It has been a golden summer for Rafael Nadal, winning gold in the men's doubles in the Rio Olympics along with Marc Lopez. He finishes fourth though in the singles, losing to Kei Nishikori for the bronze medal.
Then he loses out to Borna Coric in the 3rd round of the Cincy Open. However, in his side of the draw of this year's US Open, he is unsurprisingly, expected to reach the semi-final stage of his draw.
Based on the hear-to-head, his most likely opponents as he progresses in the draw are Andreas Seppi, Andrey Kuznetsov, Mikhail Kukushkin, and Gael Monfils, all very talented players.
His health and stamina are still a big question mark though even with his Rio achievements. Anyhow, this is the US Open and he has won here before and he has been known to perform well at the bigger stages, so the expectations for him remain high.
