A tennis pro, let alone one of the best tennis stars to ever play the game, can certainly do that. I practiced a lot back in the day, and during practice, coaches would set up a pyramid of tennis balls in different positions in or around the respective service box. The objective was to hit the targets with 1st service-quality serves. If you hit the targets, you get to go on water break, if not, you'd have to run a set of lines. Again, someone of Federer's level of skill, would definitely be able to something like this repeatedly. I'm sure he'd miss, but wouldn't be too far off.im still believing this is fake
