We're ignoring the true idiot in this fight.
Justin Smoak hit the ground ball that resulted in Bautista's force out at second. Odor's attempted decapitation of Bautista resulted in a wild throw that went to the railing. The Rangers, being the dumbasses they are, immediately ran to the fight and abandoned the ball.
So Smoak, with his team trailing by one run in the eighth inning, was presented with a live, loose ball, and three uncovered bases in front of him. So what did he do?
He ran into the fight as well, thus getting himself called out for leaving the base path.
