Winter posted an 11–11 record in 1943, helping the Belles win both the first half of the season and AAGPBL championship. In the best-of-five Series, Racine defeated the
Kenosha Comets, winners of the second half, 3 games to 0. She also was selected for the All-Star Game, which was the first night game played at
Wrigley Field (July 1, 1943). But each year the field dimension changed as the league came closer to emulating the game played by the men's major leagues. The
pitching mound was raised, the pitching distance was lengthened, the ball shrank from season to season, the basepaths were extended and two new teams were added, until sidearm pitching was allowed in 1946. Winter had a hard time dealing with the changes as she struggled to keep mentally focused, recording a 22–45 mark between 1944 and 1945. Then she learned from a
Mexican hurler how to pitch a sidearm sling-shot delivery. In 1946, Winter earned 33 victories for only nine losses while pitching 17
shutouts with 183
strikeouts in 46
pitching appearances. Winter's 33 wins tied her with
Connie Wisniewski for most victories in a regular season. She also set all-time records of 63 consecutive scoreless innings and six consecutive shutouts; was selected an All-Star, and led Racine capture another pennant and championship. The Belles finished in first place with a league-best 74–38 record, won the semifinal round of playoffs by defeating the
South Bend Blue Sox in four games, and clinched the title after beating the 1945 AAGPBL champions
Rockford Peaches, four games to two. Throughout the playoffs
Sophie Kurys was the biggest Belles star. She led all players in
average,
stolen bases, and
runs scored. On the other hand, Winter collected four wins in all series, including three against Rockford, despite allowing 19
base runners in a 1–0 shutout victory over the Peaches in decisive Game Six. The winning run was scored by Kurys on an RBI-single by
Betty Trezza. The Belles also showed a great defense, notably by
left fielder Edythe Perlick,
right fielder Eleanor Dapkus,
first sacker Margaret Danhauser,
shortstop Trezza, and
Maddy English at
third. Winter went 22–13 with 121 strikeouts in 1947, leading her team again to the playoffs. Racine defeated the
Muskegon Lassies, three games to one, but lost to the
Grand Rapids Chicks in the final Series four games to three. Winter was able to make the adjustment to overhand pitching before the 1948 season, when
Leo Murphy, former
Pittsburgh Pirates catcher and Belles manager, helped her convert to a three-quarters delivery during
spring training. She responded by leading the league with 256 strikeouts and 329 innings while tying in victories (25) with
Alice Haylett, joining the All-Star team for a third time and helping Racine garner another pennant. The Belles lost the semifinal playoff to the Peaches, the eventually winners of the Championship Title. Winter moved back to Arizona in the late 1960s and Sophie Kurys lived across the street from her home in Scottsdale, Arizona, until after Winter's death in 1996. ==Pitching statistics==
