Sell is aware that his time as an active professional player is limited — Pete Sampras retired at 32, Andre Agassi at 36 — and he’s leveraging his skills to ensure he can transition smoothly into a post-tour career after his body breaks down or he tires of the grind.

Another factor in his atypical career has been the thriving Southern California tennis community, which has nurtured generations of stars from Sampras to the Williams sisters.
