Unofficially, it's called the fifth slam. Officially, it's called the BNP Paribas Open. Informally, it's called Indian Wells. If you don't get the Tennis Channel, you might not even know it exists. But it's happening right now, out there in the desert of the Coachella Valley, and it is beautiful to look at. Indian Wells is a jewel box. It is perfect. Large but intimate stadiums, framed by the curve of distant mountains. Free Wi-Fi for the public — and free charging stations for phones. Brita filtered-water tents instead of fountain taps. Hawk-Eye for instant-replay challenges on every court. The new Stadium 2 — astonishingly, built in 10 months — has a Nobu restaurant, with a $100 minimum for a seat. This tournament is tennis as it's often parodied — tennis for billionaires! As, in fact, this is. Tournament owner Larry Ellison, the CEO and founder of Oracle, sits at no. 5 on the Forbes list of the world's billionaires.
