I love baseball - the game, the strategy, the rules, and the stats. Some events are truly rare, like 4 strike-outs in an inning, or the unassisted triple play. But some things happen only once a century (at least within the major leagues).
On March 24, 2001, while pitching for the Arizona Diamondbacks, Randy Johnson released a fastball, just as a hapless bird flew across the infield. His pitch struck the bird at 90 miles an hour, and the poor creature landed dead in a "sea of feathers." The umpire ruled it a no-pitch. He couldn't call it a strike, or a ball, or an error. I'm not sure if it incremented Johnson's pitch count.
A batted ball has yet to bring down a bird, but I suppose it could happen. Of course there are fewer hits than pitches, so a bird line drive might be even less frequent, perhaps once every 300 years. At that point the umpire would have to make a ruling. Without the interference, would it have been an out or a hit? Maybe he'll call it a fowl ball. (Sorry, I couldn't resist that one.)
Of course I don't want to beam birds with baseballs. I'm sure we would all ike to say, "No animals were harmed in the course of this game."
