Jean Balukas
Balukas won the U.S. Open seven years in a row, from 1972 through 1978. She won six world championship titles. She had over 100 professional competition first-place finishes; 38 of those wins were in major events. She had a streak of 16 first-place finishes in women's professional tournaments. Balukas was also the only woman to compete equally with men in professional play in her era. She quit the sport in 1988 because of a dispute that happened in a match at the World Open Nine-ball Championship that year.
