why was he out?

Could have been abandonment, could have been tagged out. Hard to tell from the story.

he was tagged but why is he not protected as he made no move towards second?

Because he did not immediately return to the base. 7.08j covers this exact situation: "He fails to return at once to first base after overrunning or oversliding that base. If he attempts to run to second he is out when tagged. If, after overrunning or oversliding first base he starts toward the dugout, or toward his position, and fails to return to first base at once, he is out, on appeal, when he or the base is tagged;"

 

 

 

well i guess that explains it then

I never realized there was an at once in there either

thankyou

Although there is certainly some leeway in the "at once" part, walking back to the dugout is well outside the leeway area.

 

This one's on the 1B coach.
