What do we have?

[MT 73]

ASA
B level varsity.
Batter hits shot into center and is going for second.
F6 is straddling the bag and when she is about to catch the throw from the centerfielder the BR goes into the base standing up and they collide, which causes the throw to go wide and allows the BR to advance to 3B.
Coach wants me (PU) to call interference but my partner says nothing so I do not not get involved.
Was there any violation here or just a train wreck?
