Interference or Nothing?

[Dakota]

My first reaction was no call, like the others here, but as stated, she is a BR, not a batter. We do have this rule:

8-2-F-2

BATTER-RUNNER IS OUT
When the batter-runner interferes with a fielder attempting to throw the ball,

Notice... "interferes with a fielder attempting to throw".

Was the catcher attempting to throw? As stated, yes. Did the BR interfere? As stated, yes. If you're looking for a definitive act of interference, she stepped back and then forward, she didn't just move forward toward 1B.
