Rizzo was provided a clear lane to get to home. He doesn't even slide - instead, it appears he deliberately tries to make contact with the catcher who had caught the ball and was diving over to make a tag. I think Rizzo should be tossed. IMO, the new rules were correctly put in place to create tag plays at home like they typically occur at second and third base (not with the old breaking up a double play slide, but say when you're trying to steal second). If someone did that to a second baseman on a steal attempt, it would clear the benches and the runner would be toss (IMO).
