1st Base

[Stair-Climber]

NFHS Question:
B1 hits to the infield. Ball is fielded and throw goes to 1st base. F3 has one foot in the middle of 1st base bag (no double bag in Indiana), covering much of the bag's surface, waiting for the throw. Throw to F3 just beats B1 to 1st base for the out. As B1 arrives to the 1st base bag, she runs into F3 who is still covering much of the bag's surface with her foot. As B1 runs into F3, B1 gets knocked away from the bag and never even touches it. That out ended the half-inning. B1's coach comes over and politely questions me about F3 covering much of the bag with her foot, thus not allowing B1 to even reach the bag. I told the coach that because a play was being made on B1 at 1st base, I didn't know of any rule that would require F3 to only touch the side of the bag or any certain portion of the bag. In other words, I told the coach that F3 had the right to step on any part of the bag as long as a play was being made at 1st base. My question: Was I correct in my ruling? If not, is there a rule somewhere that describes where the defensive player, who is covering 1st base and taking the throw to 1st base, must place her foot on the bag?
