You know, if they start downsizing the "neighborhood" to the actual bag (eliminate the rule), then 1 of 2 things happens: infielder injuries go up as they meet runners at the bag, or they take the "safe" out only and get out of the way, reducing the number of double plays.
Is the latter result all that bad? Why is it good to allow fielders essentially to cheat (avoid actually touching 2d base) so as to get an extra out (by turning the phantom double play)? You want to get two outs on one play, earn it. If you can't turn two without putting yourself in harm's way, then just take one out. It's like the QB that tosses the ball out of bounds to avoid either a turnover or a vicious hit. Live for the next play.
Yeah, I think making the neighborhood play reviewable (and thus enforced) is by far the bigger change here. The excuse for the neighborhood play up until now was it was necessary to protect players from takeout slides. Well, if there are no takeout slides, no excuse remains, so the practice stops making a farce of one of baseball's core rules (gotta step on the bag to get the force-out).
I think this will play out very much like how forceouts work at first base: the fielder will try to position their body to the side of the bag, and only just touch the bag with a trailing foot, while expecting (indeed, counting on) the runner to go for the bag but conscientiously avoid contact. Yes, you can overrun first base, so it's not an exact analogy, but if the fielder isn't in your path you really have no reason (well, no
sporting reason) to try and take him out.
My complaint is actually that this doesn't go far enough. This doesn't sufficiently disincentivize takeout slides, because a runner trying to break up a double play knows that the downside (if his slide is ruled illegal) is a double play - exactly the same as if he had allowed the pivot man to go through with it untouched. He has no incremental downside to having his slide ruled an illegal takeout. If an ump feels that a takeout slide is not just illegal but intentionally so (e.g. Utley, or Scutaro above), the rules should suggest that he eject the runner from the game. Takeout slides are a practice that's about as reckless, dangerous and unnecessary as a hit batsman charging the mound; it should carry a similar penalty.
I am delighted with the addition to the baseball lexicon of "bona fide slide."
I believe they took it directly from the lyrics to Red Hot Chili Peppers' "Around the World".
