Watched video over and over, pausing it and looking at head of catcher and R1. Catcher caught the ball protected the ball turned to drop to his knee, the he realized runner not slider, he then came up towards runner. R1 never attempted to slide or avoid contact. I see this as R1, and R2 and their coach. No one should be ejected. Give coaches stern warnings, let both teams calm down, resume play. Any more incidents game cancelled.
