Unless you are north of the border.

Softball Canada Rule 1 section 52.

c. A fielder with possesion of the ball may cause obstruction by:
1) Pushing a runner off base;
2) Impeding the progress of a runner while not in the act of making a play on the runner.

For my American friends, a question. Given that ASA precludes obstruction by a fielder in posession of the ball. What does you call when a fielder pushes a runner off base and tags them? USC and eject ?
