The U.S. Open was founded in 1881 and is held in New York City, New York. This Open is the fourth Open played in the series of the Grand Slam which is the U.S. Open, French Open, Australian Open, and Wimbledon, not in any specific order. If two players are playing and the match set is 6-6, the players MUST keep playing until one opponent wins by 2 sets. This is the only Open that enforces that rule. This year’s U.S. Open will be held from August 29th to September 11th 2016.
