The problem is that his hand seemed to go up in the air when it reached the plate area. It beat the tag, but not sure he touched the plate since his hand went up.
As for the blocking, I have no idea. He seems to drop, or try to drop, his knees right on the edge of the plate. Seems to be what was a point of emphasis made illegal for the other bases this year, but is that still legal for home plate? Seems weird to me.
