Olga Zaitseva (born 12 March 1962) is a former competitor for the Soviet Union at the 1979, 1980, 1981 and 1983 editions of the Federation Cup.
 Despite posting doubles victories over top professionals such as Betty Stöve, Hana Mandlíková and Renáta Tomanová, Zaitseva did not compete at any point on the women's professional tennis circuit or at any of the Grand Slams and thus never attained a world ranking.
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, 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.
 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.

The Arthur Ashe Courage Award (sometimes called the Arthur Ashe Award for Courage or Arthur Ashe for Courage Award) is an award that is part of the ESPY awards.
 Although it is a sport-oriented award, it is not limited to sports-related people or actions, as it is presented annually to individuals whose contributions "transcend sports".
 Often these figures are also athletes who have been at the top of their sport, such as Muhammad Ali, Dean Smith, and Cathy Freeman.
Betsy Nagelsen and Renáta Tomanová were the defending champions.
