re: It’s interference. With visual evidence and the rule

That wasn't an easy play. The throw angle is not a clear because he has to circle the ball and it will be a tight window and a close play. Bear does catch with his LH and the runner is running right at him inside the runner path and will have avoid contact at 1st which did not happen. The rule does not discuss angles, what glove hand players have, how much experience anybody has or whether or not there was a clear path to throw.

Did the batter-runner stay inside the 3' path when a fielding play was made at 1st base? And if the batter-runner did not stay in the lane, did they leave to avoid contact with the fielder?
