rodriguez' 14 home runs

So baseball's best shortstop-playing-thirdbase Alex Rodriguez has hit 14 home runs in 18 games for the Yankees -- the fastest anybody has reached 14 homers at the start of a season. That is a pace for 126 home runs; he'd pass Barry Bonds' single season record of 73 by the All-Star Break.

So what does that prove? Well, not much. We already know Rodriguez (whom I refuse to call A-Rod) is a great hitter. Mostly, it proves that extrapolating statistics from a small sample size is stupid, whether in baseball or in economics or in real life.
