo Garcia-Lopez, or Julien Benneteau, you can thank us later. In the meantime, click through the gallery to see all the eye candy from the US Open. We're willing to bet you're a tennis convert by the end of it.
