No, not the things that old fashioned nerds used to whip out as regularly as old fashioned porn stars used to whip out their junk, but the rules on sliding into bases, and on over sliding past them. Which is mostly a discussion about technology--now that we have replay cameras, and TV directors who whip them out as frequently as...well, let's skip that whole metaphor and go straight to the root of the problem: folks who might have been okay with umps using their eyesight and their judgment to decide plays on which a runner may have, or may not have, strayed a silly millimeter past a base are NOT apparently okay when a bunch of umps in Chelsea take two minutes of freezing frames and switching angles to decide the same. Me, I love it. I've always been a big supporter of replay cameras. I can't wait personally for ALL of baseball to be ruled by objective measures rather than weak-eyed and strong-willed men who, honestly, are deeply flawed in more ways than I can count, but this is one example where accuracy is needed and human frailty is not. It has ALWAYS been against the rules to break contact with a base while the tag was being applied--the problem in calling this rule was that human umps couldn't always (or even usually) judge whether contact was ever-so-briefly broken. But now we can. The solution to the problem of "BUT I DON'T WANNA GET CALLED OUT!!" is simple: then don't break contact. Slide a little slower, grab the base a little harder, dig your spikes into the dirt a little more to stop your forward motion. It's within YOUR control, runner, to maintain contact with the bag--the fact that it was a bit easier in the past for you to obscure your breaking contact does not make you the victim here. If you mess up, expect the rule to be called against you, even if you only broke contact for a millisecond and by a fraction of an inch. The rule does not state how long or how far you may stray while being tagged. It merely states that you may NOT break contact while being tagged. The fact that technology has advanced where we can confidently call you out doesn't make you safe.
