The thing that gets me, at first, what is the 3rd base coach chirping about? His R2 is safe at third. Hes saying something to U3 right as the play ends. What else did he want?
And watch the umpire at 2nd, hes looking away when he makes the out call, very casually, as if the out is on the force. The fielder tags R1 anyways to be sure, but umpire was looking away.
From what I could find out on the net, seems no one saw the actual tag of R1, so they had to leave him at 2nd
