RAFAEL NADAL KING OF TENNIS

2018 US Open SF Rafael Nadal vs. Juan Martin del Potro  6/7(3) 2/6 (Ret.)

Rafael Nadal had spent more time on the court than any other player at the US Open in 2018. To be exact, 15 hours and 54 minutes, which included his punishing five-set turnaround against Dominic Thiem in the quarterfinals. And in the end, it cost the defending champion and world No. 1. With his right knee clearly compromised, the Spaniard couldn’t withstand the onslaught of third-seeded Argentine Juan Martin del Potro, who advanced to the final, 7-6, 6-2 ret., for the first time since claiming his lone Grand Slam title in 2009.
