1970 US Open (tennis)


The 1970 US Open was a tennis tournament that took place on the outdoor grass courts at the West Side Tennis Club in Forest Hills, Queens, in New York, United States. The tournament ran from 2 September until 13 September. It was the 90th staging of the US Open, and the fourth Grand Slam tennis event of 1970.
It was the first Grand Slam tournament in which the tiebreak was used to decide the set at a 6-6 score. It differed from the current tie-break scoring in that it was won by the first player to reach five points with a sudden death at 4-4. A red flag would be put up by the umpire’s seat to draw fan attention to the tiebreaker in progress. Most players disapproved of the tiebreaker but the visitors loved it.
