This guy serves 128 mph. Accurately. Without a grunt, groan or grimace.
You won't see any tossed racket tantrums from him. No barking at the line judge. No twitching facial freak out if he's missed a shot.
Victory or defeat, he'll patiently do an interview. In five different languages.
No excuses in defeat. No boasting in victory.
Only when he wins -- will he unwind the emotions. Like here. The yoga pose he's in here? It's called Supta Virasana - Reclined Hero's Pose.
