Maria Sharapova withdrew from the U.S. Open on Sunday night, but not without making her presence in New York known, virtually and in person.

ThePostGame already showed you how to play tennis against Sharapova in virtual reality. Sharapova also made a stop in Flushing Meadows in the form of a hologram.

Maria Sharapova Hologram

Sharapova did her best Tupac impression at American Express's "Rally on the River" last Wednesday. The event featured top-ranked American John Isner, Puerto Rican youngster Monica Puig and comedian/actor Kevin James playing tennis, a DJ set from Chromeo, hydro-interactive tennis and the chance for fans to throw and hit tennis balls into the Hudson River (there was a net).

There was also a hologram of Sharapova over the river, along with images of her tennis idols.

The 28-year-old Russian made an appearance, although she did not play. She was in New York hoping to play in the U.S. Open, which she won in 2006, but has been sidelined with a leg injury since Wimbledon.

In the meantime, Isner ran James around the court. The King of Queens is no king of the tennis court.
