Sunday's U.S. Open final will feature two resurgent superstars: Juan Martin del Potro and Novak Djokovic.
Del Potro is back in a Grand Slam final for the first time since he won his lone major at this tournament in 2009. Since then, he's undergone two wrist surgeries and was contemplating quitting tennis in 2015.
Djokovic missed this tournament last year due to an elbow injury that eventually required surgery. The Serbian came back to win Wimbledon in July and is seeking his 14th Grand Slam title, which would tie Pete Sampras for third all-time.
The stage is set for a fantastic spectacle on Arthur Ashe.
