 This was also the first time the men's singles champion at the US Open won the title after being match point down since Andy Roddick in 2003, with Djokovic saving two match points against Roger Federer in the semifinals.Remarkably, this was the second consecutive US Open where Djokovic saved two match points against Federer en route to the final and fifth consecutive US Open that Djokovic and Federer played each other.With his semi-final loss, Federer failed to win a grand slam in a calendar year for the first time since 2002.
