Juan Martin Del Potro is the first US Open finalist!
Nadal was forced to leave the game after two sets with Del Potro, who will return to the final of the US Open after 9 years, for his second final in a Grand Slam event!
For about 90 minutes, we saw a nice match at Arthur Ashe Stadium, with Del Potro trying to dominate and do it in most cases.
In the second set, Nadal seemed to be unable to follow the rhythm due to the discomfort he felt on his right knee. He took a medical timetable but could not continue the game. He accepted 2 break and just lost the second set with 6-2, after 2 hours of total fight, picked up a white towel and exchanged handshakes.
In the final of Sunday 23:00, Del Potro will face one of Novak Djokovic and Kei Nishikori.
