Runner Knocks Ball From Catcher

[James V]

U-12 FP Softball ASA rules. I am PU. Runner on third no outs. Ground ball to F6, F6 throws a bullet to F2 who is approximately 3ft up the 3d base line. F2 has ball in glove blocking baseline awaiting the arrival of the runner.
Runner bumps F2 as F2 is applying the tag. Ball comes loose as a result of the bump, collision, (not malicious)by runner.

Is runner out or safe??
