One? Nope. Can't be. Besides being highly subjective, there is the Top 40 syndrome: what I feel like today I didn't yesterday and won't tomorrow. Baseball is to rife with history to pinpoint such a moment. From tragedy (Gehrig and Puckett) to elation (Fisk's homer, Tug McGraw's "Ya gotta believe) to mystery (death of Ed Delahanty, Babe Ruth's "called" homer), there just isn't a possibility of choosing one thing.
