I give it to the 2nd baseman. It was her ball and she should have taken charge. Then, I take out my pink sticky notes and I write something angrily and stick it to the scorebook.
An error could be charged to the pitcher if she knocked the ball loose.If you give an error it would have to be 2B. The question is should 2nd have caught the ball. If she dove at the last second and dropped it it would be a hit, but if she just dropped it it's an error. Even if P should have caught it , no error on P (remember it's always the fielders fault
