On the second episode of Three, Joel, Amy and Gill discuss the largest mystery heading into the 2020 ATP restart. Will Rafael Nadal play the US Open? Many factors are at play, including his history of hard court injury and what it means to miss a major. We discuss the history of slam skippage and career longevity, using Andre Agassi as a case study. Then, we bring the conversation over to Roger Federer and Novak Djokovic, who have had healthier careers than Nadal, but still have had their fair share of injuries.
