[Scooby]

I had this today in a high school game. B1 swing and hits a dribbler. She is safe at first and runs through the bag. She returns to the bag and continues toward home (1 or 2 steps) when the 1st base coach grabs her arm and guides her back to first. (I did call her out)
1. Is there rule support to have her out?
2. Would you call her out?
