There are no women in Major League Baseball yet there are in Minor League Baseball.
I do not believe that there are, or ever have been, female players in Minor League Baseball*. There were some women who were drafted, but none of them every signed or played.

* By “Minor League Baseball” I mean those leagues that are a part of the minor leagues affiliated with Major League Baseball. Of course, there were professional independent leagues where women played and there may be an independent professional team here or there that has a woman on it.
