R1 is attempting to steal 2nd base. F2 fires a bullit to F6 covering 2B.
F6 makes a clean catch and puts the glove in front of the base as R1 slides into it.
After the dust settles, F6 still has the ball in her glove, but the EMTs are called because F6 injured her wrist. When the EMT arrives, he gingerly removes the glove and the ball falls out.
If you depend on a voluntary release to determine this call........
