The Sinner v. Alcaraz era, Tiafoe's U.S. Open chances with 'Changeover' author Giri Nathan

Just as men’s tennis has been transitioning out of the “Big Three” era, a budding rivalry has begin to appear in its place that, in its infancy, has delivered much of the same thrill and fervor, as Carlos Alcaraz and Jannik Sinner have quickly infused their own dominance into the annals of the sport.

On this edition of District of Sports, George Gerbo talks with tennis writer Giri Nathan, author of the new book Changeover: A Young Rivalry and a New Era of Men's Tennis.

Nathan discusses the onus for the book, the difference between this rivalry and the one between Roger Federer, Rafael Nadal and Novak Djokovic, DMV native Frances Tiafoe’s chances for a breakthrough in this new era, and more.
