2016 U.S. Open Days 1 & 2
On the men's side, Novak Djokovic will look to defend his title after a disappointing upset at Wimbledon and a loss to Juan Marin del Potro in the Olympics, while Flavia Pennetta, the first Italian to ever win the U.S. Open, will look to defend the women's title.
Serena Williams is the odds-on favorite to win the U.S. Open last year. The number one-ranked player in the world lost a stunner to Roberta Vinci in the semifinals of the 2015 U.S. Open.
Other favorites on the men's side include Andy Murray and del Potro.
The festivities officially got underway with the annual Arthur Ashe Kid's Day at the USTA's Billie Jean King National Tennis Center in Flushing Meadows Park.
In addition to the many activities on the grounds on Saturday, there were also performances by Flo Rida, Zara Larsson and Laura Marano to name a few.
On opening night Monday, Phil Collins came out of retirement to perform with Hamilton star Leslie Odom, Jr. The pair performed a duet of “Easy Lover” and Collins played his hit “In The Air Tonight.”
