Softball:What is call when runner is 2nd -3rd base goes back to 2nd and ball is thrown in dead ball territory?

Question

Runner starts 1st base; batter hits deep fly ball into center field; center fielder catches and throws ball to 1st fieldman to put out runner for leaving too soon.

Answer 1

The runner is required to go re-touch 2nd then 1st,then is awarded 2 bases for the infraction of throwing the ball into dead-ball territory.By RULE its one base from the mound two bases from the field.(to clear that up a little,if the pitcher throws a wild pitch that goes out of play the runner/runners are awarded 1 base)(Now if a fielder throwes a ball that goes out of play the runner/runners are awarded 2 bases)
There is no such rule as 1 plus 1 that everybody thinks there is.
