Is this interference? Thanks.

Interference by a BR is covered under 8-2-E thru H. There is nothing there that talks of interfering with a loose ball except for a dropped third strike, when the batter-runner is liable to be put out. This was a walk, so she is awarded first base; there's no possibility to make a play on her going to first.

OP: "causes the catcher another split second to recover the ball and her throw to 3rd is late, runner is safe"
