Williams' parents wanted their daughter to wait until she was 16 to participate in professional tournaments.  However, in 1995 just after turning 14, Williams planned to make her professional debut as a wild-card entry in the Bank of the West Classic in Oakland, California , but was denied by the WTA due to age-eligibility restrictions of the organization.  She subsequently filed an antitrust lawsuit against the women's tour, but withdrew it at the behest of her parents.  Her first professional event was in October 1995 at the Bell Challenge in Quebec ,   where she used a wild-card entry to circumvent age-eligibility rules.  She lost in the first round of qualifying to then 18-year-old American Annie Miller , winning just two games.
