The 1968 US Open (formerly known as U.S. National Championships) was a tennis tournament that took place on the outdoor grass courts at the West Side Tennis Club, Forest Hills in New York City, United States. The tournament ran from 29 August until 8 September. It was the 88th staging of the tournament and the fourth Grand Slam event of 1968. It was the first edition of the tournament in the Open Era of tennis and as such for the first time offered prize money, totaling $100,000. Arthur Ashe and Virginia Wade won the singles titles. Ashe was still registered as an amateur and therefore not entitled to the $14,000 first-prize money, which instead went to runner-up Tom Okker, while Wade earned $6,000.[3] Frank Parker, at the age of 52, lost to eventual champion Arthur Ashe in the second round, and still holds the record for the oldest man to compete in a Grand Slam singles tournament.
