In 1987, women’s tennis was transformed as Steffi Graf dethroned legends, seized the No. 1 ranking, and ignited a fierce season-long debate: Does greatness mean dominating all year, or winning the biggest titles? As Martina Navratilova fights to defend her crown, a generational showdown unfolds—culminating in one of the sport’s most dramatic years and the ultimate question: Who really deserves to be number one?

In Paris, 1987, Steffi Graf arrives as the rising No. 2 seed—crushing early rounds, surviving a tense semifinal with Gabriela Sabatini, and stepping into a final that feels like a referendum on the sport’s future. Across the net is Martina Navratilova, the reigning No. 1, brilliant but visibly under pressure to hold off the new era. In the deciding set, Martina surges to a lead and serves for the championship—only for the match to swing on free points, nerves, and a closing stretch where Graf stays steady and capitalizes. The result is a French Open final that doesn’t just crown a champion—it signals a changing of the guard.

In March 1987, tennis fans are introduced to 13-year-old Monica Seles not through match footage, but through a hype machine. Nick Bollettieri brands her “the Baltic Basher,” calls her the best young player he’s ever seen, and frames her family’s ambition as singular: nothing less than No. 1. In this episode we learn the truth about Monica's first few months at the Bollettieri Academy, the price she paid for a tennis education that seemed too good to be true, and the Seles family that rallied not to make Monica No. 1, but to make her happy.
