Fothergill's career peaked in 1968 and 1969, when she won seven PWBA titles, four of them majors. At ages 23 and 24, she was named woman
Bowler of the Year in consecutive years by the Bowling Writers' Association of America (BWAA). In 1968, she became the first woman bowler to win more than $10,000 in one season. A 1969 profile on Fothergill noted that, despite her tiny frame (, ), she was able to throw a ball with power and accuracy. The author compared her approach to "a hungry wolf after a lamb chop." • May 1968 – She won the Women's BPAA All-Star championship (later renamed the
U.S. Women's Open) in
Garden City, New York. She was the first woman to win in her first All-Star appearance and the first left-hander in the men's or women's division to claim an All-Star championship. Her average of 211.11 in 36 games was just short of the record of 211.47 set by Marion Ladewig in 1951. • August 1968 – She won the
PWBA Championship tournament in
Flint, Michigan, taking home $3,000 in prize money. • May 1969 – For the second consecutive year, she won the BPAA All-Star championship held at Hialeah Lanes in Florida, becoming the first player to successfully defend her crown in this event since
Marion Ladewig in 1954. • August 1969 - Fothergill repeated as winner at the PWBA Championship. She outscored Ethel Glasco, 208-192, in the title match to become the first woman to win the championship in consecutive years. It was her sixth PWBA title in her three-year career to that point. ==Lawsuit to compete in men's tournaments==
