Recent findings (audit lane, verbatim)

Andre Agassi — The entry states Agassi finished 1999 as the year-end top player, but the ATP year-end No. 1 for 1999 was Pete Sampras.

Andre Agassi — The entry states Agassi won the 1990 ATP Tour World Championships, but he never won that tournament; his best result was runner-up in 1990, 1995, and 2000.

Arantxa Sánchez Vicario — The entry states she won the US Open in 1993 in women's doubles, but she actually won the US Open women's doubles title in 1994 (with Jana Novotná), not 1993.

Arantxa Sánchez Vicario — The entry states she was the first Spanish woman inducted into the International Tennis Hall of Fame, but Lili Álvarez was inducted in 1996, making Álvarez the first Spanish woman inductee, not Sánchez Vicario.

Arthur Ashe — The entry states 'After retiring in 1980, Ashe underwent heart bypass surgery in 1979', which is a chronological error; the surgery occurred in 1979, before his retirement in 1980.

Arthur Ashe — The entry states 'He was posthumously awarded the Presidential Medal of Freedom by President Bill Clinton on June 20, 1993', but the medal was presented on August 9, 1993, not June 20.

Bill Tilden — Tilden won the U.S. Pro title in 1931, 1932, 1933, 1934, and 1935 — this is incorrect; he won the U.S. Pro title in 1931, 1932, 1933, 1934, and 1936 (not 1935; he lost the 1935 final to George Lott).

Billie Jean King — The entry states King completed her history degree in May 2026 as a past event, but this is a future date and not a historical fact.

Billie Jean King — The entry says she was named one of Time’s Persons of the Year in 1975; she was actually named one of Time's Women of the Year in 1975.
