He charged an opposing player. He's the instigator here.
Wait - what? How does the fact that he is jawing at the original runner justify him getting INTENTIONALLY run into by the trailing runner. That runner has ZERO justification for what he did. Not only did he leave the baseline to do it - he did it to a guy who had his back turned. That move went beyond any baseball play and was completely gutless and classless. In Florida he would likely get the next 6 weeks off.
