Jeanne Evert Dubin, a former world-ranked professional tennis player and a younger sister of the 18-time Grand Slam champion Chris Evert, died on Thursday. She was 62.

The cause was ovarian cancer, according to an obituary posted online by Lorne & Sons Funeral Home in Delray Beach, Fla., which is handling her funeral arrangements.

One of five tennis-playing children raised by the teaching pro Jimmy Evert and his wife, Colette Evert, Jeanne had a standout junior career in which she became the nation’s top-ranked player in her age group. She turned pro in 1973 at age 15, after beating the established stars Rosie Casals and the top-ranked Margaret Court.

She was the youngest player that year to represent her country in the Wightman Cup, an annual competition between British and American players that was discontinued in 1989. And she didn’t lose a match in helping a United States team reach the Fed Cup final in 1974.
