Katherine Ann Heim (later McDaniel; August 21, 1917 – May 11, 2015) was a Canadian catcher who played in the All-American Girls Professional Baseball League.

[2] While she was a light-hitting catcher, Heim highlighted as a defensive specialist with good pitch-calling skills and possessed a strong, accurate throwing arm.

She helped the Kenosha Comets win the pennant title the first year, though the team lost to the Racine Belles in the best-of-five Championship Round.

[4] In 1992, Heim, along with Jean Havlish and Nancy Mudge, two other Minnesota residents and former AAGPBL players, were invited to throw out the first pitch in a game Angels-Twins played at the Metrodome.

The trio also was honored by the Colorado Silver Bullets all-female baseball team in their 1994 inaugural season, in which they threw out the first ball pitch of a game celebrated in Saint Paul.
