[1][2] A native of West Point, Pennsylvania, Stoll played softball in the local teams during her high school years, where an AAGPBL scout spotted her and decided to talk to her parents about joining the league.

[1][2] In 1947 the AAGPBL moved its spring training camp to Havana, Cuba, and Stoll was one of the two hundred girls who made the trip, this time as a member of the Grand Rapids Chicks.

[1][2][4] The AAGPBL grew to an all-time peak of ten teams in 1948, representing Eastern and Western zones; just in the first year, the circuit shifted to overhand pitching.

But the helpless Sallies finished as the worst team in the league, getting roughed up as a last-place expansion club with a 41–84 record, ending 35 and a half games behind Racine in the Western Division.

[1][2][5] When Stoll joined the Blue Sox in 1949 she took advantage of his new environment from the very beginning, raising her average to .232, while scoring 50 runs with 28 RBI in 99 games appearances.

On September 3, in the final home game of the regular season, Jean Faut of South Bend hurled a no-hitter, a 2–0 victory against the Fort Wayne Daisies, advancing her team to a tie for first place.

South Bend finished second (64-45) in the six-team league, but dissension within the Blue Sox peaked just before the season ended when infielder Pryer was disciplined following a dispute with manager Karl Winsch.

In support of Pryer, five South Bend teammates, including Mahon and Stoll, joined her in a walkout, leaving Winsch's team short-handed for the playoffs with only twelve players.

[1][12][13] Stoll saw reduced playing time in 1954, but she responded with a .302 average in just 34 games, while Kalamazoo would win the only AAGPBL Championship in five years of team history.

With the league reduced to five teams, due partly to financial problems and the difficulty of recruiting new players, the Lassies posted a fourth-place record of 48–49.

It was a neglected chapter of sports history, at least until 1992, when filmmaker Penny Marshall premiered her film A League of Their Own, which was a fictionalized account of activities in the AAGPBL.

Starring Geena Davis, Tom Hanks, Madonna, Lori Petty and Rosie O'Donnell, this film brought a rejuvenated interest to the extinct league.
