Collision at 1B

[Dakota]

Lower skilled teams. I was watching the game. USA rules.

Batter hits an infield ground ball.

F3 is set up for some reason off 1B toward home straddling the foul line.

Throw to F3 arrives before the runner arrives, and F3 clearly has possession of the ball before BR arrives.

But since F3 is off the bag (and partially in foul territory) she attempts to reach back with her leg to find 1B with her foot, but is finding the orange bag, not white.

BR arrives before F3 manages to touch the white bag. BR, running toward the bag, remains upright and collides squarely with F3, knocking her down. BR then touches the orange bag.

There is no attempt at a tag, and there is no indication of malicious intent on the part of the BR.

Call?
