The American tennis player Andy Roddick puts some weight behind his serve.
According to the video comments over at YouTube, this clip has been used for a Powerade commercial but someone also points out that "it happened in front of a stadium full of people, it's not fake".
Well, if it happened in front of a bunch of people, it must be real.
Look at all the Criss Angel tricks. Nobody would say THEY aren't real.
If you want to get picky, the shots with the audience could be real, but the actual pictures of the ball don't even show any faces in the same shot. But they wouldn't edit that, would they?
While a ball getting stuck in the ground like that is quite improbable. It can certainly break someone's face. John Isner hit a serve and it hit my friend in the face, and broke her brow-bone.
But it's still cool. A nice idea. And the commentators did a great job of acting with their voices to sell it. The CG looked half decent too.
