quote:SITUATION 11: R1 is on third and R2 on first with one out. B4 hits a sinking line drive to center field. R1 tags properly and goes home, while R2 is off with the hit. F8 makes a great catch. R2 is beyond second base as F8 throws back to first in an attempt to double up R2. The ball goes into the dugout with R2 still between second base and third base. R2 touches second base and goes back to touch first base. RULING: The ball is dead and R1’s run will count. R2 will be awarded two bases from the base he had at the time of the pitch (first base), so he will be awarded third base. If the defense properly appeals R2 being beyond second base at the time the ball went dead, R2 will be declared out. R1’s run would still count. (5-1-1g-3, 8-2-5, 8-2-6d-1, 8-4-2q)
I don't understand the reasoning of the bolded part. He is allowed to do this as long as he retouches 2nd base, right? Why would this be the rule?
