Situation: runners at second and third, no outs. A line drive gets caught by the short stop, who throws to third base to try and get a double play.
The runner at third is called safe. However, the runner thinks he is called out and starts jogging off the field. The third baseman throws the ball to the pitcher. The pitcher then throws the ball back to the third baseman who steps on third base. The field umpire signals out.
The runner who was originally called safe (and then out) gets as far as the on-deck circle of the first base dugout before his teammates tell him to go back and touch home plate.
The runner comes back and touches home plate. The home plate umpire calls him safe at home and the run scores. Is this a legal run?
I realize that the runner was essentially tagging up, and when the umpire signaled out, it was the wrong call. However, after the runner was signaled out the catcher figured him to be out and therefore allowed the runner to come back and touch home plate.
What should happen when an umpire make a false out call such as this? It is deceptive to the defense; it seems that the runner should have to go back to third at the very least.
