The first point is definitely true and usually the way it ends, and not much is heard about it. The second part might be true, but Machado is from Florida. I think overall baseball has down a pretty good job of cracking down on this, or perhaps the players just aren't as into it as they used to be. There are fewer and fewer incidents each year, which is good, but I'm not certain it can ever 100% be taken out. These are humans, playing competitively at a high level over a long grind of a season. Even if something is an accident like the Machado slide there can be lingering bad blood and it seems to work if there is some sort of an outlet. I generally say hit him in the ass the next time up and move on. Headhunting 2 days later is another story.
