Betsy "Sockum" Jochum (born February 8, 1921) is a former outfielder and pitcher who played from 1943 through 1948 in the All-American Girls Professional Baseball League.

[1] A native of Cincinnati, Jochum was one of the sixty original founding members of the All-American Girls Professional Baseball League.

An ideal leadoff hitter, she was one of the fastest runners in the early years of the league and rarely struck out, fanning only 104 times in 2,401 plate appearances, which combined with a stellar defense and a strong and secure throwing arm.

The girls were placed on the rosters of four fifteen-player teams: Kenosha Comets, Racine Belles, Rockford Peaches and South Bend Blue Sox.

[3][4] Betsy was the daughter of Frank and Katherine Jochum, German-speaking Hungarians who immigrated to United States, landed at Ellis Island, and eventually arrived to Cincinnati, just before the World War began in 1917.

During her student years at Hughes Center High School, she took part in many intramural athletic events offered for girls: basketball, volleyball, track and field and softball.

[2] Jochum entered the league in 1943 and spent her entire six-year career with the South Bend Blue Sox, one of two teams to play in every AAGPBL season, the other being the Rockford Peaches.

Jochum appeared at center field and left, pitched, and also played first base for a long time when the regular was hurt.

For the second consecutive year South Bend made the playoffs, but again lost in the first round, this time to the Grand Rapids Chicks, who defeated the Racine Belles in seven games.

When she was not pitching, South Bend manager Marty McManus used her to fill at outfield, first base and pinch hit, even though she batted a low-career .195 average.

Nevertheless, Jochum provided 14 of the 57 victories of her team, including a sparkling 1.51 earned run average, and striking out 103 batters while walking just 58 in 215 innings of work.

[14] After her baseball days, Jochum earned bachelor's and master's degrees in physical education from Illinois State University.
