The rule was put in place in the wake of Buster Posey getting creamed a year ago in a collision at home. It is meant to protect the catcher by basically disallowing them from being in the baseline when not having the ball. The problem is, what happens when the ball is thrown into the baseline? The catcher has to go get it without having the ball yet.
A ridiculous "safe" call resulted in the start of a two-out, six-run San Francisco rally over the White Sox yesterday. Properly called without the stupid rule and the Giants would have ended their inning scoreless. In the Mets game against Washington, the "safe" call was not ruled even though by the book it should have. The Mets lost the game by a run.
The inconsistencies of the rule, not to mention that it's really not protecting the catcher all that much as they often still have to go into the baseline to get a throw, should get this rule tossed out quicker than White Sox manager Robin Ventura was yesterday.
Baseball announces a new commissioner today. I have a suggestion for his first act in the position.
