Derek Jeter is off to a scorching start this season, hitting .382/.411/.618 through his first 74 plate appearances. His .432 wOBA currently ranks among the league's best, and is almost 40 points higher than the next best shortstop in baseball.
For Jeter, this is simply a continuation of his torrid second half to the 2011 season. Over his last 388 plate appearances, dating back to July 2011, Jeter has a .379 wOBA. The sample is small enough that we can't conclude he is currently that great of a hitter, but it shouldn't come as a surprise if he continues to rake this year.
His wOBA since the second half of last season is made even more impressive by his age, as Jeter produced those numbers after turning 37 years old. And even if he finishes in the .340 to .345 range, he'll still find himself in limited company, historically, relative to his age and position.
