Maria Sharapova continues her headline-winning ways even as she remains far from competitive tennis play. On the heels of her entrance into a fast-track Harvard Business School certification program and London appearances away from Wimbledon, the Russian's latest professional escapade saw her serve as an NBA intern during a three-day course.

A spokesperson for that North America-bound professional basketball league described Sharapova as "very smart" and "incredibly inquisitive."

Sharapova is serving a two-year ban from the WTA Tour as a result of testing positive for meldonium. The substance is suspected as a performance-enhancing drug, though it has been determined she did not take it with the intention of getting "a leg up" on the competition.

As written in the Washington Post, "Coincidentally, [the New York Post's] Mark Berman reports that the NBA will add meldonium to its banned-substance list in time for the coming season."
