Thing is, an athletic girl can learn to be a good pitcher or a good catcher, sometimes both. IF THEY WANT TO.
FWIW...our HS team has 5 pitchers (2 seniors, 1 junior, 1 sophomore, 1 freshmen). 4 of them are considered "starters." They rotate until the coach finds the hottest one and rides them till their not so hot. The coach said he wants her to catch when she is not pitching. We also have 4 catchers. None of them are outstanding, but I think they would be much better than my daughter who has never caught.
Yes, she will play after high school. She has had a couple mid-major D-1 offers to pitch so far this summer.
