On Thursday, defending French Open doubles champions Lucie Safarova and Bethanie Mattek-Sands take the court to start their bid for a third Grand Slam title as a duo. Standing in their way? None other than the World No.1s Sania Mirza and Martina Hingis – who are just five wins away from a ‘SanTina Slam’ – and a stacked draw filled with dangerous teams.

Ahead of their doubles opener, the pair sat down with CNN Open Court to discuss the origins of “Team Bucie,” their on-court chemistry, and Safarova’s return from a career-threatening illness.
