1. Have the pitcher walk to home plate between pitches, where the catcher will manually deposit the ball directly into his glove. Sure, it'll add several hours to every game, but you can't put a price on safety.
2. Designated fielder. Who wants to see pitchers field, anyway?
3. Something something magnets in the ball?
4. The center fielder should back up that throw. Really this is Dexter Fowler's fault.
