Is the runner out if the runner and fielder incidentally collide?

Answer 1

if the fielder is a) in the baseline, and b) doesn't have the ball, then no.

If the runner goes out of the baseline to strike the fielder, he is out for leaving the baseline.

If the fielder has the ball, and as a result of the collision he tags the runner, then runner is out.

If the fielder has the ball and is trying to tag the runner, but the collision knocks the ball loose, then the runner is out if the umpire felt the contact was intentional, but it is a loose/live ball if the contact was accidental or otherwise part of the game.
