It was his first US Open title and fourth major title overall. Djokovic saved match points en route to the title, saving two against Roger Federer in the semifinals. This was the second consecutive US Open where Djokovic saved two match points against Federer to reach the final, and the fifth consecutive US Open where Djokovic and Federer played each other. With the loss, Federer failed to win a major in a calendar year for the first time since 2002.
