An arcane regulation led to a controversial call in the Cardinals-Braves game a week ago. But there's a good reason that the regulation exist.
Baseball's Infield Fly Rule has sparked more legal fascination than any other rule in sports. It returned to the national spotlight this past week when an unusual and controversial infield fly call in last Friday's National League Wild Card game between the St. Louis Cardinals and Atlanta Braves short-circuited a potential Braves rally in a game the Braves ultimately lost. Opinion has been divided on the correctness of the call.
But beyond criticism of this specific call, some fans on Twitter and in web forums expressed a deeper distaste for the Infield Fly Rule itself, questioning whether it is necessary, wise, or warranted. They're misguided: The rule is part of the sport's fabric, uniquely warranted for a situation that's unique to baseball.
Here's how the Infield Fly Rule works. When a team has runners on first and second or the bases loaded with less than two out and the batter hits a pop-fly ball (but not a line drive) in fair territory that can be easily caught by an infielder (under the rule, can be caught with "ordinary effort"), the batter is called out, regardless of whether the fielder catches the ball; if the ball drops and remains fair, it is in play and the runners can try to advance at their own risk. The rule is designed to remove the incentive for a fielder to deliberately drop an easily handled ball on the infield, which likely would allow him to turn a double play on the two base runners (and perhaps, although less likely, a triple play). It took its more-or-less current form in 1901, enacted in response to infielders actually doing this, a bit of trickery that was deemed not "sporting" at the time.
